At the Traditional Latin Mass, "the schola" sings Gregorian chant or plainsong. While "the choir", sings any type of music in any church (e.g. polyphony or A cappella aka singing in unison). The appropriate place for a schola (vs. a choir) is between the choir stalls known as the "chancel" aka choir or presbyterium. The chancel is often located beween the sanctuary link to sanctuary... and the nave but can be also placed on the side or even behind the main altar (e.g. at the Cathedral of the Blessed Sacrament in Sacramento). Most American parishes do not have a proper chancel, however in England it is quite common to find them.
Our sanctuary at St. Mary's Vacaville is a unique design (and sadly without a choir loft) does not allow for an approximation of a sanctuary-chancel distinction. Therefore, the choir's current location next to the organ is a strategic location given such design.
***We are currently working on getting a Gregorian Chant Class aka Chant Camp organized at St. Mary's (more details to come). Stay tuned for updates.
