"There are two basic principles of musical structure I rely on. The first is expressed by the force of attraction, (gravity, love, concentration, creation), and the second lies in the idea of repetition, (materialization, duration). My mindfulness of this constitutes the only score. I find I must wait before the beginning of each performance until I am surprised by the first sound I make and the fact that it is made. Then, I feel ready to proceed."
