Introduction

Schoenberg's opera Moses und Aron constitutes one of the composer's central achievements. It is a work of great dramatic impact, rich sonic complexity, and profound spiritual and philosophical inquiry. It is also the locus for Schoenberg's most extended exploration of twelve-tone composition. After the Introduction to this chapter places the work into an historical context, our primary focus will be on the ways that conflict is built into the twelve-tone row as it induces mutually exclusive partitions of itself and then generates derived partitions that develop and interact with those primary partitions. The partitioned row forms are used to portray individuation and conflict among the opera's protagonists. They also raise questions about cognition and perception that are at the core of Schoenberg's musical expressivity. Having developed an extensive, although by no means exhaustive study of the row's properties, the penultimate section of the chapter inquires more deeply about Schoenberg's portrayal of God, Moses, and the music of the covenant within the opera's first scene.
