The notes chathusruthi rishabham, sadharana gandharam, shuddha madhyamam, shatsruthi dhaivatham and kakali nishadham are used in this scale. As it is a melakarta, by definition it is a sampoorna rāgam (has all seven notes in ascending and descending scale). It is the shuddha madhyamam equivalent of Neetimati, which is the 60th melakarta scale. Janya rāgams

This section covers the theoretical and scientific aspect of this rāgam. Varunapriya's notes when shifted using Graha bhedam, yields a minor melakarta rāgam, namely, Ragavardhini. Graha bhedam is the step taken in keeping the relative note frequencies same, while shifting the shadjam to the next note in the rāgam. For further details and an illustration refer Graha bhedam on Ragavardhini. Notes
