Before Bombay: The Forgotten Railways of the Madras Presidency

Before Bombay

Revisiting the Forgotten Railways of the Madras Presidency (1832–1941)

The accepted origin of Indian Railways is usually placed in 1853. Yet, this narrative, while convenient, is incomplete.

Long before the first passenger train ran in Bombay, the Madras Presidency had already witnessed the earliest proposals, experiments, and working railway systems in India. These were not grand, celebrated undertakings — but practical responses to commerce, geography, and crisis.

The earliest railways in India were not built for travel — but for transport, survival, and necessity.

“Ennulle Ennulle” – A Deep Musical Exploration of Ilaiyaraaja’s Keeravani Masterpiece

Among the many raga-based songs in Tamil cinema, “Ennulle Ennulle” from the 1993 film Valli occupies a special place. Composed by Ilaiyaraaja, written by Vaali, and sung by Swarnalatha, the song stands as one of the most haunting musical expressions built upon the Carnatic raga Keeravani.

The composition is admired not merely for its melodic beauty but for the remarkable emotional depth that emerges from the fusion of Carnatic melodic grammar and Western harmonic sensibility. More than three decades after its release, the song continues to resonate with listeners as a deeply introspective musical experience.

Song Structure

Ilaiyaraaja structures the song in a classical cinematic format where instrumental passages play a significant role in developing the emotional landscape.

• Prelude (Instrumental Introduction)
• Pallavi
• Interlude 1
• Charanam
• Interlude 2
• Final Pallavi

Each instrumental interlude functions almost like a miniature composition, extending the emotional atmosphere of the raga.

The Raga Foundation – Keeravani

Keeravani is the 21st Melakarta raga in Carnatic music and corresponds closely to the Western harmonic minor scale.

Scale Structure

Arohanam (Ascending)

S R₂ G₂ M₁ P D₁ N₃ S

Avarohanam (Descending)

S N₃ D₁ P M₁ G₂ R₂ S

Western Equivalent (Example in C)

C – D – E♭ – F – G – A♭ – B – C

The raised seventh note (N₃) produces a powerful gravitational pull towards the tonic note. This tonal tension gives Keeravani its characteristic emotional colour — a blend of melancholy, longing, and introspective intensity.

---

Keyboard Visualisation of Keeravani

Below is a simple keyboard representation of the Keeravani scale (in C).

C   D   Eb  F   G   Ab  B   C
S   R₂  G₂  M₁  P   D₁  N₃  S

Notice the combination of flattened third and sixth with a raised seventh. This unusual pattern gives the harmonic minor scale its dramatic character.

---

Visualising the Emotional Geometry of Keeravani

The emotional intensity of Keeravani emerges from its distinctive interval pattern. Unlike the natural minor scale, the harmonic minor introduces a raised seventh note, creating a dramatic tension before resolving to the tonic.

Interval Pattern

S  →  R₂  →  G₂  →  M₁  →  P  →  D₁  →  N₃  →  S
W     H      W      W      H      Aug2    H

In Western terms, the intervals can be represented as:

Whole – Half – Whole – Whole – Half – Augmented Second – Half

The unusual augmented second interval between D₁ and N₃ is what gives the harmonic minor scale its distinctive dramatic pull. This interval introduces a sense of emotional tension that feels unresolved until the melody reaches the tonic.

Melodic Movement in Keeravani (Phrase Illustration)

The emotional character of Keeravani comes not just from its notes, but from how the melody moves between them. The simple illustration below shows a typical phrase movement used in the song.

Sa → Ri₂ → Ga₂ → Ma₁
        ↓
       Ga₂
        ↓
       Ri₂
        ↓
       Sa

A rise followed by a gentle return — a hallmark of Keeravani’s introspective mood

Notice how the phrase ascends gradually and then folds back inward. This rise-and-return movement creates a feeling of emotional reflection, as if the melody is turning back towards itself.

This inward-turning motion is one of the reasons Keeravani often evokes longing and introspection.

In “Ennulle Ennulle”, Ilaiyaraaja repeatedly uses this tension between Dhaivatam (D₁) and Nishadam (N₃) to create a sense of longing within the melodic line.

Natural Minor vs Harmonic Minor

Natural Minor:   C  D  Eb  F  G  Ab  Bb  C
Harmonic Minor:  C  D  Eb  F  G  Ab  B   C

Notice how the raised seventh note (B instead of Bb) intensifies the pull towards the tonic. This simple alteration transforms the emotional character of the scale — from gentle melancholy to dramatic introspection.

This is precisely the emotional landscape that Ilaiyaraaja explores in “Ennulle Ennulle”.

Scale and Rhythmic Framework

“Ennulle Ennulle” is set around a tonal centre of C♯ (C-sharp), which functions as the Sa (tonic). This pitch framework supports the raga Keeravani, whose scalar structure closely corresponds to the harmonic minor scale in Western music.

The song is structured in Adi Talam, the most widely used rhythmic cycle in Carnatic music, consisting of 8 beats grouped as 4 + 2 + 2. This rhythmic framework provides both stability and flexibility, allowing the composition to move seamlessly between structured passages and more fluid, expressive phrasing.

What is particularly noteworthy is how the rhythmic discipline of Adi Talam coexists with the song’s free-flowing melodic lines. While the underlying tala remains constant, the phrasing often stretches across beat boundaries, creating a sense of emotional continuity rather than rigid metric segmentation.

This balance between rhythmic structure and melodic fluidity is a hallmark of Ilaiyaraaja’s compositional style, where classical foundations are adapted to serve cinematic expression without losing their intrinsic musical integrity.

Keeravani Scale (Visual Representation)

The raga Keeravani follows a symmetrical ascending and descending structure. Its scale can be represented as:

Sa – Ri₂ – Ga₂ – Ma₁ – Pa – Dha₁ – Ni₃ – Sa

C♯ – D♯ – E – F♯ – G♯ – A – B♯ – C♯

In Western terms, this corresponds closely to the harmonic minor scale. The distinctive feature of this scale is the raised seventh (Ni₃), which creates a strong pull toward the tonic and contributes to the raga’s intense, introspective character.

Sa   Ri₂   Ga₂   Ma₁   Pa   Dha₁   Ni₃   Sa
|----|-----|-----|-----|----|------|------|
C♯   D♯    E     F♯    G♯   A      B♯     C♯

This scalar framework forms the melodic foundation of “Ennulle Ennulle”, within which Ilaiyaraaja crafts phrases that move between restraint and emotional intensity.

Melodic Architecture of the Song

Ilaiyaraaja constructs the melody in a way that preserves the raga identity while allowing it to flow naturally within a cinematic framework.

Pallavi Phrase Example

N₃ S R₂ G₂
G₂ M₁ P
D₁ N₃ S

Delayed Tonic Resolution: A Subtle Emotional Device

One of the most striking compositional subtleties in “Ennulle Ennulle” is the way Ilaiyaraaja delays the resolution to the tonic (Sa) in the opening melodic phrase. In many compositions based on the raga Keeravani, the melodic movement often establishes the tonal centre early, giving the listener a clear sense of resolution.

Here, however, the melody initially hovers around the middle notes of the scale, particularly emphasising Ga and Ma, before gradually descending toward the tonic. This deliberate hesitation creates a subtle sense of suspension, as if the music itself is searching for emotional grounding.

When the phrase finally settles on the tonic, the effect is quietly powerful. The listener experiences a moment of release, not through dramatic orchestration but through melodic inevitability.

This technique is closely related to how tension and release operate in both Carnatic melodic thinking and Western harmonic phrasing. By delaying the tonal resolution, Ilaiyaraaja allows the emotional atmosphere of the song to deepen before the melodic centre is firmly established.

In the context of the song’s theme of inward reflection, this delayed arrival at the tonic beautifully mirrors the emotional journey suggested by the lyrics — a gradual unfolding of inner feeling rather than an immediate declaration.

