The chadagan (чадаган) is a Tuvan bridge zither.
It usually has 16 strings and is tuned to a pentatonic scale.
[1] The number of strings varies, and the bridge is sometimes movable.
Although it is usually plucked, it may also be played by striking with thin sticks, like a hammered dulcimer.
Related instruments are the Mongolian yatga, the Khakas chatkhan (or jadagan), the Japanese koto, and the Chinese guzheng.
