Origins

In the ancient traditions of Hinduism, two musical genre appeared, namely Gandharva (formal, composed, ceremonial music) and Gana (informal, improvised, entertainment music). The Gandharva music also implied celestial, divine associations, while the Gana also implied singing. The Vedic Sanskrit musical tradition had spread widely in the Indian subcontinent, and according to Rowell, the ancient Tamil classics make it "abundantly clear that a cultivated musical tradition existed in South India as early as the last few pre-Christian centuries".

The classic Sanskrit text Natya Shastra is at the foundation of the numerous classical music and dance traditions of India. Before Natyashastra was finalized, the ancient Indian traditions had classified musical instruments into four groups based on their acoustic principle (how they work, rather than the material they are made of) for example flute which works with gracious in and out flow of air. These four categories are accepted as given and are four separate chapters in the Natyashastra, one each on stringed instruments (chordophones), hollow instruments (aerophones), solid instruments (idiophones), and covered instruments (membranophones).

Of these, states Levis Rowell, the idiophone in the form of "small bronze cymbals" were used for tala. Almost the entire chapter of Natyashastra on idiophones, by Bharata, is a theoretical treatise on the system of tala. Time keeping with idiophones was considered a separate function than that of percussion (membranophones), in the early Indian thought on music theory.

The early 13th century Sanskrit text Sangitaratnakara (literally, "Ocean of Music and Dance"), by Sarngadeva patronized by King Sighana of the Yadava dynasty in Maharashtra, mentions and discusses ragas and talas. He identifies seven tala families, then subdivides them into rhythmic ratios, presenting a methodology for improvization and composition that continues to inspire modern era Indian musicians. Sangitaratnakara is one of the most complete historic medieval era Hindu treatises on this subject that has survived into the modern era, that relates to the structure, technique and reasoning behind ragas and talas.

The centrality and significance of music in ancient and early medieval India is also expressed in numerous temple and shrine reliefs, in Buddhism, Hinduism and Jainism, such as through the carving of musicians with cymbals at the fifth century Pavaya temple sculpture near Gwalior, and the Ellora Caves.
