“…For instance, the normal form (0, 0.9, 6, 7, 8, 9) is farther from the normal form (0, 0.9, 2, 3, 6, 7) than it is from the non-normal (0, 1, 6, 6.9, 8, 9). My strategy can be adapted to such cases by choosing a region of space containing a transpositional boundary.45 SeeStuckenschmidt (1965). This pattern can be considered a subset of a more complex five-voice structure has two voices sounding a fifth, two sounding a tritone, and an additional voice moving in contrary motion to sound chord roots.…”
