Funk is a music genre that originated in the mid to late 1960s when African-American musicians created a rhythmic, danceable new form of music through a mixture of soul music, jazz, and R&B. Funk de-emphasizes melody and harmony and brings a strong rhythmic groove of electric bass and drums to the foreground. Funk songs are often based on an extended vamp on a single chord, distinguishing them from R&B and soul songs, which are built on chord progressions. Funk uses the same extended chords found in bebop jazz, such as minor chords with added sevenths and elevenths, or dominant seventh chords with altered ninths.
