The Kepyak is a percussion instrument played by the dalang (puppeteer) of a wayang performance in Java, Indonesia. It is a struck idiophone consisting of several bronze or iron plates attached by strings (in Surakarta) or a single plate (in Yogyakarta), which the dalang plays with a small mallet held between the toes of his right foot. It is placed on the side of the keprak, a wooden box which can also be played directly. The kepyak can also be played with a mallet (cempala), either in the hand in dance performance, or in the foot in wayang. The kepyak used in dance performances is smaller than that used in wayang. The use of the kepyak is called kepyakan.
