* Introit: the Lord is asked to provide the deceased with perpetual light and eternal rest, making mention that all mortals are directed towards him and the sacrifices that are offered in his honor in Jerusalem;

* Kyrie eleison: the text is of little length and its three verses are practically identical, all with the objective of asking Christ for mercy;

* Gradual: In this third part of the requiem, the faithful ask the Lord that the dead enjoy eternal rest and endless light, as in the Introit, but the importance of having acted with justice during the life, so that your memory never fades;

* Tract: God is asked to absolve the souls of those who turn to him, so that they do not have to bear the weight of their sins and that, instead of suffering revenge, they can be eternally happy protected by his grace;

* Sequence: there is talk of day of the go to, the one in which everything will be reduced to mere ashes, of which the Sibyl and King David will be witnesses;

* Offertory: Christ is asked to free the souls of the dead from the infernal flames and the infinite abyss, so that they do not get lost in darkness, but rather find the holy light that was promised to Abraham and his descendants. Praises and supplications are offered to him in exchange for giving the dead eternal life;

Requiem* Holy: this part serves to exalt greatness and holiness of the Lord, whose glory floods heaven and earth, and to bless those in whose name they appear;

* Agnus Dei: similar in simplicity to Kyrie eleison, its lines are practically the same as each other and ask the Lamb of God give eternal rest to the dead;

* Communion: to close the requiem, we pray once again that the eternal light illuminates the deceased, exalting the mercy of the Lord.
