The choir enhances the liturgical celebrations by leading the music ministry at Sunday Masses through hymns and songs that will ensure the “full, conscious, and active participation in the liturgical celebration” (Sacrosanctum Concilium, 14). The whole church community benefits from participating in the Eucharist through prayerful music. St. Greg's has an adult choir, and Contemporary Ensemble and Chamber Singers. Rehearsals are held weekly for adult choir.
