Rewapu is a stringed musical instrument that is commonly played by the people of Uigur, Tajik and Uzbek ethnicities. It has had a long history of 600 years since its invention in the 14th century. Due to the frequent economic and cultural communications between Xinjiang and other ethnic groups home and abroad, Uigur people created a few new musical instruments. They were based on old folk musical instrument and the strong points of the foreign ones. Rewapu was one of the new instruments that were handed down to the present generations.

Rewapu is primarily made of wood. In addition to its very special appearance, the body is slim and long. The top is bending, and there is a semi-ball resonance box at the bottom.

There are different forms of rewapu, with 3 to 9 strings. Usually, people use the most outward string to play the music, and the rest are used as resonancing strings.

The sound of rewapu is loud and clear, and the timber is bright and unique. It is can be played in solo, ensemble or accompaniment. While performing, the person standing or sitting is required to stay straight and keep the shoulders in balance. The instrument is horizontally put in front of the player and the organ is placed in the crook of the arm. The pole is between the thumb and index finger of the left hand. The music played by Rewapu sounds highly graceful.

Rewapu has a variety of forms. Although people of Uigur, Tajik and Uzbek ethnic groups all live within the region of the Xinjiang Uigur autonomous region, their instruments are different in category, form and name. The people of Tajik ethnic group call this instrument "rebubo", which is made of apricot wood. There are many kinds of re wa pu in Uigur. Its styles are divided into the new, kashi, duolang, and shepherd styles. Kashi rewapu is named after the place where it is welcomed. The sound is soft and low, and the tone is smooth. The outlook of Uzbek rewapu is similar to that of kashi, but their volume and tone are quite different. For the former, it is loud and its tone is clear and deep.
