Like soul, funk is based on dance music, so it has a strong "rhythmic role". The sound of funk is as much based on the "spaces between the notes" as the notes that are played; as such, rests between notes are important. While there are rhythmic similarities between funk and disco, funk has a "central dance beat that's slower, sexier and more syncopated than disco", and funk rhythm section musicians add more "subtextures", complexity and "personality" onto the main beat than a programmed synth-based disco ensemble.
