This study investigates the shifting meanings invested in the ragtime song “A Hot Time in the Old Time, Tonight” at the turn of the twentieth century. Complicating the tune's place in the canon of military, political, and national anthems was its associations with “vice,” black culture, and white supremacy. By mapping the ritual and representational uses of the song, this investigation demonstrates how “A Hot Time” served paradoxical functions that simultaneously affirmed and unsettled American exceptionalism. In doing so, this article traces the processes of obfuscation whereby black musical traditions and white supremacy defined America's distinctive national identity.
