Corpus Christi Watershed

Pope Saint Paul VI (3 April 1969): “Although the text of the Roman Gradual—at least that which concerns the singing—has not been changed, the Entrance antiphons and Communions antiphons have been revised for Masses without singing.”

Improvising – and Praying – on the Propers

Richard J. Clark · January 10, 2014

N RECENT YEARS, I HAVE ADOPTED THE HABIT of improvising on the propers when appropriate and applicable. Most often, this may be at a mass without choir, or perhaps one of the “off-peak” masses. This also comes in the form of the occasional prelude improvisation, usually on the Introit. In doing so, one can never be reminded enough of these words from the Second Vatican Council:

“In the Latin Church the pipe organ is to be held in high esteem, for it is the traditional instrument which adds a wonderful splendor to the Church’s ceremonies and powerfully lifts up man’s mind to God and to higher things.” (Sacrosanctum Concilium, 120),

Coupled with the above phrase must be the following:

“Therefore sacred music is to be considered the more holy in proportion as it is more closely connected with the liturgical action…” (Sacrosanctum Concillium § 112)

When one can print the text in a worship aid, the prayerful connection is easily made. However, when this is not the case, what purpose does it serve, and why persist in doing it? The answer is more closely related to the interior prayer life of the organist. Not only is a melody the subject of improvisation, but also the text must be in the heart of the improviser throughout!

To make a habit of carrying these texts in one’s heart on a regular basis can only be helpful to the prayer life of the organist. But what does this accomplish for anyone else? What does this accomplish liturgically? Well, a few things. First of all, a must read is Part Four of Dr. William Mahrt’s “The Musical Shape of the Liturgy: The Function of the Organ.” Dr. Marhrt points out the ancient common practice:

“The prescription found in medieval liturgical books that a melody which is to be carried by the organ is cantabitur in organis (it shall be sung upon the organ), or even dicetur in organis (it shall be said on the organ), and it acknowledges this function of implicitly bearing the text.”

However, this applies to well-known sacred melodies that a listener would easily recognize. The most common example are masses sung in alternatum with the organ. It is clearly understood what the text is whether sung or played.

But what about melodies that are unfamiliar, especially in a present-day context? Consider too, that the heart of improvisation is elaboration. Then what? Does anyone have any idea what we are doing? Is it important? Very few Offertory melodies are being whistled on the way out the door.

In such cases, one would not argue that the organ is speaking the text in the sense of ”dicetur in organis” (it shall be said on the organ). Rather, the music must serve to the heart of prayer in of itself, as well as serve the ongoing liturgical action, which improvisation tends to do fairly well.

CLOSE FRIEND, A PRIEST once told me years ago something I’ve never forgotten. “The people don’t need to know what it is to understand it.” In other words, they will understand the prayer interiorly if not in words. Since hearing that, I have always thought it important to play and pray music related to a relevant text. This is not an excuse for laziness and to not provide texts in worship aids. But in times when texts are not readily available, or even if they are, the liturgical understanding is not present, one relies on faith that what the musician prays edifies and transports those with open ears open to prayer.

Another friend recently wrote to me, “I don’t think that the average Catholic has a conscious appreciation of our need for sacred mystery.” However, I believe that there might be a subconscious hunger for the sacred mysteries. While this may sound silly to some of us, it is worth the reminder to never be afraid of expressing mystery. Improvisation does this quite well as it unleashes the spirit. Coupled with Gregorian Chant, improvisation gives further voice to the sacred. Do not be afraid of the mystery!

ERE I OFFER TWO somewhat random examples from the twenty-third Sunday in Ordinary Time. While crude videos, they were recorded during mass, hopefully retaining the continuity of the liturgical action. In somewhat of a colorful French, yet modal language, I hope my limited improvisational skills assist in prayer.

Hopefully, if we make a habit of keeping the prayers of the propers in our hearts, we will ourselves become converted and transformed in the ways we most need. This in turn may assist in all the other work that we must do.

There is power in improvisation and in prayer.

    PDF • “Music List” (4th Sunday of Advent)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 21 December 2025, which is the 4th Sunday of Advent (Year A). If such a thing interests you, feel free to download it as a PDF file. The ENTRANCE CHANT is the famous “Roráte Coeli” and the fauxbourdon setting of the COMMUNION is exquisite. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

    PDF • Our Lady of Guadalupe (12 Dec.)
    The Responsorial Psalm may be downloaded as a PDF file (organist & vocalist) for 12 December, which is the Feast of Our Lady of Guadalupe. When it comes to the formulary for this Mass, it’s astounding how infrequently it’s included in official books. Prior to Vatican II, one had to search through “supplemental material” printed in the back of hand-missals and graduals. But since 1970, the feast is virtually nonexistent. According to the UNIVERSAL KALENDAR, 12 December is the “Feast of Saint Jane Frances De Chantal, Religious” (Die 12 decembris: S. Ioannæ Franciscæ de Chantal, religiosæ). Why should that feast overpower Our Lady of Guadalupe? In the United States, OLG is celebrated—and I’d assume in Mexico, Central America, South America, and Canada—but, as I said, the Propria Missae are virtually impossible to locate. I possess only three books which mention this feast.

    Simplified Accompaniment (Advent Hymn)
    Many organists are forced to simultaneously serve as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult. I invite you to download this simplified organ accompaniment (PDF) which in the Father Brébeuf Hymnal is hymn #661: “Come, Thou Long-Expected Jesus” (for ADVENT). I’m toying with the idea of creating a whole bunch of these, to help amateur organists. The last one I uploaded was downloaded more than 2,900 times in a matter of hours—so there appears to be interest.

Quick Thoughts

    PDF Download • “Santo Santo Santo”
    Those searching for a dignified, brief, simple, bright setting of SANCTUS in Spanish (“Santo Santo Santo”) are invited to download this Setting in honor of Saint John Brébeuf (organist & vocalist). I wonder if there would be any interest in me recording a rehearsal video for this piece.

    Pope Leo XIV on Sacred Music
    On 5 December 2025, Pope Leo XIV made this declaration with regard to liturgical music.

    “Translations Approved for Liturgical Use”
    According to the newsletter for USSCB’s Committee on Divine Worship dated September 1996, there are three (3) translations of the Bible which can be used in the sacred liturgy in the United States. You can read this information with your own eyes. It seems the USCCB and also Rome fully approved the so-called NRSV (“New Revised Standard Version”) on 13 November 1991 and 6 April 1992 but this permission was then withdrawn in 1994.

Random Quote

“Liberalism in religion is the doctrine that there is no positive truth in religion, but that one creed is as good as another… It teaches that all are to be tolerated, for all are matters of opinion. Revealed religion is not a truth, but a sentiment and a taste; not an objective fact, not miraculous; and it is the right of each individual to make it say just what strikes his fancy. […] Men may go to Protestant Churches and to Catholic, may get good from both and belong to neither.”

— Bl. John Henry Cardinal Newman (May of 1879)
