St. Barnabas maintains a high quality of worship and music, and the choir plays a central role in offering dignified service to God. Week after week, the choir, supported by the fine Casavant organ, sings the praise of God from the gallery, which allows for a remarkable musical presence. Under the direction of highly respected organist and choirmaster Wesley R. Warren, the choir presents a diverse range of sacred music. Within the Anglo-Catholic tradition of plainsong (normally sung in English, but occasionally in Latin), the choir's repertoire continues to represent a wide cross-section of traditional music from Renaissance polyphony (mass and motet settings by Palestrina, Victoria, Byrd, Tallis, di Lasso, etc.) to contemporary compositions (Willan, Howells, Bissell, Daley, and Warren, among others).
