What is "konnakol"

Konnakol (also spelled Konokol, Konakkol) is the art of performing percussion syllables vocally in South Indian music, the Carnatic music ( South Indian classical) performance art of vocal percussion. Konnakol is the spoken component of solkattu, which refers to a combination of konnakol syllables spoken while simultaneously counting the tala (meter) with the hand. It is comparable in some respects to bol in Hindustani music, but allows the composition, performance or communication of rhythms. Sri Thetakudi Harihara Subash Chandran is a well-known proponent.
