The establishment of the Sainte-Chapelle royale consisted of a treasurer, canons, and college - the members of which may have overlapped with the choir and instrumentalists.
Consequently, as with the Chapelle royale the Sainte-Chapelle originally indicated not only the building, but more the costs and functions of clerical and musical establishment attached to it.
Although this is not the direct ancestor of the Saint-Chapelle established to serve the new building in the 1240s, Duke Hugues' Sainte-Chapelle also found itself between royal and papal authority.
The masters were not only responsible for music for services, but also for the care of the enfants de la chapelle, the boys choir.
Although this was officially part of Charpentier's job, from the 1460s the non-musical responsibilities in regard to the boys in practice delegated to the maître de grammaire (grammar teacher) and sous-maîtres of the chapelle.
