Indonesian Angklung
Angklung is an Indonesian musical instrument consisting of two to four 
bamboo tubes suspended in a bamboo frame, bound with rattan cords. The 
tubes are carefully whittled and cut by a master craftsperson to produce
 certain notes when the bamboo frame is shaken or tapped. Each Angklung 
produces a single note or chord, so several players must collaborate in 
order to play melodies.
Traditional Angklungs use the pentatonic scale, 
but in 1938 musician Daeng Soetigna introduced Angklungs using the 
diatonic scale; these are known as 
angklung padaeng. The 
Angklung is closely related to traditional customs, arts and cultural 
identity in Indonesia, played during ceremonies such as rice planting, 
harvest and circumcision.
Angklung
The special black bamboo for the Angklung is 
harvested during the two weeks a year when the cicadas sing, and is cut 
at least three segments above the ground, to ensure the root continues 
to propagate. Angklung education is transmitted orally from generation 
to generation, and increasingly in educational institutions.
Because of 
the collaborative nature of 
Angklung music, playing promotes cooperation
 and mutual respect among the players, along with discipline, 
responsibility, concentration, development of imagination and memory, as
 well as artistic and musical feelings.
