Philip Friedheim has described "" as Schoenberg's "only lengthy work in an athematic style", where no musical material returns once stated over the course of 426 measures. In his analysis of the structure, one indication of the complexity of the music is that the first scene of over 30 bars contains 9 meter changes and 16 tempo changes. Herbert Buchanan has countered this description of the work as "athematic", and the general impression of it as "atonal", in his own analysis.