Characteristic Keeravani Movement

S R₂ G₂ M₁
P D₁ N₃ S
S N₃ D₁ P

These movements highlight the raga’s emotional tension between Gandharam and Nishadam.

---

The Opening Prelude

The song begins with a striking instrumental introduction that subtly blends classical rhythmic energy with cinematic orchestral colour. The very first moments feature a percussive passage resembling a Bharatanatyam jathi, performed through a combination of instruments akin to mridangam, kanjira, and other traditional percussion timbres.

This rhythmic opening reflects the intense Bharatanatyam dance sequence shown in the film before the song itself begins. The percussion patterns carry the structured rhythmic character typical of classical dance, creating an energetic yet controlled beginning.

Following this rhythmic flourish, the music transitions seamlessly into an atmospheric soundscape. Soft synthesiser textures and sustained string pads begin to dominate the sonic field, forming a gentle harmonic cushion.

Rather than presenting the raga Keeravani immediately in its full melodic form, Ilaiyaraaja introduces fragments of the scale gradually. This restrained approach creates a mood of quiet introspection, allowing the emotional world of the song to emerge slowly before the voice enters.

In many ways, this introduction functions almost like an instrumental alapana, where the raga’s tonal colour is hinted at rather than fully declared. The listener is gently guided into the emotional landscape of the composition before the main melody unfolds.

---

Time-Coded Musical Breakdown

0:00 – Prelude

The song opens with an evocative instrumental prelude that bridges rhythm and atmosphere. A brief percussive introduction featuring instruments resembling mridangam, kanjira, and other folk percussion establishes a lively rhythmic pattern reminiscent of a Bharatanatyam jathi. This rhythmic flourish connects directly to the dance sequence depicted in the film.

As the percussion settles, atmospheric synthesiser textures and sustained string pads emerge, gently establishing the tonal centre. Rather than immediately presenting the complete melodic framework of the raga, Ilaiyaraaja allows the harmony and texture to prepare the listener’s ear before the melody unfolds.

0:22 – Pallavi Begins

Swarnalatha enters with the iconic phrase “Ennulle Ennulle”, immediately establishing the raga identity.

1:05 – First Interlude

Strings echo fragments of the main melody while synthesiser layers sustain the harmonic background.

1:30 – Charanam

The melody expands into a slightly wider emotional range while remaining anchored in the Keeravani framework.

2:15 – Second Interlude

A richer orchestral texture appears, featuring a dialogue between strings and electronic timbres.

3:00 – Final Pallavi

The melody returns with emotional maturity, giving the song a sense of quiet resolution.

---

Inside the Interludes: Ilaiyaraaja the Orchestrator

In many Ilaiyaraaja compositions, the interludes are not merely transitional passages. They function as miniature orchestral narratives that deepen the emotional context of the song.

In “Ennulle Ennulle”, the interludes expand the inner emotional world suggested by the lyrics and melody.

First Interlude – Echoes of the Inner Voice

The first interlude gently mirrors the melodic fragments of the pallavi. The orchestration remains restrained, allowing the raga atmosphere to remain intact.

• Soft string phrases echo fragments of the vocal melody
• Synth pads sustain the harmonic atmosphere
• Bass movement subtly reinforces the tonal centre

Rather than introducing contrast, the interlude feels like a continuation of the emotional thought expressed in the pallavi.

Second Interlude – Expanding the Emotional Space

The second interlude introduces a slightly richer orchestral texture. Here Ilaiyaraaja allows the harmonic possibilities of the harmonic minor scale to become more prominent.

• Layered string textures widen the sonic space
• Synth lines provide atmospheric colour
• Instrumental dialogue creates gentle forward motion

Yet even here, the orchestration never becomes dramatic or overpowering. The music continues to breathe within the quiet introspection of Keeravani.

The Philosophy Behind the Interludes

Ilaiyaraaja often treats instrumental interludes as emotional reflections rather than structural necessities. Instead of merely filling space between vocal sections, these passages allow the listener to absorb the emotional weight of the melody.

In “Ennulle Ennulle”, the interludes feel like wordless thoughts — moments where the music speaks after the voice falls silent.

This is one of the defining characteristics of Ilaiyaraaja’s orchestral style: the ability to transform instrumental passages into emotional storytelling.

The Interludes – Ilaiyaraaja the Orchestrator

First Interlude

• String phrases mirror fragments of the vocal melody
• Subtle synthesiser pads maintain the harmonic atmosphere
• The orchestration remains soft and introspective

Second Interlude

• Instrumental dialogue becomes more pronounced
• Harmonic movement reflects the Western harmonic minor scale
• The transition gently guides the listener back into the vocal section

These interludes demonstrate Ilaiyaraaja’s extraordinary ability to transform instrumental passages into emotional extensions of the song.

---

Swarnalatha’s Vocal Interpretation

Swarnalatha’s voice carries a fragile emotional quality that perfectly suits the introspective nature of the composition.

Subtle Gamakas

Rather than elaborate classical ornamentation, the gamakas remain restrained. This allows the emotional content of the melody to remain clear and direct.

Sustained Emotional Notes

Key notes such as Nishadam and Gandharam are occasionally sustained, creating moments of suspended emotional tension.

---

Vaali’s Lyrics – The Poetry of Inner Emotion

The lyrics written by Vaali explore themes of inward reflection and emotional awakening.

The phrase “Ennulle Ennulle” itself suggests something stirring within the heart — an emotion that is not yet fully expressed.

This lyrical theme aligns perfectly with the introspective nature of Keeravani, where emotional intensity remains internal rather than outwardly dramatic.

---

Harmony – The Western Connection

Because Keeravani corresponds to the harmonic minor scale, it allows Ilaiyaraaja to introduce harmonic ideas rarely found in traditional Carnatic compositions.

Typical harmonic suggestions include movements like:

• i – iv – V
• i – VI – V
• i – vii° – i

These harmonic colours enrich the melodic structure without overshadowing the raga identity.

---

Why Keeravani Works So Well in Film Music

One of the fascinating reasons Keeravani appears frequently in film music is its remarkable compatibility with both Carnatic melody and Western harmonic language.

Because the raga corresponds closely to the harmonic minor scale, it naturally supports chord progressions and orchestral textures commonly used in Western composition. This allows film composers to retain a classical melodic identity while simultaneously expanding the harmonic landscape of the music.

The Psychology of the Harmonic Minor Scale

The emotional power of the harmonic minor scale lies primarily in its raised seventh note. This note creates a strong pull toward the tonic, producing a sense of tension that seeks resolution.

In psychological terms, listeners often perceive this tonal tension as a feeling of yearning or emotional anticipation. The music seems to hover between melancholy and fulfilment.

This is why melodies built on harmonic minor scales frequently evoke moods such as:

• Longing
• Romantic intensity
• Introspection
• Mystery
• Spiritual depth

The Dramatic Interval

Another defining feature of the scale is the augmented second interval between the sixth and seventh notes. This interval is relatively rare in many Western scales, and its presence introduces a distinctive dramatic colour.

Example in C Harmonic Minor:

C  D  Eb  F  G  Ab  B  C
            ↑
       Augmented Second

This unusual leap creates an emotional intensity that composers often exploit when expressing inner conflict, longing, or emotional transformation.

Why Ilaiyaraaja Uses Keeravani So Effectively

Ilaiyaraaja’s musical language frequently blends Carnatic melodic grammar with Western harmonic orchestration. Keeravani becomes an ideal bridge between these two musical worlds.

In songs like “Ennulle Ennulle”, he preserves the raga identity in the melody while enriching the emotional landscape through harmonic movement and orchestral colour.

The result is music that feels simultaneously classical, cinematic, and deeply human.

Keeravani in Ilaiyaraaja’s Musical Language

Ilaiyaraaja has explored Keeravani in several memorable compositions. The raga’s compatibility with the harmonic minor scale makes it particularly suitable for cinematic orchestration.

