The scales of Kamaas (alt spelling : Kamas, Khamas) are as follows :
Aarohanam (Ascending) : S M1 G3 M1 P D2 N2 S’
Avarohanam (Descending) : S’ N2 D2 P M1 G3 R2 S
It is a Janya raga, derived from Harikambhoji (see below), 28th of the Melakarta scale.
It’s origin is the Hindustani Kamaj Thaat. It is a late night raga and evokes the sringara rasa (love, beauty, attraction). A well loved raga, there are quite a few compositions which would be well known to the average listen like Brochevarevarura by Mysore Vasudevachar, Sitapati Na Manasuna and Sujana Jivana by Tyagaraja, Idadu padam Tookki by Papasanasam Sivan, the Varnam Mate Malayadwaja by Mutthiah Bhagavathar, and Sarasa Dala Nayana by Muthuswami Dikshithar. .
Note : The 12 notes in the octave are named as below. Please note that C is used as Sa for the sake of simplicity as the scale is relative in Carnatic Music. Also note that the scales paint only a superficial picture of the raga as the gamakas(ornamentations) are a very important part of a raga.
