Phoenix Gregorian Chant Group

The Phoenix Gregorian Chant Group provides an informal and relaxed opportunity to sing with others and explore the Gregorian repertory together. Our goal is to improve music reading skills rather than refining and perfecting chants for public performance. There is no audience, and everyone is expected to participate in the singing. Singers of all ages and all musical and religious backgrounds are welcome! We usually meet 3:30 to 5:00 on the second Sunday of each month in the parish hall of Mater Misericordiae Catholic Church at 1537 W. Monroe St. in downtown Phoenix. Enter through the east side gate and the double doors under the church sign (doors will be unlocked by 3:15). Extra copies of the Liber Brevior are available to borrow and can also be purchased for $30 (check or exact change is appreciated). If you're new, please familiarize yourself with the Fundamentals of Gregorian Chant.
