This chapter begins by discussing the impulses that motivated Schoenberg to begin composing in the twelve-tone style: his desire to circulate through all twelve pitches of the chromatic scale, and his need to make the remainder of a piece develop from its initial material or Grundgestalt. It briefly traces his path toward twelve-tone music, as well as relating that journey to Josef Matthias Hauer’s work. The main part of the chapter defines the principal feature that set Schoenberg apart as a twelve-tone composer: the ‘musical idea’, and illustrates the musical idea as an overarching framework in an analysis of the Prelude from the Suite, op. 25. It then explains how Schoenberg’s followers and successors moved away from the notion of ‘idea’ as framework toward other modes of organization.

Entering into Anton Webern’s twelve-tone music and its complex reception history is like entering into a combat with the Hydra: cleave off one head of the Webern myth, and two more grow in its place. Taking a step back from the embattled scenes of the past in search of a broader vantage point, this chapter argues that the crux in understanding late Webern lies in understanding that the competing, often contradictory images of the composer that have emerged pose no real contradictions after all. Instead, in the same way that the Hydra’s separate heads are essentially connected entities, these different images are best understood as mediated with one another on a deeper level, representing different aspects of one and the same aesthetic concern: musical lyricism.
