Our cathedral choir is composed of members of individual church choirs, so our only contribution during Holy Week is for the Chrism Mass. This year we had 23 singers plus a brass quintet and organ, with the following sung repertoire:

Prelude:

O Redemptor (chant)
Build Thee More Stately Mansions (G. Young)
O for a Heart to Praise My God (R. Smith)
Christ Became Obedient for Us unto Death (J. Lee)

Mass:

Entrance: O God Beyond all Praising (arr. R. Proulx)
Gloria: Community Mass (R. Proulx)
Psalm: Forever I Will Sing (W. Ferris)
Acclamation: Praise and Honor (P. French)
Preparation of Gifts: I Am Alpha and Omega (J. Stainer)
Ubi Caritas (Taize)
Holy/Memorial/Amen: Community Mass (R. Proulx)
Agnus Dei: (Jubilate Deo)
Communion: O Living Bread from Heaven
Let All Mortal Flesh Keep Silence
Hail True Body (anonymous)
Closing: Christ Is Made the Sure Foundation (tune: Angels from the Realms of Glory)

If you have a men's section that has been waiting to cut loose (but can be reined in when the women join) I Am Alpha and Omega is your ticket!
