The angklung is a musical instrument made of two to four bamboo tubes attached to a bamboo frame. The tubes are carved to have a resonant pitch when struck and are tuned to octaves. The base of the frame is held in one hand, whilst the other hand strikes the instrument. This causes a repeating note to sound. Each of three or more performers in an angklung ensemble play just one note or more, but altogether complete melodies are produced. The angklung is popular throughout Southeast Asia, but it originated in what is now West Java and Banten provinces in Indonesia, and has been played by the Sundanese for many centuries. Angklung and its music has become the cultural identity of Sundanese communities in West Java and Banten. Playing angklung as an orchestra requires cooperation and coordination, and is believed promotes the values of teamwork, mutual respect and social harmony. On November 18, 2010, UNESCO officially recognized Indonesian angklung as a Masterpiece of Oral and Intangible Heritage of Humanity, and encourage Indonesian people and government to safeguard, transmit, promote performances and to encourage the craftsmanship of angklung making.
