Two pianos playing patterns in fast, note–by–note alternation with each other, or one piano with head–gap tape delay at 7 1/2 ips or equivalent short delay.
"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."
Two unrealized proposals for both large, monumental and small, personal sound sculptures that function as listening instruments consisting of very large and small, exponential cones, the resonances of which are activated only by existing environmental noise, injecting no new sound of their own into these environments; participants then create music by activating keys that change the nature of the resonances.
