In the early 1800s, Jonah Barrington, an Irish judge, bemoaned that the air chosen as the march for the Irish Volunteer Movement had “no merit whatever, being neither grand, nor martial, nor animating,” contrasting it with the zeal of French revolutionary music. The emotional impact of music might be a matter of taste, but such a statement is suggestive of an aesthetics, where political music, or music used for political purposes, should have specific qualities that could be identified and judged by listeners. This article explores how people in late eighteenth- and early nineteenth-century Ireland identified music as political, using theories of the effects and affects of sound during the period and a corpus of Irish political music as an access point into historical experiences of musical enjoyment. While the impacts of music on the body are challenging for historians to retrieve, scholarship from the history of emotions highlights the important role of normative frameworks of emotion in accessing embodied experience. Working from this perspective, this article argues that we can begin to access the sound of politics for audiences of this period, contributing to our understanding of the role of music in political life.
