Raga Hemavati or Hemavathi
Hemavati is a raga in Carnatic music (musical scale of South Indian classical music). It is the 58th Melakarta ragam in the 72 melakarta ragam system of Carnatic music.
It is called Simharavam or Deshi Simharavam 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.
Hemavati scale with Shadjam at C. Hemavati is the 4th ragam in the 10th chakra Disi. The mnemonic name is Disi-Bhu. The mnemonic phrase is sa ri gi mi pa dhi ni. Its aroha?a-avaroha?a structure (ascending and descending scale) is as follows (see swaras in Carnatic music for details on below notation and terms):
Aroha?a : S R2 G2 M2 P D2 N2 S
Avaroha?a : S N2 D2 P M2 G2 R2 S
As it is a melakarta ragam, by definition it is a sampoorna ragam (has all seven notes in ascending and descending scale). It is the prati madhyamam equivalent of Kharaharapriya, which is the 22nd melakarta.
Hemavati has a few minor janya raqgams (derived scales) associated with it. See List of janya ragams to view all ragams associated with Hemavati.
Hemavati's notes when shifted using Graha bhedam, yields 3 other major melakarta ragams, 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 ragam. For further details and an illustration refer Graha bhedam on Keeravani.
