Sound Sample
The cheng is a traditional Chinese instrument. It is also known as a curved board zither. It exists in various sizes.

The cheng produces a mystical sound also reminiscent of harp sounds. The individual sounds can be manipulated by pressing or vibrating the particular string.

During the Nara era (710–793) the cheng arrived in Japan where it is known as the koto. Playing the koto is one of the traditional arts of the imperial court and is cherished to this day.
