The angklung is a musical instrument from Indonesia made of a varying number of bamboo tubes attached to a bamboo frame. The tubes are carved to have a resonant pitch when struck and are tuned to octaves, similar to American handbells. The base of the frame is held in one hand, whilst the other hand shakes the instrument. This causes a repeating note to sound. Each of three or more performers in an angklung ensemble play just one note or more, but altogether complete melodies are produced.
The angklung is popular throughout Southeast Asia, but it originated in what is now West Java and Banten provinces in Indonesia, and has been played by the Sundanese for many centuries. Angklung and its music has become the cultural identity of Sundanese communities in West Java and Banten.
