Kamānche, 1875-1900. Caucasus or northern Iran. Skin-covered sounding-box; overall: 58.5 x 26.8 cm (23 1/16 x 10 9/16 in.). Kamnche is a Persian term first used in the 10th century to describe an instrument that is sounded with a bow. From there, bowed instruments spread to Byzantium, Central Asia, the Far East, and then to Europe. In Egypt, it is known as the rabb, a term known throughout the Islamic world from North Africa to Southeast Asia. The names of musical instruments often reveal origin, context, or musical function. In Europe, North Africa, and Asia where contact with Middle Eastern culture occurred, variations of Arabic and Persian terms for instruments are widespread. Usually, related names refer to similar instruments; however, this is not always true. Among these "floating terms" are the names zrna, rabb, kmanja, ny, and dombak.
