What is a raaga ?

Raaga can be defined as the swaras presented in the form of melody.

Raaga lakshana (structure) is determined by the Arohanam (ascending sequence of saptaswaras) and Avarohanam (descending sequence of saptaswaras). this sets the scale of the Raaga.

Basically Raagas can be grouped into two classes
1. Melakartha Raagas
2. Janya Raagas
