What are the components of the Ordinary in the context of sacred music?

In the context of sacred music, the Ordinary refers specifically to the parts of the mass that remain the same and are consistently used during the liturgy regardless of the specific celebration. The components identified in the correct response—Kyrie, Gloria, Credo, Sanctus, Benedictus, and Agnus Dei—are integral to the structure of the Catholic Mass. Each of these elements corresponds to significant moments in the service and serves both musical and liturgical functions.

The Kyrie is a plea for mercy; the Gloria is a song of praise; the Credo is the affirmation of faith; the Sanctus is a hymn of praise; the Benedictus is a blessing; and the Agnus Dei, which means "Lamb of God," is a litany prior to the breaking of the bread. Together, these components create a foundation for the mass and embody key theological themes, making them essential to the understanding of sacred music within this context. This structure and purpose underscore their prominence as part of the Ordinary.

Other options, while related to sacred music, either describe parts that are not fixed (like hymns and prayers) or pertain to different aspects of the liturgy not categorized solely as the Ordinary.