• Mannil Indha Kaadhal
• Poove Sempoove
• Keeravani

Each of these songs demonstrates a different emotional dimension of the raga.

---

The Emotional Journey of the Song

Introspection

The opening atmosphere invites quiet reflection.

Awakening

The melody gradually expands, suggesting emotional realisation.

Acceptance

By the end of the song, the music settles into contemplative calm.

---

Why “Ennulle Ennulle” Endures

The enduring appeal of this composition lies in the rare convergence of several musical strengths:

• The emotional richness of Keeravani
• Ilaiyaraaja’s orchestral imagination
• Swarnalatha’s haunting vocal tone
• A melody that captures introspection with sincerity

The song does not merely illustrate a raga; it inhabits it.

---

Conclusion

“Ennulle Ennulle” remains one of the most powerful examples of raga-based film composition in Tamil cinema. Through a delicate balance of melody, orchestration, and poetry, Ilaiyaraaja transforms Keeravani into a cinematic emotional landscape.

What emerges is not simply a film song but a musical meditation — one that continues to echo quietly within listeners long after the final note fades.

---

Some songs remain with us long after the last note fades. “Ennulle Ennulle” is one of those rare melodies where raga, voice, and orchestration quietly meet the inner world of the listener.

The Quiet Radiance of Four Ragas in Cinema

The Quiet Radiance of Four Ragas in Cinema
Saranga • Saranga Tarangini • Saavithri • Saindhavi

In the vast soundscape of South Indian cinema, certain melodies linger in the mind long after the film has ended. Often the listener may not immediately recognise why a song feels unusually beautiful or emotionally resonant. The answer frequently lies in the subtle presence of a classical raga guiding the melody beneath the orchestration.

---

Introduction

Carnatic ragas have shaped the melodic language of South Indian film music for more than half a century. From the early studio era of the 1950s to the richly orchestrated soundtracks of later decades, composers have repeatedly drawn inspiration from the classical tradition.

While certain ragas such as Kalyani, Mohanam, and Shankarabharanam appear regularly in cinema, many others appear only occasionally. Yet these rarer ragas often produce some of the most memorable musical moments.

This essay explores four such ragas that have quietly enriched film music: Saranga, Saranga Tarangini, Saavithri, and Saindhavi.

Though very different in structure, each of these ragas possesses a distinct emotional colour. Through carefully chosen film songs we can observe how composers translated these classical frameworks into cinematic melodies that remain both accessible and musically sophisticated.

---

Preface

A raga is far more than a scale. In Carnatic music it represents a complete melodic personality shaped by characteristic phrases, tonal emphasis, and aesthetic mood.

When a raga enters the world of film music, it undergoes subtle transformation. Strict classical grammar relaxes slightly as composers introduce harmony, orchestration, and rhythm drawn from diverse musical traditions.

Yet the most successful film compositions retain the essence of the raga. The listener may not consciously recognise the classical structure, but the emotional impact remains unmistakable.

The songs presented here illustrate this delicate balance between tradition and creative adaptation.

---

Saranga

Saranga is a graceful and luminous raga whose melodic phrases move with gentle curvature. One of its defining features is the appearance of both madhyamams in the descending scale, which produces subtle tonal colour changes.

Scale Structure

Arohanam
S R2 S P M2 P D2 N3 S

Avarohanam
S D2 P M2 R2 G3 M1 R2 S

Because of this unique structure, Saranga often evokes emotions of warmth, romantic tenderness, and reflective calm.

Kaadhalil Maatamal – Parvathi Ennai Paradi

The melodic phrases in this composition reveal Saranga’s characteristic movement between the upper and middle registers. The gentle oscillations give the song a soft romantic glow.

Oru Dhevadhai Vandhadhu – Naan Sonnadhe Sattam

This song demonstrates how Saranga adapts beautifully to cinematic storytelling. The orchestration remains restrained, allowing the melody itself to carry the emotional narrative.

---

A Tribute to M. S. Viswanathan – A Classic Saranga Interpretation

Among the early cinematic interpretations of Saranga, one composition stands out as a timeless gem. The song “Konja Neram Ennai” from the 1974 film Sirithu Vazha Vendum was composed by the legendary M. S. Viswanathan, often celebrated as one of the architects of modern Tamil film music.

Sung by T. M. Soundararajan and S. Janaki, with lyrics by Vaali, the composition captures the lyrical elegance of Saranga while remaining fully accessible to film audiences. The melody moves gracefully through the raga’s characteristic phrases, revealing the gentle tonal shifts created by the two madhyamams in descent.

The orchestration is restrained yet expressive. Strings and flute passages complement the melody without overshadowing it, allowing the raga’s delicate structure to shine through. The interplay between the voices of T. M. Soundararajan and S. Janaki adds a further emotional dimension to the composition.

This song remains one of the finest cinematic examples of Saranga and serves as a fitting tribute to the melodic imagination of M. S. Viswanathan, whose work helped establish a bridge between Carnatic musical ideas and popular film music.

Saranga Tarangini

Saranga Tarangini is a relatively rare raga whose name evokes flowing waves. Belonging to the melodic family of the 65th melakarta Mecha Kalyani, the raga possesses a luminous tonal colour due to the presence of Prati Madhyamam.

Scale Structure

Arohanam
S R2 M2 P D2 N3 S

Avarohanam
S N3 D2 P M2 R2 S

The omission of Gandharam creates a spacious melodic environment where phrases flow smoothly between the upper and middle registers.

Isaiyil Thodangudhamma – Hey Ram

Sorgame Endralum – Ooru Vittu Ooru Vandhu

Thendral Vandhu Ennai Thodum – Thendrale Ennai Thodu

These songs illustrate how the raga’s wave-like motion translates naturally into cinematic melody. Ilaiyaraaja in particular demonstrates remarkable sensitivity in preserving the raga’s essence while expanding it through orchestration.

---

Saavithri

Saavithri is a pentatonic raga whose simplicity lends itself beautifully to lyrical compositions. Because it contains only five notes, the melodic lines remain clear and uncluttered.

Scale Structure

Arohanam
S G3 M1 P N2 S

Avarohanam
S N2 P M1 G3 S

Film Song Illustrations

Antha Randoi Randi – Chinnabbayi

Chithira Sevvaanam Sirikka Kandaen – Kaatrinile Varum Geetham

Chukkalu Temmanna – April 1 Vidudala (1991)

Epilogue

The journey of ragas into cinema reveals the extraordinary adaptability of Indian melodic traditions. Even within modern orchestration, the emotional core of a raga continues to shine through.

---

Coda

Cinema has become an unexpected archive of classical melodic ideas. Songs composed decades ago continue to introduce new generations of listeners to the beauty of ragas.

---

Closing Reflections

When we listen carefully to film songs through the lens of raga, an entire musical universe unfolds. Each melody becomes a bridge between classical heritage and contemporary creativity.

Preface
Across India’s landscapes lie numerous geological archives that quietly record the planet’s encounters with deep time and cosmic forces. Some preserve the memory of ancient oceans, others bear witness to the slow collision of continents and the rise of mountain ranges. A few, however, tell a different story — one of sudden encounters with objects arriving from space.

Among these rare sites, Lonar Crater stands apart as one of the most remarkable natural laboratories for understanding meteorite impacts in basaltic rock. Formed within the ancient Deccan Traps, the crater offers scientists a unique window into planetary collisions and provides valuable insights into similar impact processes on the Moon and Mars.

Lonar Crater: Where the Earth Remembered the Sky

Lonar Crater panorama. Photograph by Abhijit Juvekar, my long-time friend and an avid astronomy enthusiast whose passion for astronomy, geology, and cosmology reflects the same curiosity that inspired this exploration of the crater.

