Kalyanavasantam (also written as kalyanavasantham) is a rāgam in Carnatic music (musical scale of South Indian classical music). It is a janya rāgam (derived scale) from the 21st melakarta scale Keeravani. It is a janya scale, as it does not have all the seven swaras (musical notes) in the ascending scale. It is a combination of the pentatonic scale Chandrakauns of Hindusthani music and the sampurna raga scale Keeravani.
