A lot of people ask me where music is going today. I think it's going in short phrases. If you listen, anybody with an ear can hear that. Music is always changing. It changes because of the times and the technology that's available, the material that things are made of, like plastic cars instead of steel. So when you hear an accident today it sounds different, not all the metal colliding like it was in the forties and fifties. Musicians pick up sounds and incorporate that into their playing, so the music that they make will be different.
Miles DavisThe music has gotten thick. Guys give me tunes and they're full of chords. I can't play them...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 variation. There will be fewer chords but infinite possibilities as to what to do with them.
