Angklung is a musical instrument made out of two bamboo tubes attached to a bamboo frame. The tubes are carved so that they have a resonant pitch when struck. The two tubes are tuned to octaves. The base of the frame is held with one hand while the other hand shakes the instrument rapidly from side to side. This causes a rapidly repeating note to sound. Thus each of three or more angklung performers in an ensemble will play just one note and together complete melodies are produced. Angklung is popular throughout Southeast Asia, but originated from Indonesia and it has been used and played by the Sundanese since the ancient times. The oldest angklung still exist is called Angklung Gubrag. The angklung was made in the 17th century in Jasinga, Bogor. Nowadays, some of those older angklung remain in Sri Bduga Museum Bandung. As time flown by, the angklung received a more international attention. In 1938, Daeng Soetigna, from Bandung, created angklung that is based on the diatonic scale instead of the traditional pélog or sléndro scales. Since then, angklung has been used for educational and entertainment purposes and are able to accompany western music instruments in an orchestra.
One of the first well-known performances of angklung in an orchestra was during the Bandung Conference in 1955. Udjo Ngalagena, a student of Daeng Soetigna, opened his “Saung Angklung” (House of Angklung) in 1966 as a centre for its development. UNESCO designated angklung as a Masterpiece of Oral and Intangible Heritage of Humanity on November 18, 2010. As part of the acknowledgment, UNESCO insisted that Indonesia preserve their heritage.
