“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.

Yves Castanet 

Messe Brève

Yves Castagnet, choir organist of Notre Dame Cathedral in Paris, is a luminary in the realm of sacred music. Renowned for his exceptional talent and profound musicality, Castagnet’s “Messe Brève” serves as a testament to his ability to seamlessly fuse tradition with innovation. “Messe Brève,” which was both his first composition and his first liturgical work, reflects not only his technical prowess but also his deep spiritual connection, capturing the essence of the liturgy in a contemporary musical language.

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 February 2, 2024.  Rehearsals will be held on Tuesday, January 30 and Wednesday, January 31 from 6:30-9:00 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. 

New to this MASSterwork will be an additional optional rehearsal to review individual vocal parts, held on Monday, January 22 in the Choir Room at St. Bernard Church.  

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!
