The Bryn Athyn Cathedral Choir is the regular adult choir for the community. They primarily sing at the Cathedral Adult Service (11 am) approximately every alternate Sunday during the academic year, and serve as the core of the Festival Chorus at major church holidays. The choir is made up of adults from all walks of life from current students to retirees, and numbers about 35 singers. Rehearsals are on Thursday evenings between Labor Day and Memorial Day, and recently have been ending the academic year by singing a Bach Cantata at the first Sunset Organ Vespers of the summer in mid-May. Anyone interested in singing with the choir is welcome to contact the Director of Music.
