When you are accompanying someone, you are listening to them the way you listen to a Bach Chorale, where four parts are going on at the same time, all of which are gorgeous melodies, all being played simultaneously. ↗
So I write melodies - thirty, forty, fifty - then I cast them off until I have just two or three. If only one is needed, I go see the director and ask him to decide. ↗
I know I can't do everything myself. So I know I specialize in my melodies and I do some of my demo work. I pass it on to my producers who are much better at the production level. ↗
