The three types of Sikh musicians - rababis, ragis, and dhadhis continued to flourish during the period of the Gurus. Guru Nanak started the rababi tradition by engaging Bhai Mardana as his accompanist-musician. Formerly the Muslim singers were called mirasis, but Guru Nanak gave them a new name - rababis, because they played on the rabab (rebec) and adopted the Sikh way of life in food, dress and manners. Some of the notable rababis after Mardana were his son Shahjada. Balwand and Satta, Babak - son of Satta, Chatra - the son of Babak, and Saddu and Baddu - the rababis used to perform kirtan regularly at Amritsar before the Partition in 1947. The last of the line of rababis was Bhai Chand whose kirtan the author had the privilege of listening to, before 1947. After the Partition of India, the rababis migrated to Pakistan, the line of rababis is almost dying out without Sikh patronage.
