Kayhan Kalhor is an Iranian Kurdish kamancheh and setar player, and a vocal composer. He has received three Grammy Award for Best Traditional World Music Album nominations. Kalhor also has earned two nominations and won one Grammy Award for Best Global Music Album as a member of the Silk Road Ensemble.

The kamancheh is an Iranian bowed string instrument used in Persian, Azerbaijani, Armenian, Kurdish, Georgian, Turkmen, and Uzbek music with slight variations in the structure of the instrument. The kamancheh is related to the rebab which is the historical ancestor of the kamancheh and the bowed Byzantine lyra. The strings are played with a variable-tension bow.
