René Leibowitz: Schoenberg and His School: The Contemporary Stage of the Language of Music (1947/1949)

Check out this post over here.

In this now-historic study of Schoenberg’s music and its impact on 20th-century composition, composer/conductor René Leibowitz–a student of both Schoenberg and Webern–traces the history of musical thought from the Renaissance through the early part of the 20th century, thus setting the stage for Schoenberg’s revolutionary abandonment of tonality. He also assesses the works of Schoenberg’s two star pupils. Alban Berg and Anton Webern He shows how Schoenberg’s methods were assimilated–conservatively by Berg and radically by Webern–maintaining throughout that theory was handmaiden to compositional artistry and not the other way around.
