Music is played and heard in time, yet it is also embodied in space by musical scores. The observation of a musical score turns time into space and allows musicians to embrace the flow of time in a single glance. This experience constitutes a symbol for the Eternal Present, the simultaneous knowledge of all time outside time. This book analyzes the implications of this view through a variety of interdisciplinary perspectives, linking theology, philosophy, literature, and music. It also studies how this theme has been foreshadowed in the writings of Dante and J. R. R. Tolkien, demonstrating the connections between their masterpieces and the aesthetics of their times. The result is a fascinating itinerary through the history of culture, thought, and music, but also a deeply theological and spiritual experience.
