The music of the Indian subcontinent is usually divided into two major traditions of classical music: Hindustani music of North India and Karnatak music of South India, although many regions of India also have their own musical traditions that are independent of these.
Both Hindustani and Karnatak music use the system of ragas sets of pitches and small motives for melody construction and tala for rhythm. Ragas form a set of rules and patterns around which a musician can create his or her unique performance. Likewise, tala is a system of rhythmic structures based on the combination of stressed and unstressed beats. Within these rhythmic structures, musicians (1996.100.1) can create their own rhythmic patterns building off the compositional styles of others.
