I can’t have background music. Either I’m listening, or I’m writing. Music totally absorbs me. I attended a concert of the Southwest Chamber Winds in an art gallery, and the effect on my mind and energy was profound. Pattern itself has energy, and has emotional and intellectual effects. Through pace, implied directions, unexpected transitions that somehow flow, mood changes, and pauses, music can create humor or suspense, can make you wonder with every note what will happen next, and it has to both surprise and satisfy by the end. If it was predictable, it would be dull, but if it had no pattern or resolution, it would be noise, not music.
The concert made me want to write with the complexity, fire, and subtlety of classical music.