Across the basaltic plains of Maharashtra lies one of Earth’s most remarkable geological archives — a near-perfect circular depression that silently records a moment when our planet briefly encountered the wider cosmos. Known today as Lonar Crater, this structure was created tens of thousands of years ago when a meteoroid struck the Deccan basalt plateau with immense energy.

Unlike most terrestrial impact sites, Lonar formed within a vast volcanic province composed entirely of basalt — the ancient lava flows of the Deccan Traps. Because of this rare geological setting, the crater has become one of the most important natural laboratories for studying meteorite impacts in volcanic terrain.

Today Lonar stands at the intersection of several fields of inquiry. It is simultaneously a geological archive of a cosmic collision, a planetary analogue for impact processes on the Moon and Mars, and a cultural landscape layered with centuries of human history.

---

Location and Setting

Lonar Crater lies in the Buldhana district of Maharashtra in western India, approximately 500 kilometres northeast of Mumbai. The structure forms a near-perfect circular depression within the basaltic plateau of the Deccan Traps, surrounded by a raised rim of uplifted rock that rises above the surrounding terrain.

At the centre of the crater lies Lonar Lake, a saline and alkaline water body whose unusual chemistry reflects both the closed nature of the basin and the mineral composition of the surrounding basaltic rock.

• Diameter: ~1.8 kilometres
• Depth: ~150 metres
• Estimated Age: approximately 35,000–50,000 years
• Impact Velocity: roughly 11–20 km/s

Although modest in size compared with the giant impact basins found elsewhere in the Solar System, Lonar is scientifically remarkable because it formed entirely within basalt — the same volcanic rock that dominates extensive regions of the Moon and Mars.

---

The Moment of Impact

Sometime during the late Pleistocene epoch, a small celestial body — likely a stony meteoroid — entered Earth’s atmosphere at tremendous cosmic velocity. Travelling at tens of kilometres per second, the object streaked across the sky before striking the basaltic plateau of what is today the Deccan region of India.

In a fraction of a second, the kinetic energy of the incoming body was converted into heat, pressure, and shock. The impact released energy equivalent to several megatons of TNT, far exceeding any conventional explosion produced by human technology. Temperatures at the impact point briefly rivalled those found on the surface of the Sun, while pressures rose to hundreds of thousands of times the normal atmospheric pressure.

The shock wave propagated through the basaltic rock with extraordinary force. Layers of solid lava flows fractured, melted, and in some places were transformed into glassy materials known as impact glass. Fragments of shattered basalt were hurled outward in all directions, forming the raised circular rim that still surrounds the crater today.

Within seconds, the violently excavated cavity collapsed inward. Rock and debris slid back toward the centre while a ring-shaped ridge formed along the outer margin of the crater. What remained was a near-perfect circular depression nearly two kilometres wide — a scar in the ancient basalt plateau that would later fill with water to become what we now know as Lonar Lake.

Although the meteoroid itself was largely vaporised by the immense heat of the collision, the geological evidence it left behind continues to tell the story of that brief but extraordinary cosmic event.

---

The Deccan Basalt: The Ancient Stage Before the Impact

Long before the meteoroid struck, the land that would one day hold Lonar Crater was part of one of the largest volcanic provinces on Earth — the Deccan Traps. These immense basalt formations were created around 66 million years ago during a period of extraordinary volcanic activity near the end of the Cretaceous period.

Instead of erupting from a single volcanic mountain, lava emerged through vast fissures in the Earth’s crust. Rivers of molten rock spread across the landscape, cooling and solidifying into broad, layered sheets of basalt. Over thousands of years, eruption followed eruption, stacking these flows one above another.

The result was a colossal basalt plateau that eventually covered more than 500,000 square kilometres of western and central India. Even today the step-like hills and plateaus of the region reveal these stacked lava flows, giving rise to the name “Traps,” derived from the Swedish word trappa, meaning stair.

Each visible layer represents a separate volcanic episode, a frozen record of ancient lava floods that reshaped the Indian subcontinent. These rocks would remain largely undisturbed for tens of millions of years, forming the stable geological platform upon which the later cosmic impact occurred.

This basaltic composition makes Lonar particularly important to planetary scientists. Much of the surface of the Moon and large regions of Mars are also dominated by basaltic plains formed by ancient volcanic activity. Because of this, Lonar serves as a natural laboratory on Earth where scientists can study how meteorite impacts behave in volcanic terrain similar to those found on other planetary worlds.

---

Shock Metamorphism

One of the most important geological signatures of meteorite impacts is shock metamorphism. When a meteoroid strikes the Earth at cosmic velocity, it generates an intense shock wave that travels through the surrounding rock at extraordinary speed.

For a brief moment, pressures can exceed hundreds of thousands of times normal atmospheric pressure, while temperatures rise to levels capable of melting or even vaporising rock. Under these extreme conditions, minerals are transformed in ways that rarely occur through ordinary geological processes such as volcanism or tectonic activity.

At Lonar, scientists have identified several of these distinctive shock features, preserved within the basalt surrounding the crater. They include:

• Impact glass and melt fragments formed when basalt briefly melted and rapidly cooled.
• Maskelynite, a glassy material produced when the mineral feldspar is transformed by extreme shock pressure.
• Brecciated basalt, where rocks were shattered and fused together into angular fragments.
• Radial and concentric fracture patterns created as the shock wave propagated outward from the point of impact.

These features cannot easily be explained by volcanic eruptions or normal geological deformation. Their presence provided decisive evidence that Lonar Crater was formed by an extraterrestrial impact, ending earlier debates that had suggested a volcanic origin.

Simple and Complex Impact Craters

Impact craters on planetary surfaces are generally classified into two main types: simple craters and complex craters. The distinction depends largely on the size of the impact and the gravitational conditions of the planetary body on which the crater forms.

Simple craters are relatively small and typically have a bowl-shaped structure with a smooth circular rim. Their interiors lack major structural features such as central peaks or terraced walls. These craters form when the energy of the impact excavates material outward but is not large enough to cause major structural collapse within the crater.

Complex craters, on the other hand, are much larger. After the initial excavation stage, the crater walls collapse inward and the floor rebounds upward, often forming a central peak or a series of terraced steps along the inner walls. Many of the large craters observed on the Moon and Mars belong to this category.

With a diameter of roughly 1.8 kilometres, Lonar Crater falls within the size range of a simple impact crater. Its bowl-like shape, well-defined circular rim, and relatively smooth interior slopes are characteristic of this category.

Despite its modest size, Lonar remains scientifically important because it formed within basaltic rock — the same material that covers extensive plains on the Moon and Mars. As a result, the crater provides valuable insights into the formation of simple impact craters on other planetary surfaces.

Impact Glass and Melt Spherules

Among the most striking microscopic traces of the Lonar impact are small glassy fragments and tiny spherical droplets of once-molten rock. When the meteorite struck the Deccan basalt plateau at cosmic velocity, temperatures at the impact site rose to several thousand degrees Celsius, hot enough to partially melt the surrounding rock.

Some of this molten material was violently ejected into the air along with fragmented basalt. As the droplets travelled outward through the atmosphere, they cooled rapidly and solidified into small rounded beads known as impact spherules. These glassy particles can still be found within the ejecta deposits surrounding the crater.

In addition to these spherules, larger fragments of impact glass formed when molten basalt cooled quickly upon contact with the ground. Such materials provide important evidence for the extreme temperatures and pressures generated during meteorite impacts.

The presence of impact glass and melt spherules at Lonar confirms that the collision involved enormous energy, capable of melting solid rock in an instant. Similar glassy materials have been observed in impact structures on the Moon and in meteorite craters elsewhere on Earth, further strengthening Lonar’s significance as a natural laboratory for studying planetary impact processes.

---

Magnetic Signatures of the Impact

Beyond the visible crater structure, the Lonar impact also produced subtle changes in the magnetic properties of the surrounding basalt. Geophysical surveys conducted within and around the crater have revealed distinctive magnetic anomalies caused by the intense shock of the meteorite collision.

