List of musical instruments by Hornbostel–Sachs number: 321.33

Tanged lutes are common in East Africa, as are a closely related class of instrument called spike lutes. These are instruments in which the handle does extends all the way through the resonator. A hereditary class of West African musicians, griots, play tanged lutes, and no other form of stringed instrument; non-griot performers in West Africa play a mixture of both spike lutes and tanged lutes. The resonator of East African lutes may be made of wood, metal (such as a discarded can) or a half-calabash gourd. Griot lutes are exclusively wood, while non-griot lutes occur in all three categories. Typically, calabash lutes have no more than two strings, while the wooden instruments generally have more. Non-griot lutes are not restricted by heredity, and are used for many social purposes, most commonly hunting. ==Classification==
