About BanjoThe banjo is a four-, five- or six-stringed instrument with a thin membrane stretched over a frame or cavity as a resonator, called the head. The membrane, or head, is typically made of plastic, although animal skin is still occasionally but rarely used, and the frame is typically circular. Early forms of the instrument were fashioned by Africans in America, adapted from African instruments of similar design. The banjo is frequently associated with folk, Irish traditional, and country music. Historically, the banjo occupied a central place in African American traditional music, before becoming popular in the minstrel shows of the 19th century.
