The ‘affective turn’ suggests that we pay attention to how affects create subjectivities, build communities, and shape new forms of politics in the making. It invites us to move beyond established humanities and social science paradigms and toward richer forms of contextual analysis by studying how bodies – human and otherwise – ‘act and are acted upon’ (Gregg and Seigworth 2010, 1). The ‘affective turn’ requires sensitive attention to a host of cognate terms and concepts – sentiment, emotion, reverberation, resonance, atmosphere, and far beyond, including the more specific trans-category of ‘affective politics’ as well as affective reinterpretations of the social. Music has long been recognized as a site where affective politics play out. However, existing scholarship often view Baruch Spinoza, Silvan Tomkins, Gilles Deleuze, and Brian Massumi as the founding fathers of affective thinking at the expense of related work in the broader tradition of music philosophy. We address this lacuna by discussing the relationship between music, affect, and politics in the work of Plato, Aristotle, Al-Farabi, Qian Sima, Johannes Tinctoris, René Descartes, Johann Gottfried von Herder, Jean-Jacques Rousseau, Theodor Adorno, Antoine Hennion, and Tia DeNora, as we aim to broaden, nuance, sharpen, and situate contemporary understandings of affective politics in music studies. In doing so, we discuss whether the affective turn is, perhaps, better understood as a ‘return’ to cross-disciplinary music research that situates the understandings of affective politics, relational agency, and political emotions within a longer history of music philosophy that, taken together, provide a more robust theoretical argument for the social and political force of musical sounds.
