Angklung is a traditional Indonesian instrument that is made from bamboo, originating from West Java. Angklung are actually a group of various sized hand-held instruments made from bamboo. When the angklung is shaken is produces a chord of music. The size of the angklung determines the chord that it produces. Songs are played with one person standing up behind a group of hanging angklung or by a group of people holding one angklung and playing their chord at the appropriate time within the song - much like a group of people would play bells in the west.
