Angklung is known as Angklung in Indonesian, and it is a bamboo instrument that is very popular among Indonesians. It is regarded not only by Indonesians as a symbol of national unity, but also as a cultural symbol of Java, known as the national musical instrument of Indonesia. In addition to the Gamelan instrument, the most distinctive instrumental music is Anglon.
In 2010, Anglon was listed as a world intangible cultural heritage, making this national treasure instrument more specially cared for and loved, Anglon is a must-play instrument for Javanese musicians overseas, and it is also the finale program for foreign guests, becoming a long-standing cultural treasure to show Indonesia to the world.
The main frame of Anglon is made of bamboo, in which two to four bamboo tubes are suspended with rattan threads. The bamboo tubes are carefully cut and sharpened by master craftsmen in order to produce a specific tone when the bamboo frame is shaken. Each Anglon produces only one note or chord, so several people need to work together in order to be able to play the tune. Traditionally, Anglon uses a pentatonic scale, but in 1938 the musician Daeng Soetigna introduced a diatonic scale to Anglon, giving rise to the famous angklung padaeng.
