A traditional Indonesian zither commonly played in West Java (an area called Sunda) and in Bali. It often lends its haunting melody to religious ensembles and is usually paired with the suling, as well as voice. Sometimes spelled kacapi.

There are 2 kinds of kecapi:

• kecapi parahu (or gelung) - a resonance box with an uncovered underside to allow the sound out; the sides are tapered inward from top to bottom, giving the instrument a boat-like shape
• kecapi siter - also has a resonance box with its hole located underneath, but the overall shape is like a trapezium

The kecapi typically has 18-20 strings, arranged on a 5-tone scale. The strings are held with moveable bridges, like other transverse zithers such as the Japanese koto. The right fingernail plucks forward as the left middle finger pulls back. The body of the instrument is made of wood, and large kecapis are often ornamented with carvings. The strings are stretched across a metal bridge and 20 wooden pedestals, which are used for fine-tuning the instrument.
