Hemavati (pronounced hēmavati) is a rāgam in Carnatic music (musical scale of South Indian classical music). It is the 58th Melakarta rāgam in the 72 melakarta rāgam system of Carnatic music.
It is called Simhāravam or Deshi Simhāravam in Muthuswami Dikshitar school of Carnatic music. It is beloved especially of nadaswaram vidwans. It is said to be borrowed into Hindustani music from Carnatic music, especially with instrumentalists.

It is the 4th rāgam in the 10th chakra Disi. The mnemonic name is Disi-Bhu. The mnemonic phrase is sa ri gi mi pa dhi ni. Its ārohaṇa-avarohaṇa structure (ascending and descending scale) is as follows (see swaras in Carnatic music for details on below notation and terms):ārohaṇa: S R2 G2 M2 P D2 N2 S
avarohaṇa: S N2 D2 P M2 G2 R2 S
(the notes for this scale are chathusruthi rishabham, sadharana gandharam, prati madhyamam, chathusruthi dhaivatham, kaisiki nishadham)
As it is a melakarta rāgam, by definition it is a sampoorna rāgam (has all seven notes in ascending and descending scale). It is the prati madhyamam equivalent of Kharaharapriya, which is the 22nd melakarta.

This section covers the theoretical and scientific aspect of this rāgam.
Hemavati's notes when shifted using Graha bhedam, yields 3 other major melakarta rāgams, namely, Keeravani, Vakulabharanam and Kosalam. 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 Keeravani.