Basaltic rocks of the Deccan Traps contain magnetic minerals, primarily magnetite. During the moment of impact, the enormous temperatures and pressures generated by the shock wave partially melted and altered these minerals. In some areas, the original magnetic orientation of the rocks was disturbed or reset.

As a result, scientists have detected variations in the magnetic field across the crater floor and rim. These magnetic signatures provide additional evidence confirming the impact origin of the structure and help researchers reconstruct the physical processes that occurred during the collision.

Such magnetic studies are also valuable in planetary science. Similar magnetic anomalies have been detected in impact structures on the Moon and Mars, making Lonar an important terrestrial analogue for interpreting geophysical data from other planetary bodies.

The Lake Within the Crater

Over thousands of years, rainfall gradually accumulated within the crater basin, forming what is now known as Lonar Lake. Because the crater has no natural outlet, dissolved minerals slowly concentrated in the water, giving the lake its unusual chemistry. Today the lake is both saline and alkaline, a rare combination that distinguishes it from most inland water bodies.

An intriguing hydrological system exists within the crater. Several freshwater springs emerge along the inner slopes of the rim, feeding small streams that flow toward the lake. As a result, the outer margins of the lake can contain relatively fresh water, while the deeper central portions remain strongly saline and alkaline.

This chemical gradient has created a unique ecological environment. Microbial communities adapted to extreme conditions — often referred to as extremophiles — thrive within the lake’s waters and sediments.

Because similar saline and alkaline environments may have existed on early Mars and other planetary bodies, Lonar Lake has attracted considerable interest from scientists studying astrobiology and the potential for life in extreme planetary environments.

---

Lonar Among the World's Crater Lakes

Impact craters containing lakes occur in several parts of the world, but Lonar stands apart because of its geological setting and water chemistry. Most known crater lakes formed in sedimentary or crystalline rock, whereas Lonar developed entirely within the basaltic lava flows of the Deccan Traps.

Because basalt dominates the surfaces of the Moon and large regions of Mars, Lonar provides planetary scientists with a rare natural laboratory for studying impact processes in volcanic terrain. For this reason, the crater has attracted the attention of researchers interested in comparative planetary geology.

Several other well-known crater lakes illustrate how unusual Lonar is:

• Pingualuit Crater Lake (Canada)
  A nearly perfect circular crater lake located in northern Quebec. Its water is exceptionally clear and fresh, in contrast to the saline-alkaline chemistry of Lonar.
• Lake Bosumtwi (Ghana)
  Formed roughly one million years ago, this crater lake occupies a tropical forest basin and is culturally significant to local communities. The lake is freshwater and supports a rich ecosystem.
• Barringer Crater (United States)
  Although similar in age to Lonar, this famous crater in Arizona remains dry and formed in sedimentary rock rather than basalt.

Among these examples, Lonar remains exceptional for combining three rare characteristics: formation in basaltic rock, the presence of a saline-alkaline lake within the crater basin, and its role as a planetary analogue for impact craters on other worlds.

---

The Unusual Waters of Lonar Lake

The lake occupying the floor of Lonar Crater is not an ordinary body of water. Because the crater forms a closed basin with no natural outlet, rainwater that accumulates within it gradually interacts with the basaltic rocks of the crater walls and floor. Over time, this process has produced water that is both saline and strongly alkaline.

The chemistry of the lake reflects the geological environment of the Deccan basalt plateau. As water circulates through fractures in the basalt, it dissolves minerals that enrich the lake with sodium, carbonate, and bicarbonate ions. Evaporation further concentrates these dissolved salts, gradually giving the lake its distinctive chemical character.

An unusual hydrological pattern exists within the crater. Along the inner slopes of the rim, small freshwater springs emerge from the basaltic layers. These springs form a narrow belt of relatively fresh water around the margins of the lake, while the central basin remains strongly saline and alkaline.

This dual water system creates a unique ecological environment. Microorganisms capable of surviving in extreme chemical conditions — known as extremophiles — thrive within the lake. Because similar chemical environments may have existed on ancient Mars, Lonar has attracted considerable interest from researchers studying astrobiology and planetary habitability.

Occasionally, environmental changes can dramatically alter the lake’s appearance. In 2020, for example, the waters of Lonar Lake temporarily turned a striking pink hue due to the proliferation of salt-tolerant microorganisms and algae under conditions of increased salinity. Such episodes highlight the dynamic and sensitive chemistry of this remarkable crater lake.

---

Cultural Landscape

Long before scientists identified Lonar as the result of a meteorite impact, the crater was already embedded in the cultural and religious landscape of the region. Over the centuries, numerous temples were constructed along the inner slopes of the crater, many of them dating between the 10th and 13th centuries during the medieval period.

These temples, built in the distinctive stone architecture of the Deccan region, stand partly hidden among forests and basalt outcrops. Shrines dedicated to various Hindu deities, including Vishnu and Shiva, form a sacred network around the crater’s rim and interior pathways.

Local legend connects the site to the story of the demon Lonasura, who was slain here by the deity Vishnu. According to the traditional narrative, the impact depression itself is believed to mark the place where the demon fell, giving the crater its name.

In this way, Lonar represents an unusual convergence of mythology, sacred geography, and planetary science — a place where ancient storytelling and modern geology describe the same landscape through very different lenses.

Comparative Perspective: Lonar Among World Impact Craters

Impact craters occur across the Earth’s surface, but each forms within different geological environments. Comparing Lonar with other well-known impact craters helps illustrate why it occupies a special place in planetary geology.

While many terrestrial craters formed in sedimentary or crystalline rocks, Lonar is one of the very few confirmed impact craters created entirely within basaltic volcanic rock. This makes it particularly valuable for understanding how impacts behave in volcanic terrain similar to that found on the Moon and Mars.

Crater	Location	Diameter	Age	Target Rock Type
Lonar	India	1.8 km	~50,000 years	Basalt (Deccan Traps)
Barringer (Meteor Crater)	USA	1.2 km	~50,000 years	Sedimentary rock
Pingualuit	Canada	3.4 km	~1.4 million years	Crystalline shield rock

Although similar in age to the famous Barringer Crater in Arizona, Lonar differs significantly in geological context. Its formation in layered basalt allows scientists to study impact processes in volcanic terrain, providing insights that are relevant for interpreting craters on other planetary bodies.

---

Beyond Lonar: The Possible Kaveri Impact Structure

Lonar remains the only clearly confirmed meteorite impact crater formed in basaltic rock within India. However, geological research has suggested the possibility of another impact structure hidden beneath sediments along India’s eastern continental margin.

Geophysical surveys conducted in the offshore Cauvery Basin have identified a large circular feature buried beneath thick layers of sediment. Some researchers interpret this structure as a possible ancient meteorite impact site, commonly referred to as the Kaveri structure.

Unlike Lonar, this feature is not visible at the surface. It lies concealed beneath sedimentary deposits and has been identified only through seismic and geophysical data. Because of this, its origin remains uncertain.

If future studies confirm an impact origin, the Kaveri structure would represent another significant example of extraterrestrial collision within the Indian subcontinent. For now, however, Lonar remains the most clearly preserved and scientifically studied impact crater in the region.

---

Lonar and Mars: A Natural Planetary Analogue

Because Lonar formed entirely within basaltic rock, it provides a valuable terrestrial analogue for impact craters found on the Moon and Mars. Large regions of these planetary bodies are covered by ancient basaltic lava plains, similar in composition to the Deccan Traps of India.

This geological similarity allows scientists to study impact processes in basalt under real field conditions. Features such as crater morphology, ejecta distribution, impact glass formation, and shock-altered minerals observed at Lonar help researchers interpret comparable structures seen in spacecraft images of Martian and lunar surfaces.

Planetary geologists have therefore used Lonar as a natural laboratory for understanding how meteorite impacts interact with volcanic terrain. Observations made here assist in deciphering crater formation processes on other worlds where direct sampling is far more difficult.

