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.

    “Music List” • 19th in Ordinary Time (Year C)
    Some have expressed interest in perusing the ORDER OF MUSIC I prepared for the 19th Sunday in Ordinary Time (10 August 2025). 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 feasts website.

    This Sunday’s Communion Antiphon
    This coming Sunday—10 August 2025—is the 19th Sunday in Ordinary Time (Year C). The COMMUNION ANTIPHON is really gorgeous, and two of its features are worth mentioning. First of all, the Gospel reading assigned is from Saint Luke, whereas the the antiphon—although it matches the account—comes from Saint Matthew. (If anyone can point to a similar example, please notify me.) Furthermore, if you look at the authentic Gregorian Chant version posted on the feasts website, you’ll notice that it’s MODE III but ends on the ‘wrong’ note. A comparable instance of such a ‘transposed’ chant would be KYRIE IV.

    Using “Ye” Vs. “You” Correctly
    Using “Ye” vs. “You” is rather tricky, because it depends upon which era one is trying to recreate—if that makes any sense. In other words, the rules haven’t always been the same for these two. Nevertheless, Father Philip George Caraman (the legendary Jesuit scholar) gives us a masterclass using Saint Luke’s Gospel. Father Caraman was close friends with Monsignor Ronald Knox, Evelyn Waugh, and Sir Alec Guinness.

Quick Thoughts

    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.

    Antiphons Don’t Match?
    A reader wants to know why the Entrance and Communion antiphons in certain publications deviate from what’s prescribed by the GRADUALE ROMANUM published after Vatican II. Click here to read our answer. The short answer is: the Adalbert Propers were never intended to be sung. They were intended for private Masses only (or Masses without music). The “Graduale Parvum,” published by the John Henry Newman Institute of Liturgical Music in 2023, mostly uses the Adalbert Propers—but sometimes uses the GRADUALE text: e.g. Solemnity of Saints Peter and Paul (29 June).

Random Quote

When you consider that the greatest hymns ever written—the plainchant hymns—are pushing the age of eight hundred and that the noble chorale hymn tunes of Bach date from the early eighteenth century, then what is the significance of the word “old” applied to “Mother at Thy Feet Is Kneeling”? Most of the old St. Basil hymns date from the Victorian era, particularly the 1870s and 1880s.

— Paul Hume (1956)
