Bharatanatyam, whose antiquity is well established, is the most popular of Indian dances, which said to be originated in Thanjavoor (Tanjore) of Tamil Nadu. Bharatanatyam is a purest form of classical dance

These three concepts comes into play in Bharatnatayam Bhava, Raga and Thaala.

Bharata Natyam dance has been handed down through the centuries by dance teachers (or gurus) called nattuwanars and the temple dancers, called devadasis. In the sacred environment of the temple these familes developed and propagated their heritage.

The music of Bharatanatyam is based on Carnatic classical music. The chief musical instruments in Bharata Natyam are the 'Mridangam' and a pair of cymbals. Sometimes Veena, Violin, Ghatam and Flute are also used.

The costumes of the dancer are very gorgeous, which consists of 'Paijama' or Dhoti and jacket of Kanchipuram silk and Banaras silk. Women wear a tight fitting 'Choli' or bodice of the same colour and material as the dhoti.