In this sense, Lonar represents more than a geological curiosity within India. It serves as a rare window through which scientists can investigate the dynamics of impacts across the rocky planets of our Solar System.

---

The Deccan Traps and Earth's Great Turning Point

The basalt plateau surrounding Lonar was created during the formation of the Deccan Traps, one of the largest volcanic provinces on Earth. Around 66 million years ago, enormous fissure eruptions released vast quantities of lava across western and central India, producing layer upon layer of basalt that eventually covered hundreds of thousands of square kilometres.

This period represents one of the most dramatic turning points in Earth’s biological history. At roughly the same time, a massive asteroid struck the region that is now the Yucatán Peninsula of Mexico, forming the Chicxulub crater. The impact is widely associated with the global extinction event that eliminated the dinosaurs and many other species at the end of the Cretaceous period.

Some researchers have proposed that these two phenomena — the Chicxulub impact and the Deccan volcanic eruptions — may have been connected. One hypothesis suggests that seismic energy generated by the asteroid impact could have influenced magma systems beneath the Deccan region, potentially intensifying or altering volcanic activity.

Although this relationship remains an active topic of geological debate, the coincidence of massive volcanism and a catastrophic asteroid impact highlights how multiple planetary-scale processes may have shaped the course of life on Earth.

Glossary

Basalt: A dark, fine-grained volcanic rock formed when lava cools rapidly at the Earth's surface. Basalt is the dominant rock of large volcanic plateaus such as the Deccan Traps and also forms extensive plains on the Moon and Mars. Because of its volcanic origin and mineral composition, basalt behaves differently from sedimentary rocks when subjected to meteorite impacts.

Impact Crater: A circular or elliptical depression created when a meteoroid, asteroid, or comet strikes the surface of a planetary body at extremely high velocity. The energy released during the collision excavates rock, generates shock waves, and may melt or vaporise portions of the target material.

Meteoroid: A small rocky or metallic body travelling through interplanetary space. When a meteoroid enters Earth’s atmosphere it produces a bright streak of light known as a meteor. If fragments survive the descent and reach the ground, they are called meteorites.

Meteorite: A fragment of a meteoroid that survives passage through Earth’s atmosphere and reaches the surface. Meteorites provide valuable information about the early Solar System because many originate from asteroids that formed billions of years ago.

Shock Metamorphism: Structural and mineralogical transformation of rocks caused by the intense pressure and temperature generated during a meteorite impact. These changes include fracturing, melting, and the formation of distinctive high-pressure minerals that serve as key evidence for identifying ancient impact structures.

Maskelynite: A glassy material produced when the mineral feldspar is subjected to extreme shock pressure during an impact event. Its presence is a diagnostic indicator of meteorite collisions and is commonly found in both terrestrial impact sites and lunar samples.

Breccia: A rock composed of angular fragments of other rocks that have been shattered and later cemented together. In impact craters, breccias often form when bedrock is violently broken apart during the collision and subsequently re-deposited within the crater.

Ejecta: Rock fragments, dust, and molten material blasted outward from a crater during the moment of impact. Ejecta may blanket the surrounding landscape, forming characteristic deposits that radiate outward from the crater rim.

Basaltic Plateau: A vast region covered by successive lava flows that have cooled into stacked layers of basalt. Such provinces are typically formed during large volcanic events known as flood-basalt eruptions. The Deccan Traps of India represent one of the largest basaltic plateaus on Earth.

Extremophile: A microorganism capable of surviving and thriving in extreme environments such as highly saline, alkaline, acidic, or high-temperature conditions. Extremophiles are of great interest to astrobiology because similar environments may exist on other planets or moons.

Astrobiology: An interdisciplinary field of science that studies the origin, evolution, distribution, and potential future of life in the universe. Researchers investigate extreme environments on Earth, such as the waters of Lonar Lake, to understand how life might survive on planets like Mars.

Planetary Analogue: A natural environment on Earth that resembles conditions found on another planetary body. Scientists study such sites to better interpret observations from spacecraft missions and to prepare for future exploration of the Moon, Mars, and other worlds.

Why Lonar Is One of the Best Preserved Impact Craters on Earth

Although meteorite impacts have occurred throughout Earth’s history, relatively few impact craters remain clearly visible today. Over geological time, processes such as erosion, tectonic activity, sedimentation, and vegetation gradually obscure or destroy many impact structures.

Lonar Crater is exceptional because it has survived with its distinct circular form largely intact. Several factors contribute to this remarkable preservation. First, the crater formed relatively recently in geological terms — most estimates place its age between 35,000 and 50,000 years. This means that the processes that gradually erase impact features have not yet significantly altered its original morphology.

Second, the crater lies within the stable basaltic plateau of the Deccan Traps. Basalt is a hard volcanic rock that resists erosion more effectively than many sedimentary formations. As a result, the crater rim and inner slopes have retained their structure with surprising clarity.

Another important factor is the region’s relatively gentle tectonic environment. Unlike areas affected by active mountain building or major faulting, the Deccan plateau has remained geologically stable for long periods of time.

Because of this combination of youth, durable rock, and tectonic stability, Lonar remains one of the best preserved simple impact craters on Earth. Its remarkably clear structure allows scientists to study the geometry of impact craters in basaltic terrain and provides valuable insights into similar craters observed on the Moon and Mars.

Epilogue

Lonar Crater reminds us that Earth is not an isolated world. From time to time, fragments of the Solar System intersect with our planet, striking its surface with immense energy and leaving behind craters that endure for tens of thousands of years.

Yet the story of Lonar begins even earlier, within the vast basalt landscapes of the Deccan Traps — ancient lava flows that reshaped the Indian subcontinent millions of years before the impact occurred. The crater therefore records the meeting of two great planetary forces: deep volcanic processes within Earth and a sudden collision from space.

Over millennia, rainwater filled the crater basin, life adapted to its unusual chemistry, and human communities built temples along its slopes. What began as a moment of cosmic violence gradually became part of a living landscape.

Today Lonar stands as both a geological archive and a reminder of Earth's connection to the wider universe — a place where the history of our planet briefly intersected with the wandering fragments of space.

Pavani and Chandrajyoti: Rare Scales in Film Music

---

Preface

Carnatic music possesses a vast melodic universe in which each raga represents a unique emotional and tonal landscape. While many ragas have become familiar through the classical concert stage and through South Indian cinema, a number of scales remain elusive, appearing only rarely in film compositions. Among these rare melodic entities is Pāvani, the forty-first Melakarta raga — a scale belonging to the intriguing and historically debated group of vivādi ragas.

Film composers, even the most accomplished among them, seldom venture into the vivādi territory. The closely spaced swaras in these ragas produce an inherent tonal tension that requires extraordinary melodic sensitivity to handle gracefully. Yet, when approached with imagination and musical insight, these ragas can yield astonishing emotional depth.

This essay explores one such remarkable intersection between classical Carnatic theory and cinematic composition — the rare appearance of the raga Pāvani and its janya derivative Chandrajyoti in South Indian film music. Through examples from Tamil and Malayalam cinema, we observe how master composers translated complex classical grammar into evocative musical storytelling.

Pāvani and Chandrajyoti: Rare Scales in South Indian Film Music

Carnatic music contains hundreds of ragas, many of which flourish in the classical concert tradition but appear only rarely in cinema. Among these is the fascinating Pāvani, the 41st Melakarta raga. Pāvani belongs to the group of vivādi ragas — scales that contain closely spaced swaras producing a distinctive tonal tension.

Because of these intervals, Pāvani possesses a mysterious and emotionally intense colour. The raga can evoke devotion, longing, spiritual yearning, and psychological unease at the same time. For this reason it is extremely rare in film music, where composers often prefer smoother melodic frameworks.

Yet when handled by a master composer, the raga can produce extraordinary expressive depth. Two remarkable cinematic examples appear in South Indian cinema — one in Tamil and one in Malayalam — both sung by K. J. Yesudas.

