In this completely rewritten and updated edition of his long-indispensable study, Malcolm MacDonald takes advantage of 30 years of recent scholarship, new biographical information, and deeper understanding of Schoenberg's aims and significance to produce a superb guide to Schoenberg's life and work. MacDonald demonstrates the indissoluble links among Schoenberg's musical language (particularly the enigmatic and influential twelve-tone method), his personal character, and his creative ideas, as well as the deep connection between his genius as a teacher and as a revolutionary composer.
