One kind of art related to the vocal organ is the playing of the bamboo Jew's harp. This instrument is made of bamboo; Jew's harps are also made of metal or bone. We whittle bamboo or bone and make two small holes through the two ends of the whittled bamboo and furnish them with strings. Besides being played to accompany traditional short- songs, the bamboo Jew's harp is used for playing short melo-dies with special dedications, such as imitating mare camel's calls or camel trotting. Traditionally, the bamboo Jew's harp is played by mostly women and young girls, whereas the jaw harp is specifically used as a tool-literally, as a means of transportation-for shamans and their ancestral spirits. The jaw harp is played at the beginning and end of the shamanis- tic ritual of the Darkhad, Tsaatan and Khotgoid ethnic groups in northern Mongolia.
