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.
What mode is funk?
Funk is an evolution/combination of jazz and rock, essentially. It's thus going to be based on the scales used in these two. Major, Mixolydian and Dorian are used, just as they are in rock. The pentatonic blues scale probably figures in there, as all rock is based on the blues.
