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).
Structure and Lakshana
Revati is a symmetric rāgam that does not contain gāndhāram or dhaivatam. It is a pentatonic scale (audava-audava ragam 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):
(notes used in this scale are shuddha rishabham, shuddha madhyamam, panchamam, kaisiki nishadham)
Revati is considered a janya rāgam of Ratnangi, the 2nd Melakarta rāgam, though it can be derived from other melakarta rāgams, Vanaspati, Hanumatodi, Natakapriya, Vakulabharanam or Chakravakam, by dropping both gāndhāram and dhaivatam.
Revati rāgam lends itself for elaboration and exploration and has many compositions. Here are some popular kritis composed in Revati.
- Jagannatha anatharakshaka by Subba Rao
- Nanati badhuku by Annamacharya
- Mahadeva siva sambho
- Bho sambho
Lalgudi Jayaraman has also composed a melodious Thillana in this rāgam.
This section covers the theoretical and scientific aspect of this rāgam.
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.
