Moïse et Aaron is the French edition of Arnold Schoenberg's opera in two acts, exploring the biblical narrative of Moses and his brother Aaron. The work examines themes of faith, divine law, and the tension between spiritual ideals and human limitations through Schoenberg's distinctive twelve-tone compositional technique. This paperback edition presents the libretto and musical score, offering insight into one of the composer's most ambitious theatrical works, which remained unfinished at his death in 1951. The opera grapples with profound questions about monotheism, leadership, and the nature of artistic expression in the face of incomprehensible divine will.
