"This book explores the relationship between music and the visual arts in the late nineteenth and twentieth centuries, focusing on the modernist period. Reassessing the work of such composers and artists as Richard Wagner, Pablo Picasso, Paul Klee, Josef Matthias Hauer, and John Cage, Simon Shaw-Miller argues that despite modernism's advocacy of media purity and separation, the boundaries between art and music were permeable at this time, as they have been throughout history."--BOOK JACKET.
