"Khushtar is part of the ancient Uyghur musical tradition. It was handmade in the tradition of Uyghur Master Instrument makers in Kashgar, Xinjiang - western border of China and Turkestan.
Khushtar is made from the wood of a mulberry tree. It has 11 strings; four are for playing, as with a normal violin, and the others are sympathetic strings that resonate along with the bowed strings (similar to a viola d'amore).
The Khushtar is named for the carved bird that is placed on top of the handle. Khush means bird, and tar means strings. The sound of a Khushtar is very clear and resonate, reminiscent of a birdsong. The Khushtar evolved, in ancient Kashgar, from the venerable Ghijek instrument."

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 ghijak, but its tone is lower and softer, since the whole instrument is made of wood. It is also found in soprano and tenor versions."
