Angklung, Tradional Music Instrument From West Java ,Indonesia

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 (used and played by the Sundanese since the ancient times).

In the early 20th century, the angklung was adopted in Thailand, where it is called angkalung (อังกะลุง). The Thai angklung are typically tuned in the Thai tuning system of seven equidistant steps per octave, and each angklung has three bamboo tubes tuned in three separate octaves rather than two, as is typical in Indonesia.
Angklung had also been adopted by its Austronesian neighbours, in particular by Malaysia and the Philippines, where they are rather played as part of bamboo xylophone orchestras. Formally introduced into Malaysia sometime after the end of confrontation, it found immediate popularity.They are generally played using a pentatonic scale similar to the Indonesian slendro, although in the Philippines, sets also come in the diatric and minor scales used to perform various Spanish-influenced folk music.
At least one Sundanese angklung buncis ensemble exists in the United States. Angklung Buncis Sukahejo is an ensemble at The Evergreen State College, and includes eighteen double rattles (nine tuned pairs) and four dog-dog drums.
