I'm a writer who plays the piano. As I write, I find new things I like. I make them into what I call principles, and they become part of my playing vocabulary. That's the secret of what you get from composing. You get to discover things that you wouldn't ordinarily do. Much like a speech pattern, your improvisation patterns can get stale if you don't keep building your vocabulary. Each time you re voice something, you change the sound. When you do this enough, you get used to those sounds, and they start to come out as you play. You end up using voicings that aren't common, which gives you an auditory identity.
