Inspired by Arnold Schönberg’s 150th birthday, which is currently being celebrated worldwide, the new exhibition at the mdw’s Exilarte Center sheds light on the social and cultural milieu inhabited by the Second Viennese School’s founder. Particular attention is paid to both Alexander Zemlinsky—who taught Schönberg and introduced him to Vienna’s musical circles—and Schönberg’s pupil and eventual assistant Richard Hoffmann.
