“…He [Jackie McLean] explained his essentially spontaneous approach to improvisation: ‘First you have to have complete command of the instrument and then you leave the rest to your emotions. You go where your emotions take you. When I play I listen closely to the rhythm section and play exactly how I feel and then, too, if you have a melody in the beginning or some sort of form, a statement that you can go back to in the end, you can play from that.’”
