The most indigenous Southeast Asian (Malaysia, Indonesia, Singapore and Brunei)bamboo idiophone is the angklung, the bamboo shaker. Concussion idiophones are struck together, usually in pairs. The instruments is normally shaken rather than struck. They include vessel types, with loose ratting objects enclosed in a container; strung rattles, with small, hard objects tied together or to a handle; and frame rattles, such as the sistrum and the Javanese angklung (tuned bamboo tubes sliding within a framework). The jingle, or pellet, bell is a metal vessel rattle, not a true bell. Angklung is a popular bamboo musical instrument in Southeast Asia. It I s the easiest instrument to play: You just shake it.
An angklung is a pair (or more) of bamboo tubes mounted on a bamboo frame. The tubes are in different lengths and are cut halves at the upper two-birds. The lower end of each tube is closed by a node. Two prongs extend out and fit loosely into a corresponding slot of the horizontal bass tube.
The structure of an angklung
The two tubes are tuned an octave apart (three tubes can be two octaves or can form a chord). When shaken, the concussion of the tubes against the base procedures a pitch. Since each instrument makes only one pitch, it takes many single angklungs to make a complete melody.
Even though angklung can be found in many parts of Southeast Asia, it is generally believed that it originated on the island of Java. Traditional angklung music is also used in East Java, Central Java and other islands. However the Angklung is now widely played in many parts of Malaysia.
