Sunayi, a Tajik musical instrument. The Han people call it the Tajik recorder. It is popular in Tashkurgan Tajik Autonomous County and Shache, Zepu, Yecheng, Pishan and other places in the southwest of Xinjiang Uygur Autonomous Region.

Sunaiyi's tube body is made of wood, mostly made of locally grown apple wood or apricot wood. The upper part is thicker and the lower part is thin. The tube body is 36 cm high, the outer diameter of the upper nozzle is 3 cm and the inner diameter is 2.2 cm, and the outer diameter of the lower nozzle is 1.5 cm and the inner diameter is 0.9 cm. The upper end of the pipe is blocked with a wooden top plug, the mouthpiece is made into a flat arc shape, and a groove is opened on one side of the wooden plug to form an air inlet channel with the pipe wall. A rectangular sounding whistle is opened directly below the nozzle, the hole is 2.3 cm long and 1 cm wide, and the lower half of the whistle is trimmed into an oblique sheet. The tube body has seven or eight circular sound holes (all have a rear hole), the diameter of which is 0.7 cm, and the rear hole is located between the two front sound holes. According to the sound hole, the distance between the holes is 2.6 cm, and the maximum distance between the holes is 23 cm from the lower mouth of the pipe.

The traditional folk production method is to use wood to cut into two halves, and then glue them together. In order to prevent the pipe body from cracking or leaking air, the joints are mostly affixed with thin wood chips. After polishing and smooth, the pipe body is wrapped up and down with three circles of thin leather strips.
