 Rhythm (percussion) layer: improvised, complex, rhythmic patterns based on a tala (metric cycle); led by the principal accompanying percussionist, playing a mridangam (double-headed Indian drum), sometimes with subordinate percussion instruments such as kanjira (tambourine), ghatam (clay pot), or morsang (Jew's or jaw's harp).
