Book excerpt: This edited volume explores the dialogue between art and music with that of mystical currents at the turn of the twentieth century. The volume draws on the most current research from both art historians and musicologists to present an interdisciplinary approach to the study of mysticism’s historical importance. The chapters in this edited volume gauge the scope of different interpretations of mysticism and illuminate how an exchange between the sister arts unveil an underlying stream of metaphysical, supernatural, and spiritual ideas over the course of the century. Case studies include Charles Tournemire, Joseph Péladan, Erik Satie, Hilma af Klint, Jean Sibelius, František Kupka, and Wassily Kandinsky. The contributors’ unique theoretical perspectives and disciplinary methodologies offer expert insight on both the rewards and inevitable aesthetic complications that arise when one artform meets another. The book will be of interest to scholars working in art history, musicology, visual culture, and mysticism.
