Is all Indian music in a minor scale?
Concepts such as major or minor are totally irrelevant to Indian music. Every mode is an entity in its own right . True, both North and South Indian systems have a concept of a “natural scale” which is referred to as “shuddha swar saptak”. However in practice, this is simply a means to provide a base for notation and for purposed of instruction. It does not imply in special importance in performance situations.
