Borobudur shows the world's first record of a bar percussion instrument. It appears to be a gambang style "xylophone" with ten wide bars resting over a trough resonator. We have no way to tell, but the bars were most likely made of wood or metal. The instrument is shown being played with two sticks with large, presumably padded, balls on the ends (see Kunst, "Hindu Javanese Musical Instruments," fig. 21). Cymbals resembling Balinese ceng ceng kopyak used in modern processional music can be seen as well as two-headed hand drums which appear to be of both Javanese barrel shape and Balinese conical styles.
