The chords used in funk songs typically imply a Dorian or Mixolydian mode, as opposed to the major or natural minor tonalities of most popular music. Melodic content was derived by mixing these modes with the blues scale. In the 1970s, jazz music drew upon funk to create a new subgenre of jazz-funk, which can be heard in recordings by Miles Davis (Live-Evil, On the Corner), and Herbie Hancock (Head Hunters).
