In recent years, the history of sound has developed into a rich body of interdisciplinary scholarship. This article explores the benefits of considering sonic evidence alongside a host of other material; teaching and writing histories with—rather than of—sound. In the classroom, this kind of “history with sound” is particularly useful for its ability to cut across lines of scholarly inquiry. This makes sound an especially potent resource when teaching the history of the United States during the Gilded Age and Progressive Era. During these years, American society underwent a many-sided process of development difficult to adequately narrativize. The study of sound, with its ability to link numerous trends and dynamics within densely layered events, can help address this issue. Providing insight into the practices and problems of everyday life, such sonic history can reveal the interplay of change and continuity that defined the social experience of the turn-of-the-century United States. Focused on sound in New York, this article provides an overview of the topic’s historiography before examining a series of distinct case studies for classroom use.
