The Mass, the Eucharist of Catholic worship (= Latin: Missa; Italian: Messa; French & German: Messe), has long provided texts for musical setting. The Ordinary of the Mass, the normally recurrent parts of the liturgy, consists of the Kyrie eleison (Lord have mercy), Gloria (Glory be to God in the highest), Credo (I believe), Sanctus (Holy, holy, holy), Benedictus (Blessed be he who comes in the name of the Lord) and the Agnus Dei (Lamb of God). These are the texts most often set. The Proper of the Mass changes from day to day, according to the season or the occasion. The texts of the Proper are less often set, except for texts that may be used with some frequency.
