This article offers a sonic reading of Gilles Deleuze’s political philosophy. It argues that Deleuze adopts a sonic-musical vocabulary to account for the affective and corporeal dimensions of politics or the ways that bodies and nonconscious forces shape political and epistemological experience. Suggesting that sonic expressions operate on both the musical and the linguistic register and inflect bodies before being consciously recognized, the article thus explores how the sound flows involved in political assemblages also find entrance into philosophical concepts. To (...) make this argument, the article traces several sonic figures – most prominently refrain, rhythm, and resonance – throughout Deleuze’s _oeuvre_ and puts those into conversation with sound studies scholarship. With this, the article makes two wider contributions. First, it traces connections between Deleuze’s early philosophical works and his later more overtly political collaborations with Guattari by way of sound to establish a notion of the political as an aesthetic-ecological field composed with and beyond human activity. Second, the article outlines parameters of a sonic political philosophy centered on affective involvement, embodied listening, and experimental thinking, thus also articulating the relevance of sound studies scholarship for political theory and Deleuzian philosophy.
