"[Y]ou've got to write with certain men in mind. You write just for their abilities and natural tendencies and give them places where they do their best—certain entrances and background stuff. You got to know each man to know what he'll react well to. One guy likes very simple ornamentation; another guy likes ornamentation better than the theme because it gives him a feeling of being a second mind. Every musician has his favorite licks and you gotta write to them."
