Document 11: Funk: Funk is a music genre that originated in African - American communities in the mid-1960s when African - American musicians created a rhythmic, danceable new form of music through a mixture of soul music, jazz, and rhythm and blues (R&B).

Like much of African - inspired music, funk typically consists of a complex groove with rhythm instruments playing interlocking grooves. Funk uses the same richly colored extended chords found in bebop jazz, such as minor chords with added sevenths and elevenths, or dominant seventh chords with altered ninths.
