Program Notes The title is that of a painting by Bob Rauschenberg. Bob and I have been friends since 1952 and he and his work have been an influence on my work for many years and perhaps my work on his, in the early days. There has always been a layering and collage process in my work; the idea of 2 or more things transforming each other by being in “flexible” relationships to one another. Musical performance allows these relationships to change from performance to performance in a kind of endless re-association of the composed elements of that piece. In 1952 I called this a “mobile score” (having been influenced by Calder) but it has since been officially called “open form.” TRACER , being a kind of “homage” to Bob, has even more of this quality of endless and unexpected transformability than most of my other works, which is a condition that Bob himself might very well utilize if he were to compose sounds in time — which, as we know, he just might — at any moment. The four channels of tape material are on endless tape cassettes* (no functional beginning or end). The quality and time relationships of what is on each cassette does not change but the four cassettes will constantly be in different temporal and spatial relationships to one another from performance to performance. The conductor therefore cannot learn or predict the rhythms and placement of the four-channel sound environment that he will be “conversing” with in performance. The instrumental material is all music composed by me (as are the sounds on the tapes) scored in an “open-form” context — spontaneously combined, juxtaposed, modified, and “formed.” Working in the gap between art and life, as Bob Rauschenberg once said.

derived from the score will be one of many sporadic fragments. This wealth of fragments shows the numerous formal possibilities inherent in the work, and it is this realization, not the fragmentations, that must become the dominant characteristic of performance. Dynamics All indications of dynamics are relative to the instrumental technique and register of the particular sound called for, i.e., a string sound to be played col legno tratto, sul ponticello, with a dynamic of ffff, must be played as loudly as possible regardless of the dynamic intensity produced by the same dynamic marking in an instrument of a different nature. Thus, a low C in the Flute marked ffff is not expected to have the same volume as a middle-register tone marked ffff in a clarinet. This simply means that the flutist is to play his tones at the maximum volume available in that register of his instrument. The pppp indicates that the sound is to be as soft as possible. All dynamic indications are â€œbalancedâ€? in this way, relative to their acoustic functions within the event-structures and the characteristics of the instruments employed in them.
