Funk is a music genre that originated in African-American communities in the mid-1960s when musicians created a rhythmic, danceable new form of music through a mixture of various music genres that were popular among African-Americans in the mid-20th century.

Funk typically consists of a complex percussive groove with rhythm instruments playing interlocking grooves that create a "hypnotic" and "danceable" feel. It uses the same richly colored extended chords found in bebop jazz, such as minor chords with added sevenths and elevenths, and dominant seventh chords with altered ninths and thirteenths.
