Friedrich Nietzsche (1844-1900) was not only a philosopher who loved and wrote about music; he was also a musician, pianist, and composer. In this ground-breaking volume, philosophers, historians, musicians, and musicologists come together to explore Nietzsche's thought and music in all its complexity. Starting from the role that music played in the formation and articulation of Nietzsche's thought, as well as the influence that contemporary composers had on him, the essays provide an in-depth analysis of the structural and stylistic aspects of his compositions. The volume highlights the significance of music in Nietzsche's life and looks deeply at his musical experiments which led to a new and radically different style of composition in relation with his philosophical thought. It also traces the influence that Nietzsche had on many other musicians and musical genres, from Russian composers to current rock music and heavy metal.
