Recently the men’s schola of St. Patrick Church in Placerville made its debut at the Vigil of the Assumption (in the San Francisco Archdiocese).
It was a newly scheduled Mass, as they usually don’t have vigils for holy days of obligation.
Lesson #1: If you want to bring Gregorian chant to your parish, don’t take away anybody else’s beloved music (or time slot).
People have a lot of misguided assumptions around Gregorian chant. People who know that I (Diane Silva) was the founding chairman of the Ave Maria University sacred music department and that I once led a semi-professional choir Voci del Tesoro often assume only expert musicians can “pull off” Gregorian chant.
