II. How is the Liturgy Celebrated?

From The Catechism of the Catholic Church

1156
“The musical tradition of the universal Church is a treasure of
inestimable value, greater even than that of any other art. the main reason for
this pre-eminence is that, as a combination of sacred music and words, it forms
a necessary or integral part of solemn liturgy.”²⁰ The composition
and singing of inspired psalms, often accompanied by musical instruments, were already
closely linked to the liturgical celebrations of the Old Covenant. the Church
continues and develops this tradition: “Address . . . one another in
psalms and hymns and spiritual songs, singing and making melody to the Lord
with all your heart.” “He who sings prays twice.”²¹
