Thayambaka or tayambaka is a type of solo chenda performance that developed in the south Indian state of Kerala, in which the main player at the centre improvises rhythmically on the beats of half-a-dozen or a few more chenda and ilathalam players around.
Thayambaka, believed to have flourished during the feudal era, spans an average of 90 minutes. It begins at a slow pace before scaling on to a medium tempo and eventually culminating in high, frenzied speed. It has a skeletal pattern on which the performance progresses, but the main performer has the liberty to improvise and innovate to showcase his grip of rhythm, finesse of techniques and cerebral brilliance. In fact, thayambaka is one chenda concert that allows maximum individual freedom to the main player. Thayambaka, like panchavadyam or most chenda melams, is primarily a temple art, but it is also performed outside shrines—like on proscenium stages, open fields or pageantry grounds.
