Unlike bebop jazz, with its complex, rapid-fire chord changes, funk virtually abandoned chord changes, creating static single chord vamps (often alternating a minor seventh chord and a related dominant seventh chord, such as A minor to D7) with melodo-harmonic movement and a complex, driving rhythmic feel. Even though some funk songs are mainly one-chord vamps, the rhythm section musicians may embellish this chord by moving it up or down a semitone or a tone to create chromatic passing chords. For example, "Play that funky music" (by Wild Cherry) mainly uses an E ninth chord, but it also uses F#9 and F9.
