What is "bamshad"

Bamshad (in Persian: بامشاد) was one of the four most famous and skilled musicians (with Barbad, Nagisa (Nakisa), and Ramtin) who lived in the Persian Sassanid dynasty when Xusro Parviz was in power (591-628). His name comes from his practice of playing music at dawn every day: "bam" and "shad" translate as "dawn" and "happiness".

The Persian lexicons, for example Dehḵodā's Loḡat-nāma, describe him as a well-known musician equal to Barbad. He is also mentioned in a poem by the Persian poet Manūčehrī.
