About BanjoThe banjo is a stringed instrument with a thin membrane stretched over a frame or cavity to form a resonator. The membrane is typically circular, and usually made of plastic, or occasionally animal skin. Early forms of the instrument were fashioned by African-Americans in the United States, adapted from African instruments of similar design. The banjo is frequently associated with folk and country music, and has also been used in some rock songs. Several rock bands, such as The Eagles, Led Zeppelin, and The Allman Brothers, have used the five-string banjo in some of their songs.
