In the wake of Alexandre Maral’s research into the Royal Chapel at Versailles, and drawing on seminars and performance practice instigated by the CMBV, this project will investigate how music was addressed at an everyday level in the country’s most prestigious religious institution with its very particular form of liturgy. As such, in conjunction with the research centre at the Palace of Versailles, the CMBV is planning to release an annotated digital publication (TEI) of the Cérémonial historique manuscript (1 300 pages long) which was written in around 1730 by chapel cantor Jérôme Chupperelle for the chapel master. It offers a daily account of how the music was made to fit into the court’s complex, multi-faceted liturgical system.
