The Geopolitics of Voice argues that ideas about sound, listening, and voice were central to Indigenous and settler articulations of law and political form in the nineteenth century. Offering a new approach to the history of the senses in North American modernity, the book first reveals how colonial ideologies of orality and literacy—and more broadly, of sound and vision—were marshaled to represent Indigenous places and peoples as noisy, lawless, and non-sovereign. At its core, however, the book offers an account of how Indigenous intellectuals articulated their own critical understandings of the ways in which sonic and listening practices mediate a community’s normative and political orders. With chapters exploring the writing and performance of figures like Sequoyah (George Guess), Bamewawagezhikaquay (Jane Johnston Schoolcraft), Etahdleuh Doanmoe, Zitkala-Ša, Luther Standing Bear, and other lesser-known figures, the book builds a counterarchive of nineteenth century Indigenous sound and listening that is inseparable from the unfolding of dynamic articulations of sovereignty and normative authority. Building from what has been identified as the political turn in recent musicological scholarship on Indigeneity/colonialism, the book argues ultimately that Indigenous sonic thought not only exceeds the strictures of settler law but redefines “law” itself, not as the ossified written rules governing behavior, but as a society’s cherished norms, structures, and practices.
