The poetry of music, Copland intimates, is composed both by the musician, in the creation of music and its interpretation in performance, and by the listener, in the act of listening that is itself the work of reflective interpretation. This makes listening as much a creative act as composition and performance — not a passive receptivity to the object that is music, but an active practice that confers upon the object its meaning: an art to be mastered, a talent to be honed.
For Alfred North Whitehead, a car accident and the exposure of a pyramid to the sun on any given day are equivalent events:
We are accustomed to associate an event with a certain melodramatic quality. If a man is run over that is an event comprised within certain spatio-temporal limits. We are not accustomed to consider the endurance of the Great Pyramid throughout any definite day as an event. But the natural fact which is the Great Pyramid throughout a day, meaning thereby all nature within it, is an event of the same character as the man's accident, meaning thereby all nature with spatio-temporal limitations so as to include the man and the motor during the period when they were in contact.
Apparently architecture does the same job as set design, "it creates units of environment, atmosphere, or events"—whatever you wish to call them—but with more weight, carrying more material, slower. This is why it can raise the curtain more times and repeat "there it is again" for longer. Perhaps for this and other reasons there are periods in the history of architecture in which stage design or the folly, for example, have been an effective field of experimentation for serious architects.
When a client arrives at my studio, my job consists of preparing a "stage" for the length of time he desires, whether it be for a day or years, it is irrelevant in the end. A stage in which he can move under the sun "as if he were at home," though he walks stuttering at first before learning what will come in the script, be it kind or not, and which he will repeat a thousand times until he tires. When he tires, a panel is disassembled to readapt the children's room, the roof is demolished to make a study, the façades are decorated and life continues unperturbed.
