Angklung is a handmade musical instrument made from pair of bamboo, mounted in a bamboo frame, that produces sounds when shaken. Angklung originated from West Java in Sundanese community, although angklung played in Bali as well as a part of Gamelan orchestra. In 2010 UNESCO recognized angklung as an Intangible Heritage of Humanity.
Angklung is made from bamboo tube, cut in certain measurement to produce specific pitch. Each individual angklung has two or three bamboo tubes with different height which are mounted in a bamboo frame. Part of each bamboo is removed to create a slit opening on top. The bottom of the bamboo tube sits loosely in hole of bamboo frame, which permits the tube to move back and forth sideway. When shaken, this action makes bamboo tubes knock the bottom frame, thus creating a sound. Angklung is usually played by many people, each people responsible for one angklung to produce one note. Some expert players might be responsible for multiple angklungs. Each player shakes their angklung alternately, according to note in the music sheet to create a melody.
Originally angklung only has five pitches of pentatonic musical scale. The transition of Angklung from pentatonic to diatonic scale initiated in 1938 by Daeng Sutigna from Kuningan, West Java. This transition permitted angklung to play a wider arrange of music, including modern western music, therefore made it more popular. Nowadays Angklung orchestra flourish across Indonesia, from high school angklung club, to independent angklung orchestra.
