Sacred music


The PDF files below are reproductions of the Gregorian Chant propers of the Mass in notation inspired by the Liber Usualis. These were developed for scholas and choirs of the apostolates of the Institute of Christ the King. They are free to download for use in the study and performance of sacred music.

The files are roughly organized by calendar day, which simplifies locating propers for upcoming celebrations. But please note: The indicated dates are only for organizing the files; it is absolutely necessary to consult a liturgical calendar or Ordo to determine which Mass is to be celebrated on a given day.

In a few cases, the files contain chants that might not be used on the indicated day, but are interesting for historical reasons. Unfortunately, it is not feasible to include explanatory notes in the files themselves. Chanters may find it helpful to consult the various editions of the Liber Usualis and Graduale Romanum, or ideally a Priest to indentify with certainty which chants are to be sung.

“Gregorian Chant has always been regarded as the supreme model for sacred music, so that it is fully legitimate to lay down the following rule: the more closely a composition for church approaches in its movement, inspiration and savor the Gregorian form, the more sacred and liturgical it becomes; and the more out of harmony it is with that supreme model, the less worthy it is of the temple. The ancient traditional Gregorian Chant must, therefore, in a large measure be restored to the functions of public worship, and the fact must be accepted by all that an ecclesiastical function loses none of its solemnity when accompanied by this music alone.”

Pope Pius X, Tra le Sollecitudini, 1903

“Finally, while respecting various styles and different and highly praiseworthy traditions, I desire, in accordance with the request advanced by the Synod Fathers, that Gregorian chant be suitably esteemed and employed as the chant proper to the Roman liturgy.”

Pope Benedict XVI, Sacramentum Caritatis, 2007
