In a Bharatanatyam performance, several musicians contribute to the soundscape: the vocalist who sings the compositions, the violinist who provides melodic support, the flautist who adds colour, and the nattuvangam player who keeps the tala cycle with cymbals and calls out the rhythmic syllables. But the heartbeat of the entire ensemble — the anchor of rhythm, the partner of the dancer's feet — is the mridangam.
An Ancient Instrument
The mridangam is a double-headed barrel drum, with one end producing a high-pitched, tight sound and the other a lower, resonant bass. It is played with the hands — no sticks. Both heads are made from layers of tightly stretched skin, with a permanent black circle (called the syahi) on the right head made from a paste of rice flour, iron oxide, and other ingredients. This patch is what gives the mridangam its distinctive, tunable tone — a refinement described in the Natya Shastra and refined over two millennia of performance practice.
The Dialogue Between Feet and Drum
In a Bharatanatyam recital, the relationship between the dancer and the mridangist is one of the most intimate in all of performing arts. During nritta passages — pure dance without narrative — the dancer's feet and the drum are in constant rhythmic conversation. The dancer performs sollukattus (rhythmic syllable phrases) with her feet, and the mridangist mirrors, responds, or elaborates. In the korvai and tirmana sections — rhythmic climaxes that resolve on the sam (the first beat of the cycle) — dancer and drummer must arrive together with mathematical precision. When this alignment is perfect, the effect is electric for the audience.
The Nattuvangam Connection
The nattuvangam — the small brass cymbals played by the conductor of the dance — is the link between the mridangist and the dancer. The nattuvangam player (the nattuvanar) keeps the primary beat, calls out the sollukattus, and signals transitions in the composition. The mridangist takes their cues from the nattuvanar and from the dancer's footwork. A good mridangist watches the dancer constantly, anticipating her movements, supporting her phrasing, and lending weight and drama to key moments in the choreography.
Appreciating the Mridangam as an Audience Member
Audiences at Bharatanatyam performances often focus entirely on the dancer. But attending to the mridangist unlocks a second layer of the performance. Watch how the mridangist builds intensity through the varnam — the long central piece. Notice how the patterns grow in complexity, how the cross-rhythms (called kuraippu) create tension before resolving back to the main beat, and how the mridangist celebrates a well-executed korvai with a small flourish of their own. The mridangam is not accompaniment. It is co-authorship.
