“I suggest that composers give up using their music to change people’s minds. (When I say “minds,” I really mean people’s beliefs, opinions, and convictions.) I do not, please notice, suggest that anyone stop trying to change minds altogether, only that they stop using music to do it. Argument, not art, is the best tool for proving opinions. Music is poorly suited for that. But music is very well suited, or least it can be, for helping people to change their habits, especially habits of thinking and perceiving.”
