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.”

Can Polyphony Be Added to the Ordinary Form?

Jeff Ostrowski · January 29, 2025

HEN HOLY JESUITS like Father John Brébeuf came to America, they had no roadmap to follow. Father Brébeuf never thought of himself as a linguist. Yet, he ended up spending countless hours deciphering the native languages and creating a Montagnais dictionary as well as a Huron phrase-book, dictionary, catechism, and grammar. Dr. John A. O’Brien said “Brébeuf’s pioneer studies of the Huron and Petun languages laid the foundation for most subsequent work in these tongues.” In a moment, I’ll explain why I bring this up.

Ordinary Form • Vatican II was clear and explicit when it comes to the THESAURUS MUSICAE SACRAE. Specifically, Vatican II said the THESAURUS “must be preserved and fostered with great care.” Even someone who’s 95% brain-dead can easily comprehend those words. There’s no ambiguity—no wiggle room. Vatican II also gave this mandate: “choirs must be diligently promoted.” Technically, that statement is superfluous because the THESAURUS is choral music. By way of analogy, if I were to order you to perform a bassoon sonata, “fingers and mouth” are clearly required.1

Below are two ‘live’ recordings of my choir singing CHORAL EXTENSIONS. Since these were recorded during our parochial Mass on Sunday, you can hear babies crying and pews slamming:

*  Mp3 Download • HOSANNA CHORAL EXTENSION—‘live’ recording
—Rehearsal videos and score are #29982.

*  Mp3 Download • KYRIE with Extension—by Willam Byrd
—‘Live’ recording by a volunteer choir.

Of course, improvement can always be made. On the other hand, our choir has existed for less than five months—and I feel we’ve made good progress. My wife snapped this photograph after Christmas Midnight Mass:

Conclusion • In spite of the overly-explicit language we just examined, many priests and bishops claim Vatican II outlawed choirs, polyphony, and Latin. Therefore—just like Father Brébeuf—we have to be “creative” or “imaginative” or “enterprising” in how we add polyphony to the Ordinary Form. Using CHORAL EXTENSIONS is one excellent way! We will talk more about this during the 2025 Sacred Music Symposium. Very soon, we’ll be opening up registration: Stay tuned!

1 Nevertheless, I’m glad the Second Vatican Council went out of its way to be explicit (“choirs must be diligently promoted”) in case some idiot wanted to pretend the THESAURUS MUSICAE SACRAE could be “preserved and fostered with great care” without choirs.

    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.

“We must strip from our Catholic prayers and from the Catholic liturgy everything which can be the shadow of a stumbling block for our separated brethren—that is, for the Protestants.”
