Love as Tonal Contract: A Phenomenological Account of Affective Sovereignty and Ethical Binding

This paper proposes a phenomenological reframing of love as a **tonal contract** rather than an emotional state or social construction. Drawing on Heideggerian attunement (*Stimmung*), Levinasian responsibility, and Merleau-Pontian embodiment, I argue that love constitutes an **ontological commitment** enacted through prosodic-affective modulation before it becomes conceptually articulated. Unlike traditional theories that treat love as either biological mechanism or cultural performance, this account positions love as a **revelatory event** through which subjects enter into irreversible ethical binding. Integrating insights from phenomenology, speech act theory, and prosody research, I develop a framework for understanding love as an **ontological transformation** in the structure of being-with-others. The paradox of love—that it simultaneously establishes sovereignty (autonomy in commitment) and vulnerability (exposure to the Other)—is explained through analysis of how prosodic commitment creates what I term "affective sovereignty": a domain of ethical responsibility that the subject freely assumes yet cannot unilaterally dissolve. Through detailed examination of performative utterances ("I love you"), the temporality of commitment, and contemporary questions about simulated affection, the paper demonstrates how this framework illuminates both intimate relationships and broader questions of ethical authenticity. I conclude by exploring implications for understanding trust, promising, and the foundations of intersubjective ethics.
