Example 12 from Stockhausen's article "… wie die Zeit vergeht …", illustrating with a version of the series from Gruppen fur drei Orchester that, "if you start from the intervals of a proportion series, then with every step forward the register of each duration is also already chosen" (Stockhausen 1963b, 117). There are "a number of basic durations, indicated in metronome marks and corresponding with the pitch proportions within the series, reaching far as the octave positions (basic duration units)" (Leeuw 2005, 174), or "a duration scale which changes its 'time register' … corresponds to a twelve-tone scale that extends over more than one octave" (Misch 1998, 157–58).
