Revati is a rāgam in Carnatic music (musical scale of South Indian classical music). It is an audava rāgam (or owdava rāgam, meaning pentatonic scale). It is a janya rāgam (derived scale), as it does not have all the seven swaras (musical notes).
Revati is a symmetric rāgam that does not contain gāndhāram or dhaivatam. It is a pentatonic scale (audava-audava ragam[1][2] in Carnatic music classification – audava meaning 'of 5'). Its ārohaṇa-avarohaṇa structure (ascending and descending scale) is as follows (see swaras in Carnatic music for details on below notation and terms):
This section covers the theoretical and scientific aspect of this rāgam.
In Japanese/Western music Revati corresponds to Insen scale
Graha bhedam
Revati's notes when shifted using Graha bhedam, yields 2 other pentatonic rāgams, namely, Shivaranjani and Sunadavinodini. Graha bhedam is the step taken in keeping the relative note frequencies same, while shifting the shadjam to the next note in the rāgam. See Graha bhedam on Shivaranjani for more details and an illustration.
Scale similarities
Madhyamāvati is a rāgam which has the chathusruthi rishabham in place of the shuddha rishabham. Its ārohaṇa-avarohaṇa structure is S R2 M1 P N2 S : S N2 P M1 R2 S
