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.”

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.

    Cardinal Ranjith on “Active Participation”
    From 2005–2009, Malcolm Cardinal Ranjith served as Secretary of the Congregation for Divine Worship and the Discipline of the Sacraments. He was considered ‘papabile’ during the last conclave. On 8 December 2008, he wrote this powerful statement concerning Gregorian Chant, participatio actuosa, celebration “ad orientem,” and other subjects. When it comes to the question of what “sacred” means, Monsignor Robert A. Skeris provides a marvelous answer.

    “Music List” • 22nd in Ordinary Time (Year C)
    Some have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 31 August 2025, which is the 22nd Sunday in Ordinary Time (Year C). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are conveniently stored at the spectacular feasts website alongside the official texts in Latin.

    “The Worm That Dieth Not”
    My pastor asked me to write a column for our parish bulletin with reflections on the sacred liturgy and church music. In my most recent article, I discuss “The Worm That Dieth Not.” At this website, you can access it conveniently; simply scroll down to the one dated 31 August 2025.

Quick Thoughts

    Solemn “Salve Regina” (Chant)
    How many “S” words can you think of using alliteration? How about Schwann Solemn Salve Score? You can download the SOLEMN SALVE REGINA in Gregorian Chant. The notation follows the official rhythm (EDITIO VATICANA). Canon Jules Van Nuffel, choirmaster of the Cathedral of Saint Rumbold, composed this accompaniment for it (although some feel it isn’t his best work).

    Pope Pius XII Hymnal?
    Have you ever heard of the Pope Pius XII Hymnal? It’s a real book, published in the United States in 1959. Here’s a sample page so you can verify with your own eyes it existed.

    “Hybrid” Chant Notation?
    Over the years, many have tried to ‘simplify’ plainsong notation. The O’Fallon Propers attempted to simplify the notation—but ended up making matters worse. Dr. Karl Weinmann tried to do the same in the time of Pope Saint Pius X by replacing each porrectus. You can examine a specimen from his edition and see whether you agree he complicated matters. In particular, look at what he did with éxsules fílii Hévae.

Random Quote

And since it is becoming that holy things be administered in a holy manner, and of all things this sacrifice is the most holy, the Catholic Church, to the end that it might be worthily and reverently offered and received, instituted many centuries ago the holy canon, which is so free from error that it contains nothing that does not in the highest degree savor of a certain holiness and piety and raise up to God the minds of those who offer.

— Council of Trent (1562)
