Kosalam

It is called Kusumākaram in Muthuswami Dikshitar school of Carnatic music.

The mnemonic phrase is sa ru gu mi pa dhi nu.

[2] Its ārohaṇa-avarohaṇa structure (ascending and descending scale) is as follows (see swaras in Carnatic music for details on below notation and terms): (the scale's notes are shatsruthi rishabham, antara gandharam, prati madhyamam, chathusruthi dhaivatham, kakali nishadham) Kosalam is a melakarta rāgam and hence, by definition, it is a sampoorna rāgam (it has all seven notes in ascending and descending scale).

The song Paarthene from Mookuthi Amman by Girishh Gopalakrishnan is also based on Kosalam.

Kosalam's notes when shifted using Graha bhedam, yields 3 other melakarta rāgams, namely, Keeravani, Hemavati and Vakulabharanam.
