Music is such a problem in the time it takes.
When I dealt with set theory, I could never make it be the music that I wanted.
I'm not a music lover in the sense that I look for something to have on. I've never had that attitude to music.
I'm not an architectural composer.
My operas usually come from musical ideas rather than ideas about subject matter.
My attitude to writing is like when you do wallpapering, you remember where all the little bits are that don't meet. And then your friends say: It's terrific!