---

The Structure of Pāvani

Pāvani is a sampoorna melakarta raga, meaning all seven swaras occur in both ascent and descent.

Ārohaṇa (Ascending)

S R₁ G₁ M₂ P D₂ N₃ S

Avarohaṇa (Descending)

S N₃ D₂ P M₂ G₁ R₁ S

The distinctive colour of the raga arises from the proximity of R₁ (Shuddha Rishabham) and G₁ (Shuddha Gandharam). Their closeness produces the characteristic tension associated with vivādi ragas. Combined with M₂ (Prati Madhyamam) and N₃ (Kākali Nishadam), the raga produces a luminous yet slightly unsettling sonic atmosphere.

---

---

The Challenge of Vivādi Swaras

In Carnatic music theory, certain swara combinations are described as vivādi — intervals whose close proximity produces a distinctive tonal friction. In the Melakarta scheme, ragas numbered 39 to 44 belong to this category. Their swara configurations place notes such as R₁ and G₁ or D₁ and N₁ extremely close together, creating a sound that can easily appear harsh if not handled with great care.

For centuries, many musicians regarded these ragas as theoretically interesting but aesthetically difficult. As a result, they were rarely explored in compositions or performances. Only highly skilled composers could transform these seemingly unstable intervals into melodic beauty.

When a composer successfully shapes a musical phrase within a vivādi raga, the result is striking: a soundscape that feels simultaneously luminous, tense, and deeply expressive. It is precisely this rare expressive colour that makes Pāvani so compelling when it appears in film music.

Pāvani in Tamil Cinema — “Paartha Vizhi”

One of the most striking cinematic uses of Pāvani appears in the song “Paartha Vizhi” from the 1991 Tamil film Gunaa. The music was composed by Ilaiyaraaja, sung by K. J. Yesudas, with lyrics by Abhirami Pattar & Vaali.

Within the narrative of the film, the song reflects the fragile psychological world of the protagonist. Devotion, obsession, and longing merge in the character’s mind, and Pāvani’s tense tonal structure mirrors this emotional landscape with remarkable precision.

“Paartha Vizhi” remains widely regarded as the only Tamil film song clearly structured around the raga Pāvani.

---

---

Pāvani in Telugu Cinema — “Shambhavi”

The raga Pāvani also appears in the Telugu version of Gunaa, in the song “Shambhavi”, rendered by S. P. Balasubrahmanyam. This version retains the core melodic structure of Paartha Vizhi while adapting its lyrical and vocal expression to the Telugu cinematic context.

---

Ilaiyaraaja’s Subtle Revelation of Pāvani

One of the most remarkable aspects of Ilaiyaraaja’s composition in Paartha Vizhi lies in the way the raga is revealed gradually rather than through an overt demonstration of the scale. Instead of presenting a straightforward ascending or descending passage, the composer introduces carefully shaped melodic fragments that highlight the raga’s identity.

Particularly significant is the delicate movement between R₁ and G₁, a defining characteristic of the raga. These notes, placed almost side by side in pitch, create the unmistakable vivādi colour. In the song, this phrase appears fleetingly within the melodic contour, quietly affirming the raga’s structure while maintaining the emotional flow of the composition.

Such treatment exemplifies Ilaiyaraaja’s profound understanding of Carnatic grammar combined with cinematic sensibility. The listener experiences the emotional effect of the raga without necessarily recognising the theoretical framework underlying it.

Characteristic Pāvani Phrases in the Composition

Ilaiyaraaja reveals the raga through subtle melodic phrases rather than presenting the scale directly.

Characteristic phrase

S R₁ G₁ M₂ – G₁ R₁ S

This phrase emphasises the crucial interaction between R₁ and G₁, producing the unmistakable vivādi tension that defines the raga.

Upper register movement

P D₂ N₃ S – N₃ D₂ P

Here the upper tetrachord unfolds before resolving gently downward, allowing the listener to sense the complete structure of the raga within the flow of the melody.

Pāvani in Malayalam Cinema

The rare melodic character of Pāvani has also appeared once in Malayalam film music. In the 1999 Malayalam film Devadasi, composer Sharreth crafted the song “Chalal Chanchala”, a composition structured on this challenging melakarta raga.

The piece was rendered by K. J. Yesudas, with lyrics written by S. Ramesan Nair. Much like its Tamil counterpart Paartha Vizhi, the composition carefully preserves the raga’s distinctive swara relationships while adapting them to a cinematic melodic structure.

To date, this remains the only known Malayalam film song explicitly structured on the Pāvani scale, making it a remarkable and rare instance of a vivādi melakarta entering mainstream film music.

While Pāvani itself remains extremely rare in cinema, one of its janya ragas—Chandrajyoti—has also made a brief but fascinating appearance in Tamil devotional film music.

Chandrajyoti — A Janya of Pāvani

A derivative of Pāvani is the janya raga Chandrajyoti. Like many janya ragas, it reshapes the parent scale while retaining part of its tonal flavour.

Common scale used in Carnatic music

Ārohaṇa

S R₁ M₂ P N₂ S

Avarohaṇa

S N₂ P M₂ R₁ S

This pentatonic structure removes several notes of the parent melakarta but preserves its subtle tension and luminous tonal colour.

---

Chandrajyoti in Tamil Devotional Cinema

One of the rare cinematic examples of Chandrajyoti appears in the 1997 devotional film Ezhumalaiyan Mahimai. The song “Nanmai Nalgum”, composed by Ilaiyaraaja, stands as one of the very few film compositions associated with this raga.

The composition demonstrates Ilaiyaraaja’s ability to translate complex classical ragas into emotionally resonant devotional music without losing their identity.

---

The Historical Curiosity of Vivādi Ragas

Pāvani belongs to the Melakarta group numbered 39–44, traditionally called the vivādi ragas. These scales contain intervals that were historically considered difficult to handle aesthetically.

For centuries many musicians avoided them, believing the tonal tension could easily sound harsh if not treated with great care. Only composers with deep melodic insight were able to reveal their beauty.

Whenever a composer successfully employs a vivādi raga — whether in classical compositions or film music — it becomes a notable artistic achievement. The rare cinematic appearances of Pāvani and its janya Chandrajyoti therefore stand as fascinating examples of how even complex Carnatic scales can become powerful vehicles of emotion and storytelling.

Part of an ongoing exploration of rare Carnatic ragas in South Indian film music.

The rarity of Pāvani in cinema raises an interesting question: why do composers seldom explore this raga despite its expressive potential?

Why Pāvani Is Almost Never Used in Cinema

Despite being a full sampoorna melakarta raga, Pāvani is extraordinarily rare in both classical compositions and film music. The reason lies in its membership within the vivādi melakarta group, specifically ragas numbered 39 to 44 in the Carnatic system.

These ragas contain swaras that lie extremely close to one another in pitch. In Pāvani, the pairing of R₁ (Shuddha Rishabham) and G₁ (Shuddha Gandharam) produces a narrow interval that can easily sound tense or unstable if not handled with great melodic care. Similarly, the presence of M₂ (Prati Madhyamam) alongside these lower swaras further intensifies the raga’s tonal colour.

Historically, many musicians regarded vivādi ragas as theoretically valid but aesthetically difficult. Earlier generations of performers often avoided them in concerts because their delicate intervals required exceptional precision in intonation and phrasing. Without careful treatment, the raga could quickly lose its identity and appear musically awkward.

For film composers, the challenge is even greater. Cinema demands melodies that are immediately accessible to listeners, capable of conveying emotion within seconds. Ragas with smoother scalar movement—such as Kalyani, Mohanam, or Charukesi—naturally lend themselves to this requirement.

Pāvani, however, requires subtle melodic handling and deliberate phrase construction. A composer must reveal the raga gradually through characteristic movements rather than straightforward scalar passages. This level of compositional discipline is rarely compatible with the time constraints and commercial expectations of film music.

