Funk music is a kind of music that developed in African American communities in the mid-1960s when artists combined elements of soul, jazz, and rhythm and blues to produce a rhythmic, danceable new type of music that was both catchy and danceable (R&B). It downplays the importance of melody and chord progressions in favour of a powerful rhythmic groove created by a bassline played by an electric bassist and a drum part played by a percussionist, which is typically performed at slower tempos than other popular music. Throughout most situations, funk music comprised of a complex groove, with rhythm instruments playing interlocking grooves to produce a "hypnotic" and "danceable" feeling. Funk makes use of the same highly coloured extended chords that were used in bebop jazz, such as minor chords with additional sevenths and elevenths, or dominant seventh chords with altered ninths and thirteenths, among other arrangements.
