Taḷḷapāka Annamācārya (or Annamayya) (May 22, 1408 – February 14, 1503) was a 15th-century Hindu saint and is the earliest known Indian musician to compose songs called sankirtanas in praise of the god Venkateswara, a form of Vishnu. The musical form of the keertana songs that he composed, which are still popular among Carnatic music concert artists, have strongly influenced the structure of Carnatic music compositions.
