According to its form or physical appearance, there are two kinds of
kacapi: The
kacapi parahu (literally "boat
kacapi), also called
kacapi gelung, is a resonance box with an uncovered underside to allow the sound out. The sides of this kind of kacapi are tapered inward from top to bottom, which gives the instrument a boat-like shape. In ancient times, it was made directly from solid wood by perforating it. The
kacapi siter (literally "zither
kacapi) is a plan-parallel resonance box. Similar to the
kacapi parahu, its hole is located at the bottom. The upper and bottom sides of it form a trapezoid shape. For both kinds of
kacapi, each string is affixed to a small screw or peg on the top right-hand side of the box. They can be tuned in different systems:
pelog,
sorog/
madenda, or
slendro. Kacapi siter often tuned in Western diatonic scale for some purposes, such as
contemporary music. Nowadays, the resonance box of kacapi is made by gluing six wood-plates side by side. The
kacapi is traditionally played by sitting cross-legged on the floor. Thus, the strings are about 25 cm above the floor. Nowadays the
kacapi is sometimes placed on a wooden frame, so that the player can sit on a chair. If the
kacapi indung is played while sitting on the floor, usually a pillow or some other small object is placed under its left-hand side, as seen from the player, so that the sound can freely escape through the resonance hole in the bottom of the soundbox. Some kecapi are fitted with small feet, so that it is not necessary to lift them in this way. ==Functions==
