Music and Musicians of the court of Shah Jahan – A. Hatim.
The artists of the Qawwali school were Rauza Qawwal and Kalu Qawwal, the latter being a disciple of Sher Muhammad.
There were only two court musicians representing the Persian school of music, Muhammad Baqi Mughal, a good composer whose accomplishments declined owing to his taking too much opium, and Mir Imad, also a musician-composer, a Sayyid of Herat whose father had migrated from Central Asia.
