Kanhi is a musical instrument of stringed family, bowing branch of the Cham ethnic group. The appearance of Kanhi is nearly the same to those of two-stringed fiddle Nhi of the Viet ethnic group but its resonator is made of the tortoise-shell. Therefore, it is also called "Nhi Mai Rua" (Tortoise-shell Nhi).

The Kanhi consists of bamboo rod, 84cm in length, one end is put through the resonator, and the other is fitted two pegs to tune the string. Two silk strings is tuned at the fourth interval. One silk-string pulling two strings towards the part of the neck of the instrument is called "cu dan" (gauge), which is used to tune pitches of the sound. When the gauge is taken down to shorten the vocal chords, the sound is high and vice versa when it is taken up to expand the vocal chords, the sound is bass.

The bow is made of bow-shaped bamboo. The bowing string is made of horse tail fibre, 65cm in length, put between the two strings of the instrument. When performing, the player pulls, pushes and rubs the bowing string into the two strings to create sounds. The keyboard is made of soft and light wood. The middle of the keyboard is linked a part called "bridge" of the instrument" to hang the string. Because its sound is warm, soft and a bit mysterious and sad, the Cham people often perform it in the funeral and ceremonial singing.
