Tallapaka Annamacharya (also popularly known as Annamayya)(22 May 1408 – 4 April 1503) was a 15th-century Hindu saint and the earliest known Indian musician to compose songs called sankirtanas in praise of the Lord Venkateswara, a form of Vishnu.He is the first known composer in carnatic music. The most famous composers of Carnatic music like Purandara Dasa, Kanaka Dasa also came after him. 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.Annamacharya is remembered for his saintly life, and is honoured as a great devotee of Vishnu by devotees and saintly singers.
He is believed to have been the creator avatar of Nandaka, the sword of Vishnu. He is widely regarded as the Andhra Pada kavitā Pitāmaha (Grandfather of Telugu song-writing).
