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.
