Under the leadership of Music Director Murray Walker, Calvary's outstanding traditional Anglican choir leads the congregation in song every Sunday at the 10:00 a.m. service, September through June. Membership in the choir is open to any Calvary parishioner who wishes to join. Non-parishioners may join by audition. The choir rehearses on Wednesday evenings from 7:00 p.m. until 9:00 p.m. and on Sunday mornings at 9:00 a.m. (between the two regular Sunday services).

The musical tradition at Calvary is rich and varied. In addition to hymns and mass settings from the Episcopal Hymnal 1982, on any given Sunday one might also expect to hear plainchant, Anglican chant, and/or Taize chant. Choral anthems during the Offertory (and occasionally during Communion) are drawn from the entire breadth of classical ecclesiastial choral music, from the Rennaissance through the 21st Century.
