Main feature if Thillana is brick and attractive music. Thillanas are sung in the end of either music or dance performance.
Thillana includes Pallavi, Anupallavi and Charanam. Is starts from eye movements, followed by several Mai Adavus (featuring elaborate body movements) set to Pallavi. After Mai adavu several korvais (sets of adavus) are performed set to Pallavi and Anupallavi.
The movements here are leisurely. In the Shabdam, emotions are withheld at the beginning; thereafter, when the dancer has clarified herself, they are released in a measured and disciplined manner.
Usi adavu is another feature of Thillana, when dancer covers the stage by quick and fast sequence of movements. Thillana is Nritta item, but there is always one-two line slokam in the end when dancer performs abhinaya (Addressing the deity last time before to conclude the program).
