On 25 March 1526, on the Feast of the Annunciation, began the perpetual ceremony for Girard de Vienne, famous knight of the Order of the Golden Fleece. Not a single note survives, but many references can be found in a manuscript which gives us clues about the music of the liturgy for the soloists, the organ and the choir. In this experiment we reconstructed the Saint-Chapel of Dijon in 3D and re-enacted the music and the ceremony for the deceased knight.
