“MASSterworks” Series

In 2022, as we commemorated the 60th Anniversary of the Casavant Organ of St. Bernard Church, we began the tradition of offering a semiannual “MASSterwork”; a robust sacred music composition offered in its original intended setting, in the context of Holy Mass. We hope that you will join us for our upcoming event, either by singing in the choir, or by attending the First Friday Mass as we explore the rich treasures of our Roman Catholic faith.

Daniel Roth 

Missa Festiva Orbis Factor

Daniel Roth, known worldwide as one of the leading French organ virtuosos, has earned various prestigious positions as an interpreter and as a teacher. He began his career at the Sacré Cœur Basilica in Montmartre, Paris, and in 1985 became the titular organist at the St-Sulpice church as successor of Ch.M. Widor, M.Dupré, and JJGrunenwald. Roth’s “Missa Festiva Orbis Factor” contains the complete text of the Gregorian Mass XI that is sung alternately by the cantor, assembly, and choir, and is accompanied by two organs. 

Choristers are invited once again to participate in offering a glorious musical work in the context for which it was intended—the celebration of Holy Mass. We will sing for the First Friday Mass on September 6, 2024.  Rehearsals will be held on Tuesday, August 27 and September 3 from 7:00-9:00 P.M. at St. Bernard Church, 311 Washington Road. While we encourage you to attend both rehearsals because of the abbreviated schedule, we can accommodate individual schedules when necessary. All music for the Mass will be provided at no cost to you.  

It’s never too early to sign up to take advantage of this exciting choral opportunity.  Fill out the registration form below to secure your place in what promises to be an exciting and inspirational Mass. We hope to see you there!
