Indian classical music (Shastriya Sangeet / Mārga Sangeet) is the art-music tradition of the Indian subcontinent, organized around melodic frameworks called raga and cyclical meters called tala.
It has two major streams: Hindustani music in the North, which foregrounds extended improvisation and raga exploration, and Carnatic music in the South, which is composition-centric with structured but highly sophisticated improvisation.
A related eastern tradition is Odissi (from present-day Odisha), whose classical lineage spans roughly two millennia. Despite regional distinctions, these systems share common theoretical roots, performance aesthetics, and a spiritual-philosophical view of music as a vehicle for rasa (embodied aesthetic emotion).
