Now a prominent instrument in the professional troupes, the khushtar viol was developed in the 1960s. It modeled its shape on instruments depicted in Xinjiang's early Buddhist cave murals. It is tuned and bowed like the professional ghij?k, but its tone is lower and softer, since the whole instrument is made of wood. It is also found in soprano and tenor versions.
