Music at St. Mary’s is a ministry for all ages who wish to worship through song. In addition to liturgical music at Sunday services and major feast days,  St. Mary’s invites the community to free concerts featuring area artists and traditional Compline and Evensong offerings.

As you consider opportunities for service and growth for yourself and/or your children for the upcoming months, please consider the joy, fellowship, and blessing of singing with one of St. Mary’s Choirs.

The St. Mary’s Music Ministry is composed of six choirs with more than 100 participants (Choir parents count too!). St. Mary’s Choirs are affiliated with the Royal School of Church Music.


In the Treble Choir, boys and girls from kindergarten through third grade make a joyful noise while learning about the singing voice, breath, and musical notation. The choir sings once a month at the 9:00 a.m. Holy Eucharist and practice weekly on Thursdays at 6:30 p.m.


Adults sing primarily at 11:15 a.m. each Sunday throughout the school year and at 10:00 a.m. during the summer. In addition to the Sunday morning Holy Eucharist, this choir sings for special liturgies, including Evensong, All Saints Requiem, and Lessons & Carols. This choir practices weekly on Thursdays at 7:30 p.m.


Adults and teenagers Directed by Bass Section Leader and Assisting Music Director Gregory Stuart, this choir rehearses on a project by project basis (such as for Advent Lessons & Carols), thus a regular rehearsal commitment is not required.


Older children and teens in the Boys and Girls Choir develop their skills as young musicians and leaders of the 9:00 a.m. liturgy and other services through the training program of the Royal School of Church Music and with yearly choir trips.  The Boys & Girls Choir sings at the 9:00 a.m. Holy Eucharist service several times a month throughout the school year. Experienced choristers have the opportunity to sing with the Choir of Men & Women on selected occasions. This choir practices weekly on Thursdays at 6:30 p.m.


If we consider and ask ourselves what sort of music we should wish to hear on entering a church we should surely, in describing our ideal, say first of all that it must be something different from what is heard elsewhere; that it should be a sacred music, devoted to its purpose, a music whose peace would

still passion, whose dignity should strengthen our faith, whose unquestioned beauty should find a home in our hearts, to cheer us in life and death; a music worthy of the fair temples in which we meet and of the holy words of our liturgy; a music whose expression of the mystery of things unseen never allowed any trifling motive to ruffle the sanctity of its reserve. What power for good such a music would have!”

In 1998 as part of the church renovation and expansion, the St. Mary’s organ was installed by Lively-Fulcher Pipe Organ Builders of Washington, D.C. This organ was crafted foremost to support hymn singing, accompany choral anthems, and play organ literature spanning many periods. The instrument currently has 25 speaking stops with preparations for two further voices to be added as funds permit. The key action is mechanical and the stop action is electric, complete with combination action and eight levels of memory. The tonal inspiration for the instrument is firmly based in England but with a dash of French color and exuberance that was so common in English-built organs of the 18th and 19th centuries. The support of the robust hymn singing coupled with the varied and ambitious choral program at Saint Mary’s is the driving force behind the tonal aesthetic of the instrument.
