Khung, also known as Rusem, is a wind instrument in the northeastern part of India, especially in Manipur.
Similar to Pungi (snake charmer's pipe), the instrument has a small gourd (air container) into which air is filled through a small tube. There are six sound pipes, with three as a set, inserted inside the gourd. These pipes have small holes and free reeds at one end, which vibrates on blowing. The other ends of the pipes that are outside the gourd are covered with small fruit shells or bamboo cups to mute the sound. Khung produces sweet tunes on playing.
