Ganamurti

Ganamurti scale with Shadjam at C

It is the 3rd rāgam in the 1st chakra Indu. The mnemonic name is Indu-Go. The mnemonic phrase is sa ra ga ma pa dha nu.[1] 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 R₁ G₁ M₁ P D₁ N₃ Ṡ[lower-alpha 1]
• avarohaṇa: Ṡ N₃ D₁ P M₁ G₁ R₁ S[lower-alpha 2]

The notes used in this scale are shuddha rishabham, shuddha gandharam, shuddha madhyamam, shuddha dhaivatham, kakali 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 shuddha madhyamam equivalent of Jhalavarali, which is the 39th melakarta.

Gānasāmavarāḷi is the 3rd Melakarta in the original list compiled by Venkatamakhin. The notes used in the scale are the same, but the ascending scale is different. It is a shadava-sampurna raga (6 notes in ascending scale, while full 7 are used in descending scale).[3]

• ārohaṇa: S R₁ M₁ P D₁ N₃ Ṡ[lower-alpha 3]
• avarohaṇa: Ṡ N₃ D₁ P M₁ G₁ R₁ S[lower-alpha 4]

This section covers the theoretical and scientific aspect of this rāgam.

Ganamurti's notes when shifted using Graha bhedam, yields 2 other melakarta rāgams, namely, Vishwambari and Shamalangi. 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 Ganamurti.
