The reliefs of Borobudur and other central Javanese temples of the period, including Prambanan and Candi Sari, depict many other instruments including zithers, lutes, harps, vessel drums (gatam), and transverse flutes. Most are extinct in Indonesia today and may have never really existed on the islands, possibly carved from memory by mainland artisans. Only the bar instrument, cymbals, and drums remain. Notably absent from all reliefs of this period are gongs.
