. . . (The numbers
of measures must be capable of having a square root.) E.G., if there are
1600 measures . . . these will be divided into
40 × 40 measures, and each 40 measures will be phrased in
the same proportions that divide the 40 parts into large sections
(e.g., 6, 7, 10, 5, 3, 9). This is a structural idea not distant in concept
from Hindu tala (except that tala has no beginning or ending, and is based
on pulsation rather than phraseology), the work of Anton Webern and Erik
Satie and hot jazz.
John Cage
