In the winter of 1772–1773, Joseph Johnson (Mohegan/Brothertown) copied musical notation into eight books for Christian Native Americans in Farmington, Connecticut, a town established by English settler colonists on the land known as Tunxis Sepus. Johnson did so because, as he wrote in his diary, “The indians are all desireous of haveing Gamuts.” Johnson's “gamuts” have not survived, but their erstwhile existence reveals hymnody's important role within the Native community in Farmington as well as cross-culturally with the English settler colonists. In order to reconstruct the missing music books and assess their sociocultural significance, this article proposes a surrogate bibliography, gathering a constellation of sources among which Johnson's books would have circulated and gained meaning for Native American Christians and English colonists (including other printed and manuscript music, wampum, and legal documents pertaining to land transfer). By bringing together this multi-modal network of materials, this essay seeks to redress the material and epistemological effects of a colonialist archive. On one level, this is a case study that focuses on a short period of time in order to document the impact on sacred music of conversion, literacy, shifting intercultural relations, and a drive to preserve sovereignty. On another, this article presents a methodological intervention for dealing with lost materials and colonialist archives without recourse to discourses of recovery or discovery, the latter of which is considered through the framework of what I term “archival orientalism.”
