Revati (raga)
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). In Hindustani music a raga that closely resembles Revati is Bairagi Bhairav. It is said to evoke Karuṇa rasa (pathos). This scale has also been used in chanting Vedas. 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  structure (ascending and descending scale) is as follows (see swaras in Carnatic music for details on below notation and terms):
