Hindustani classical music is the Hindustani or North Indian style of Indian classical music found throughout the northern Indian subcontinent. The style is sometimes called North Indian classical music or Shāstriya Sangīt. It is a tradition that originated in Vedic ritual chants and has been evolving since the 12th century CE, primarily in what is now North India, Pakistan and Bangladesh and to some extent in Nepal and Afghanistan. Today, it is one of the two subgenres of Indian classical music, the other being Carnatic music, the classical tradition of South India.CharacteristicsThe tradition was born out of a cultural synthesis of several musical traditions: the Vedic chant tradition, dating back to more than three thousand years ago, the ancient Persian tradition of Musiqi-e assil, and various folk traditions prevalent in the region.It is traditional for performers who have reached a distinguished level of achievement to be awarded titles of respect; Hindus are usually referred to as pandit and Muslims as ustad. An aspect of Hindustani music going back to Sufi times is the tradition of religious neutrality: Muslim ustads may sing compositions in praise of Hindu deities, and vice versa.
