In an interview that year with critic Nat Hentoff, Miles explained the new approach. “When you go this way,” he said, “you can go on forever. You don’t have to worry about changes, and you can do more with time. It becomes a challenge to see how melodically inventive you are. … I think a movement in jazz is beginning, away from the conventional string of chords and a return to emphasis on melodic rather than harmonic variations. There will be fewer chords but infinite possibilities as to what to do with them.”
