While he did not employ the twelve-tone technique, after three years teaching analysis of twelve-tone scores, including works by Arnold Schoenberg, he experimented with ways of making scales of other elements (including duration, articulation and dynamics) analogous to the chromatic pitch scale.
Han anvendte ikke selv tolvtoneteknikken, men efter at have undervist i analysen af tolvtonemusik i tre år, herunder i værker af Arnold Schoenberg, eksperimenterede han med måder at lave skalaer med andre elementer (herunder varighed, artikulation og dynamik) analogt til den chromatic pitch scale.
