Each week, Coventry and Canterbury choirs gloriously lead worshipers in liturgical music that embraces a wide range of traditions and styles, from ancient plainsong to gospel music. Coventry Choir sings about 60 percent of services, September through June, rehearsing every Thursday from 7:30 to 9:45 p.m. Canterbury Choir sings about 40 percent of services, September through June, rehearsing every Wednesday from 7:30 to 9 p.m. Both choirs have occasional Saturday morning rehearsals. Membership is by audition. Parishoners whose schedules don't allow the significant time commitment needed for Canterbury and Coventry choirs are invited to consider Summer Choir, which sings for the 11:15 a.m. service each Sunday, July through Labor Day weekend.
