Muslim (Sufi) devotional song
A type of religious song, often a ghazal set to music, traditionally sung by Muslim musicians to the accompaniment of the sarangi or tanpura. In the West, Nusrat Fateh Ali Khan is one of the better-known qawwals, or singers of qawwali.
Qawwali (Urdu: قوٌالی, Hindi: क़वाली) is the devotional music of the Sufis of the Indian sub-continent. Qawwali is a vibrant musical tradition that stretches back more than 700 years. Originally performed mainly at Sufi shrines throughout what is now India and Pakistan, it has also gained mainstream popularity.
