Keeravani is the 21st melakarta ragam in the 72 melakarta padhathi of Carnatic music, and is the 3rd ragam in the 4th chakra named Veda. It has several janya ragams (derived ragams), including Chandrika, Hamsavahini and Kalyana Vasantham.
 
In this Sampoorna ragam, the Ri, Ma and Ni are rendererd as jiva swaras and also as ragachaya swaras. When singing the alapana for this ragam, all swaras are usually rendered with gamakas. Keeravani also happens to be the shuddha madhyamam equivalent of the raga, Simhendramadhyamam.
