Carnatic and Hindustani Vocal

Hindustani Classical (North Indian) and Carnatic Classical (South Indian) are the two branches of Indian Classical music.

Hindustani classical music is the classical music of northern regions of the Indian subcontinent. It may also be called North Indian classical music or, in Hindustani, shastriya sangeet (śāstriya saṅgīt). It is played with instruments like the violin, sitar, and sarod. Its origins were in the 12th century CE when it diverged from Carnatic music, the classical tradition in South India. This Hindustani classical music combines the Indian classical music tradition with Perso-Arab musical knowledge, resulting in a unique tradition of the Gharana system of music education.

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 Karnataka, Andhra Pradesh, Telangana, Kerala and Tamil Nadu, and Sri Lanka. It is one of two main subgenres of Indian classical music that evolved from ancient Hindu Texts and traditions, particularly the Samaveda. 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.
