polytempic genesis, part xxxvi

The Polytempic Genesis Model

The polyrhythmic becomes the polymetric; the polytempic grows out of the polymetric. The polyrhythmic structure establishes the ratio relationships first — the proportional architecture of the streams, their mathematical kinship. Once a beat per minute is assigned to each individual line, over longer durations of the composition, the decisive act of individuation occurs: each line is cut loose from the shared grid and given its own pulse origin. From that point, the lines begin to take on their own life — their own melodies, their own tunings. The polymetric scaffold recedes into the background as generative history rather than ongoing governance. The lines remember their proportional origins but are no longer bound by them. The polyrhythmic is the seed; the polytempic is the mature organism.
