This avenue of research studies the interactions between court and town, between Paris and beyond, in order to understand the evolutions of the various musical genres (e.g. opera, sacred and instrumental music). It looks at the core model and how it circulated, examining local responses to the model (acceptance, adoption or rejection). The dissemination of a repertoire was essentially linked to the movement of musicians, composers and performers. A professional move from one institution or place to another helped spread musical practices. Moreover, for a period marked by a fixed determinedly French musical style, the research also looks into the role of foreign influences, and the spread of French music outside national borders.
