This brings up a question for me. I’m in the process of converting and one of my wife’s biggest issues with the Catholicism is the lack of music. How much singing and of what goes on at Mass?
The Mass does have its share of singing; however, unlike the services of the Protestant ecclesial communities, which only center on the Wrrd, we have both the Word and the Sacrifice.
In the United States, most parishes will have an entrance hymn (although the standard is to sing an entrance anitphon). Then, if the Mass is on a Sunday or a Holy Day of Obligation, you will generally sing the Kyrie (Lord have mercy, Christ have mercy…) and the Gloria (Glory to God in the highest).
During the Liturgy of the Word, most parishes will sing the Responsorial Psalm. The faithful (and choir) will sing the response while the cantor sings the verse.
Then, after the reading of the Epistle, we have what is called the Gospel Acclamation. With the exception of Lent, it is “Allelua”. Given the penitential nature of Lent, the Church provides a few alternatives.
After the General Intercessions, we enter the Liturgy of the Euchairst. During this time, while the collection is taken up and the gifts are brought to the Altar, an offertory hymn is sung.
Then, we sing what are called the “Eucharistic acclamations (in some books)”. These are the Sanctus (Holy, Holy), the Memorial Acclamation (When we eat this bread… sung after the consecration of the Pecious Blood) and the Great Amen (the moment when the celebrant lifts both the Body and the Blood of Christ and offers Them to the Father.
Some parishes will chant the Pater Noster (Our Father). After the sign of peace, we sing the Agnus Dei (Lamb of God). Once the priest has consumed the Body and Blood of Christ, the Communion hymn will begin. It is either a hymn or an antiphon. The Communon hymn goes on, at least in my parish, until the last person has received. The Holy Father has recommended maintaining sacred silence after the reception of Holy Communion.
Once the final blessing has been imparted and the dismissal given, the recessional hymn begins.
So, as you can see, there is a lot of singing, but, most of the singing involves the parts of the Mass. I hope this helps.
