Angklung is an ancient instrument played in southeast Asia, Malaysia and Indonesia. An instrument of the percussion family, the angklung is made of bamboo tubes loosely attached to a bar. The instrument is played by shaking it, which causes the bamboo tubes to strike each other, producing a tone. Angklungs can play only one note, but the larger the angklung, the deeper the pitch it produces. Angklung music is similar to hand bell music, in that you need one angklung per musician and at least two or three musicians playing together to create a harmony.
