Thanjavur Quartet were four brothers, Chinnayya, Ponnayya, Sivanandam and Vadivelu, who lived during the early 19th century and contributed to the development of Bharatanatyam and Carnatic music.
They excelled in the art of Bharatanatyam. The brothers were employed in the courts of the Maratha King Serfoji II at Thanjavur initially, and then moved to Travancore to the court of Swathi Thirunal. The Tanjore brothers gave the actual form of the recent day repertoire of Bharatanatyam - The Margam. The eldest of all the four brothers, Chinnayya moved to the Royal Court of Mysore during the rule of Krishnaraja Wadiyar III and composed many songs in praise of him. While his famous Thillana in Kapi Raga and Adi Tala is in praise of the Mysore King Sri Chamarajendra Wadiyar X and is one the most popular compositions.
