Abstract: We are trying to study classical Indian music by computational analysis of mutual dependences of all sounds in the hearing range as well as voice range. To understand mutual dependence we develop a concept of timbre which is at once perceptual as well as material. We give derivation of 22 shrutis (microtones) of classical Indian music as invariances of mutuality of sounds. We have constructed an atlas of consonance among these invariances and shown consonances of known ragas and even report unknown ragas. We also show plausibility of relating consonance of instrumental timbre with these invariances.
