Indian classical music is the classical music of the Indian subcontinent. It is generally described using terms like Marg Sangeet and Shastriya Sangeet. It has two major traditions: the North Indian classical music known as Hindustani and the South Indian expression known as Carnatic. These traditions were not distinct until about the 15th century. During the period of Mughal rule of the Indian subcontinent, the traditions separated and evolved into distinct forms. Hindustani music emphasizes improvisation and exploration of all aspects of a raga, while Carnatic performances tend to be short composition-based. However, the two systems continue to have more common features than differences. Another unique classical music tradition from Eastern part of India, i. e. Odissi music has evolved since two thousand years ago.

Carnatic music, known as Karnāṭaka saṃgīta or Karnāṭaka saṅgītam in the South Indian languages, is a system of music commonly associated with South India, including the modern Indian states of Andhra Pradesh, Karnataka, Kerala, Tamil Nadu and Telangana. It is one of two main subgenres of Indian classical music that evolved from ancient Hindu texts and traditions, particularly the Samaveda. The other subgenre is Hindustani music, which emerged as a distinct form because of Persian or Islamic influences from Northern India. The main emphasis in Carnatic music is on vocal music; most compositions are written to be sung, and even when played on instruments, they are meant to be performed in gāyaki (singing) style.
