The Voice Behind the Mask

Imagine a night-long performance lit by the warm glow of a bronze lamp. On stage, a towering figure in vivid green-and-red make-up embodies Lord Krishna — eyes rolling, fingers weaving elaborate mudras that speak a wordless language. The dancer does not utter a single word. Yet the air is thick with song, rhythm, and emotion. Where is this music coming from?

Step back into the shadows of the stage and you will find them: two singers seated beside the percussion ensemble, microphone-less in the old tradition, their voices carrying the poetry, the narrative, the very soul of what you are watching. This is the music of Kathakali — invisible to the uninitiated, and yet absolutely central to everything happening in front of you.

Roots in the Temple Step

To understand Kathakali music, you first need to understand Sopana Sangeetham — the ancient musical tradition that gave birth to it. Sopana, meaning "the step," refers to the sacred flight of stairs leading to a Kerala temple's inner sanctum. For centuries, devotional songs were sung on these steps as offerings to the deity, gradually crystallising into a distinct musical style — slower and more meditative than Carnatic music, rooted in a handful of evocative Kerala-specific ragas, and deeply tied to bhakti (devotion) rather than virtuosic display.

Kathakali's origins trace back to the 17th century when Kottarakkara Thampuran created Ramanattam — a dramatic retelling of the Ramayana in eight parts — building on the earlier ritual form of Krishnanattam. As this art form evolved into what we know as Kathakali, it inherited the Sopana musical tradition as its backbone. The music moved with the drama, and Sopana Sangeetham became the voice of the stage.

Over time, particularly through the influence of the Kerala Kalamandalam (the premier institution for classical Kerala arts, founded in 1930), Kathakali music absorbed elements of classical Carnatic music — more ornamental passages, a wider raga palette — without ever abandoning its Sopana roots. The result is a tradition that sits at a fascinating crossroads: distinctly Keralite in flavour, yet deeply classical in its architecture.

How Kathakali Music Works

Unlike most classical Indian dance forms where the performer herself is also the vocalist, Kathakali separates the dancer and the singer completely. Two vocalists — the Ponnani (lead singer) and the Shinkiti (supporting singer) — sit to the side of the stage. They sing the aattakatha, the libretto of the play, carrying the narrative forward while the dancers enact it entirely through gesture, expression, and movement.

The vocal style is demanding and distinctive. Singers use sixty different ragas and six talas, many of which are specific to the Sopanam tradition — ragas like Samanthamalahari, Puranceru, Paati, Huseni, and Indalam that are rarely heard elsewhere. The singing is marked by a deliberate, sustained quality: notes are held, stretched, and shaped with tremendous care. There is a "plain note rendition" style (known as the Sopanam style) that forms the bedrock of performance, and onto this, more ornate Carnatic-influenced passages are layered for emotional effect.

The percussion section is no less essential. The Chenda — a cylindrical drum of great power, played with curved sticks — drives the intensity of battle scenes and dramatic climaxes. The Maddalam, a barrel-shaped drum worn at the waist, provides the rhythmic foundation. And the Idakka, an elegant hourglass drum, enters softly when female characters or lyrical moments call for tenderness. Together, they create a sonic world that the singer inhabits.

The Masters Who Shaped the Sound

The 20th century brought extraordinary musicians to the Kathakali stage, and none was more influential than Kalamandalam Neelakantan Nambisan (1920–1985). A student of the legendary Mundaya Venkitakrishna Bhagavatar, Nambisan transformed Kathakali music almost single-handedly — his weighty, part-nasal vocal style moved the tradition from its original Sopana base towards a more ornate, bhava-rich approach. His recordings remain touchstones, and his disciples went on to define the art for subsequent generations.

Among those disciples, Kalamandalam Gangadharan and Kalamandalam Sankaran Embranthiri stand out as two of the most celebrated voices of the later 20th century. Embranthiri, in particular, is remembered for a voice of rare authority and depth — his renditions of pieces from Nalacharitham and Utharaswayamvaram are considered definitive. Kalamandalam Venmani Haridas, who often performed as Ponnani to Embranthiri's Shinkiti (and vice versa), brought an almost meditative quality to the vocal line that audiences found deeply moving.

The northern and southern schools of Kathakali music each carry their own traditions and lineages, and the Kalamandalam at Thrissur has been the crucible where much of the modern northern style was refined and transmitted.

✦ Did You Know?

• Before every Kathakali performance, a percussion prelude called Keli is played at sunset — audible from a distance, it was historically the only form of publicity available to announce that a performance would take place that night.

• More than five hundred Kathakali plays (aattakathas) have been written, most of them before the 20th century. Yet only about four dozen are regularly performed today — the rest survive in manuscript but have fallen out of the living repertoire.

• The Idakka drum has a specific role in Kathakali: it is brought out only for female characters and lyrical, gentle passages. Its muted, melodious tones are considered the sonic equivalent of femininity within the performance tradition.

A Living Tradition

What makes Kathakali music remarkable is precisely the tension it holds together. It is music in the service of drama — never purely concert music, never purely devotional music — and yet it demands the full attention and skill of a concert musician to render properly. The Ponnani must know the drama intimately enough to guide the dancer's timing with a glance; the percussionists must be sensitive enough to shift from thunderous intensity to near-silence in a breath.

Today, younger musicians trained at the Kalamandalam and institutions like the Margi are carrying this tradition forward, and contemporary audiences — both in Kerala and abroad — are discovering Kathakali music as a listening art in its own right, separate from the stage spectacle that originally framed it.

There is a beautiful paradox at the heart of Kathakali: the most visible art form in Kerala — all towering head-dresses and blazing colour — is animated, at its core, by something entirely invisible. The music. The next time you watch a Kathakali performance, close your eyes for a moment and just listen. What you hear is centuries of devotion, carried in a human voice, offered in the dark.