It is therefore not surprising that only a handful of composers have ventured into this melodic territory. When such attempts succeed—as in Ilaiyaraaja’s remarkable handling of Pāvani in Paartha Vizhi—the result stands out as an extraordinary fusion of classical sophistication and cinematic expression.

In this sense, the rare appearance of Pāvani in film music is not a limitation but a testament to the raga’s demanding beauty. Each successful composition becomes a small but significant milestone in the continuing dialogue between Carnatic tradition and modern musical storytelling.

Epilogue

The rare cinematic appearances of Pāvani and Chandrajyoti illustrate a fascinating dialogue between classical tradition and film music. These ragas, once considered too difficult or unstable for widespread melodic use, found renewed life through the imagination of modern composers.

When a raga from the vivādi group enters film music, it does more than merely decorate a melody; it brings with it centuries of theoretical debate, aesthetic exploration, and musical daring. In this sense, such compositions serve as bridges between the rigorous grammar of Carnatic music and the emotional immediacy of cinema.

Through works such as Paartha Vizhi and the devotional composition Nanmai Nalgum, listeners are offered a rare glimpse into how even the most complex melodic structures can become powerful vehicles for storytelling, devotion, and psychological expression.

---

Coda

In the immense landscape of South Indian film music, the appearance of a rare raga can feel like a fleeting astronomical event — brief, luminous, and unforgettable. Pāvani and its janya Chandrajyoti remind us that cinema, at its finest, does not merely borrow from classical music; it becomes a space where ancient melodic ideas find new resonance in the modern imagination.

---

---

Closing Reflections

The journeys of Pāvani and its luminous janya raga Chandrajyoti through the landscape of film music reveal how even the most complex Carnatic scales can find expression beyond the classical concert stage. Though separated by context—one emerging in the psychological intensity of Gunaa, another in Malayalam cinema, and yet another in Tamil devotional music—these rare appearances demonstrate the remarkable adaptability of raga grammar when placed in the hands of imaginative composers.

Such compositions remind us that cinema, at its finest, does not merely borrow from classical tradition but expands its emotional vocabulary. When a demanding vivādi raga like Pāvani is shaped into a memorable melody, it becomes more than a technical achievement; it becomes a bridge between rigorous musical theory and the shared emotional experience of listeners.

In that sense, these few songs stand as quiet but enduring landmarks—moments where the intricate beauty of Carnatic music briefly illuminates the wider world of film music.

Glossary of Musical Terms

Melakarta
A parent scale in Carnatic music consisting of seven swaras (notes) in both ascending and descending order. The Carnatic system contains 72 melakarta ragas, from which many derived ragas originate.

Janya Raga
A raga derived from a melakarta parent scale. Janya ragas may omit certain notes, rearrange swara sequences, or emphasise characteristic melodic phrases.

Vivādi Swaras
Notes that lie very close to each other in pitch, creating a tense or dissonant interval. Ragas containing such swaras are called vivādi ragas and require careful melodic handling.

Sampoorna Raga
A raga that employs all seven swaras in both the ascending (ārohaṇa) and descending (avarohaṇa) scales.

Ārohaṇa
The ascending sequence of notes in a raga, describing how the scale rises from the tonic (Sa).

Avarohaṇa
The descending sequence of notes in a raga, describing how the scale returns to the tonic.

Swaras
The musical notes used in Indian classical music: Sa, Ri, Ga, Ma, Pa, Dha, and Ni. Each swara may have multiple variants depending on the raga.

Prati Madhyamam (M₂)
The sharpened version of the fourth note (Ma) in the Carnatic scale. Its presence often gives ragas a bright or intense tonal colour.

Shuddha Rishabham (R₁)
A low variant of the second note (Ri) in Carnatic music. When paired closely with certain Gandharam notes it produces vivādi tension.

Shuddha Gandharam (G₁)
A low variant of the third note (Ga). Its proximity to R₁ is one of the defining characteristics of ragas like Pāvani.

Kakali Nishadam (N₃)
The highest variant of the seventh note (Ni), often contributing a bright and intense melodic colour.

Abirami Pattar
An 18th-century Tamil Hindu saint-poet and devotee of Goddess Abirami (a form of Parvati) associated with the temple at Thirukkadaiyur in Tamil Nadu. He is most renowned for composing the devotional hymn Abirami Anthathi, a poetic work consisting of one hundred verses arranged in the classical anthathi style, where each verse begins with the ending word of the previous verse.

Vaali (T. S. Rangarajan)
One of the most celebrated lyricists in Tamil cinema. Over a career spanning more than five decades, Vaali wrote thousands of film songs noted for their poetic imagination, literary references, and adaptability to a wide range of musical styles. His lyrics for songs such as Paartha Vizhi from the film Gunaa demonstrate his ability to combine philosophical depth with cinematic expression.

Ilaiyaraaja
A legendary Indian composer widely regarded as one of the greatest music directors in South Asian cinema. Known for his extraordinary synthesis of Western orchestration and Indian classical traditions, Ilaiyaraaja has composed thousands of songs across several languages. His works frequently incorporate complex Carnatic ragas and sophisticated harmonic structures while remaining accessible to a broad audience.

K. J. Yesudas
Kattassery Joseph Yesudas is one of India’s most revered playback singers and classical vocalists. Celebrated for his rich tonal quality and impeccable diction, he has recorded thousands of songs in multiple Indian languages. Yesudas is equally respected in both Carnatic classical music and film music, and his voice has brought many raga-based compositions to a wide audience.

Sharreth
An Indian composer, singer, and music director known for his work in Malayalam, Tamil, and Telugu cinema. Trained in classical music, Sharreth often incorporates raga-based structures and traditional melodic elements into his film compositions, blending classical sensibilities with contemporary orchestration.

Carnatic Music
The classical music tradition of South India, characterised by a highly developed system of ragas (melodic frameworks) and talas (rhythmic cycles). Carnatic music emphasises melodic improvisation, intricate ornamentation known as gamakas, and compositions that combine musical structure with devotional poetry.

Ragam (Raga)
A melodic framework in Indian classical music that defines a specific set of notes, characteristic phrases, and emotional colour. Each raga possesses its own identity and grammar, guiding how melodies are created and developed in both classical and semi-classical compositions.

Swaram (Swara)
A musical note in Indian classical music. The basic swaras are Sa, Ri, Ga, Ma, Pa, Dha, and Ni. Variations of these notes create different tonal colours and form the basis of raga structures.

Melakarta System
The foundational framework of Carnatic music that organises the parent scales of the tradition. The system consists of 72 melakarta ragas, each containing seven swaras in both ascending (ārohaṇa) and descending (avarohaṇa) order. These parent scales serve as the source from which numerous derived ragas, known as janya ragas, emerge.

Vivādi Ragas (39–44 Group)
A distinctive group of melakarta ragas within the Carnatic system known for containing vivādi swaras—notes that lie extremely close to one another in pitch, creating a tense or dissonant tonal relationship. Melakarta ragas numbered 39 to 44, including Pāvani (41), belong to this category. Historically, these ragas were considered difficult to render melodically, and many musicians approached them cautiously. When handled skillfully, however, they reveal a striking and unique musical colour.

Raga Lakshana
The defining grammar and identity of a raga. Raga lakshana includes its scale (ārohaṇa and avarohaṇa), characteristic phrases, dominant notes, permitted ornamentations, and aesthetic mood. Together these elements distinguish one raga from another even when their scales appear similar.

Gamaka
Ornamental oscillations or embellishments applied to swaras in Carnatic music. Gamakas are essential for expressing the true character of a raga and often distinguish authentic raga rendering from a simple scale.

Tala
The rhythmic framework of a composition in Indian classical music. Talas organise musical time into repeating cycles of beats and subdivisions, forming the rhythmic foundation over which melodies are developed.
