be found in Nigeria and East Africa. Southeast Asia The instruments were used differently, depending on the cultures. In Cambodia, the Kong ring was plucked, used as a substitute for the sound of a circle of gongs, similar to the way a piano can substitute for an orchestra. In the Philippines, the zither strings were plucked but also hammered with a stick, like a drum. Off the coast of Burma and Thailand, the Moken people played their with a bow. Bamboo-tube-zithers the Kong ring in Cambodia, the Đàn goong in Vietnam. The instruments are also found in Burma and Thailand among the Pa'O (Black Karen), Kayaw (Red Karen), Sgaw Karen, Khamu and Shan peoples. The Khamu have more than one kind of bamboo-tube zither, with bamboo strings. The bring is a parallel string zither, used fur percussion. Like other parallel-string percussive bamboo zithers, it has two stings cut from the bamboo, the stings linked together with a thin piece of bamboo, a small hole cut into the tube wall below The connector. The bring is different than many tube zithers, having the two ends of the bamboo tube open. One end is held against the musician's body while playing it, closing that end, and the musician uses a hand to cover and uncover the other hole, changing the sound. They also have zithers designed for plucking. Indonesia, Java, Sumatra Early knowledge of Indonesian musical instruments comes from artwork and literature of the Hindu-Javanese civilization, which began with Hindu colonists in the fifth century AD. Because bamboo instruments decay, evidence of them comes through iconography, images in art, and literature. It is likely that the instruments pre-date their first representation in imagery. The instrument is found in the Kinddung Sunda, a work in Middle Javanese which was used in about the 14th and 15th centuries. In that work, it was called the guntang, and is still called that in Bali. The instrument is found in the Kinddung Sunda, a work in Middle Javanese which was used in about the 14th and 15th centuries. It is also present in the "entire archipelago" but under different names, including the gumbeng or bumbeng. Instruments may be created with single strings, pairs of strings (parallel strings), and with three or more strings (polychordal). The number of strings influences how they are played. Instruments with three or fewer strings are played like drums, the strings beaten
