Music is a significant object of reflection for contemporary philosophers, yet little has been written on the interplay of music and thought. Franois Noudelmann critically engages the musicality of Barthes, Sartre and Nietzsche, all of whom were amateur piano players, giving an insightful reading of their work in light of their music. The practice of playing the piano was crucial to these philosphers, but their writing on the topic was scant, implicit, or in discordance with their philosophical oeuvre. Noudelmann reveals how the manner in which they played, the composers they explicitly and secretly adored, and the music they chose to write about is telling of these philosophers writing styles and thinking patterns. Noudelmann invites us to imagine the physical and theoretical practice of music as a dimension underpinning and resonating with their philosophical work proper. He thus unearths new perspectives on the philosophical trajectories of the three. Noudelmann has an elegant command of the texts under study, and understands the discursive points and concerns of philosophical and musical theorists of recent decades. He also brings to the work of Barthes, Sartre, and Nietzsche a sense of lived, embodied experience, raising the question of the relationship between philosophy and the senses, a philosophers life and thought.
