Stravinsky said that composition is selective improvisation, meaning that the same kernel of an idea that you have up on the stand as a jazz musician is the same one you write down as a composer.

Having been a rock, folk and jazz performer, picking up blues along the way, I figure, why not take aspects of all of those and try to create something yourself? I feel that it can all flow together. That's the way I feel about 12-tone, atonal music and tonal music. Why paint yourself into a corner?
