Known for their complex structure, varnams are a fundamental form in Carnatic music. All varnams consist of lyrics, as well as swara passages, including a "pallavi", an "anupallavi", "muktaayi swaras", a "charanam", and "chittaswaras". There are different types of varnams, such as taana varnam, pada varnam, daru varnam and ragamalika varnam. They also come different taalams (beat cycles). Though the most popular varnams are in Aadi and Ata taalas, there are a number of varnams in other talas as well (e.g., jampa tala, triputa tala, matya talam, roopaka talam, etc).
