Liturgical Function

This page groups hymns by the specific role they play in a service. Wikipedia notes that the hymn "Te Deum" "is sung or recited in the Liturgy of the Hours and in thanksgiving to God for a special blessing (such as the election of a pope, the consecration of a bishop, the canonization of a saint)." Browsing by liturgical function lets a visitor find every hymn used for the same specific purpose in worship.
