The history of musical development in Iran (Persian music) dates back to the prehistoric era. The great legendary king, Jamshid, is credited with the invention of music. Music in Iran can be traced back to the days of the Elamite Empire (2500–644 BC). Fragmentary documents from various periods of the country's history establish that the ancient Persians possessed an elaborate musical culture. The Sassanid period (AD 226–651), in particular, has left us ample evidence pointing to the existence of a lively musical life in Persia. The names of some important musicians such as Barbod, Nakissa and Ramtin, and titles of some of their works have survived.
