You insist upon their being together?

QUESTION: What do you have to say about rhythm? Let us agree it is no longer a question of pattern, repetition, and variation.

ANSWER: There is no need for such agreement. Patterns, repetitions, and variations will arise and disappear. However, rhythm is durations of any length coexisting in any states of succession and synchronicity. The latter is liveliest, most unpredictably changing, when the parts are not fixed by a score but left independent of one another, no two performances yielding the same resultant durations. The former, succession, liveliest when (as in Morton Feldman's Intersections) it is not fixed but presented in situation-form, entrances being at any point within a given period of time.
