This article uses a historical and socioeconomic approach to analyze the supply and demand of organists at the first Anglican cathedral built outside the British Isles: Holy Trinity, in Quebec City. The period of study spans from 1801 to 1967, the tenure of the first to the seventeenth cathedral organist. The purpose of this analysis is to form a theory of the adequacy or discrepancy between the proposals of cathedral leaders and the congregation (the requesters) and the requirements of the organists (the suppliers). In order to draw conclusions, the concepts of supply and demand are explained within the particular context of this study. The explanations of these two terms are based on the following concepts: field research carried out to find organists, recruitment strategies, the selection process, hiring incentives, employer expectations, content of final offers, the organists’ decisions regarding final offers, reasons for cessation of work, and pension claims. In addition to referring to principles of microeconomics regarding the theory of supply and demand, this study provides analytical elements specific to this context, such as the time required to search for an employee. The data underlying the analysis come from original research conducted in the archives of the Cathedral of the Holy Trinity, in Quebec City. The information collected and analyzed will broaden the scope of knowledge of the Anglican cathedrals in North America.
