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.

President’s Corner

    “Samaritánæ” (3rd Sunday of Lent)
    With regard to the COMMUNION for the 3rd Sunday of Lent (Year A), the Ordo Cantus Missae—which was published in 1969 by the Vatican, bearing Hannibal Bugnini’s signature and approbation in its PREFACE—inexplicably introduced a variant melody and slightly different words, as you can see by this comparison chart. When it comes to such items, they’re always done in secrecy by unnamed people. (Although it is known that Dom Eugène Cardine collaborated in the creation of the GRADUALE SIMPLEX, a book considered by some to be a travesty.)

    PDF Download • “Ubi Caritas” (SATB)
    I remember singing “Ubi Cáritas” by Maurice Duruflé at the conservatory. I was deeply moved by it. However, some feel Duruflé’s version isn’t suitable for small choirs since it’s written for 6 voices and the bass tessitura is quite low. That’s why I was absolutely thrilled to discover this “Ubi cáritas” (SATB) for smaller choirs by Énemond Moreau, who studied with OSCAR DEPUYDT (d. 1925), an orphan who became a towering figure of Catholic music. Depuydt’s students include: Flor Peeters (d. 1986); Monsignor Jules Van Nuffel (d. 1953); Arthur Meulemans (d. 1966); Monsignor Jules Vyverman (d. 1989); and Gustaaf Nees (d. 1965). Rehearsal videos for each individual voice await you at #19705. When I came across the astonishing English translation for “Ubi Cáritas” by Monsignor Ronald Knox—matching the Latin’s meter—I decided to add those lyrics as an option (for churches which have banned Latin). My wife and I made this recording to give you some idea how it sounds.

    PDF • “Cantus Mariales” (192 pages)
    Andrea Leal has posted an absolutely pristine scan of CANTUS MARIALES (192 pages) which can be downloaded as a PDF file. To access this treasure, navigate to the frabjous article Andrea posted Monday. The file is being offered completely free of charge. The beginning pages of the book have something not to be missed: viz. a letter from Pope Saint Pius X to Dom Pothier, in which the pope calls Abbat Pothier “a man versed above all others in the science of liturgy, and to whom the cause of Gregorian chant is greatly indebted.”

Quick Thoughts

    Grotesque Pairing • “Passion Chorale”
    One of our rarest releases was undoubtably this PDF scan of the complete Pope Pius XII Hymnal (1959) by Father Joseph Roff, a student of Healey Willan. One of the scarcest titles in existence, this book was provided to us by Mr. Peter Meggison. Back in 2018, we scanned each page and uploaded it to our website, making it freely available to everyone. Readers are probably sick of hearing me say this, but just because we upload something that doesn’t necessarily mean it’s wonderful or worthy of imitation. We upload many publications precisely because they are ‘grotesque’, interesting, or revealing. Whereas the Brébeuf Catholic Hymnal had an editorial board that was careful and sensitive vis-à-vis pairing texts with tunes, the Pope Pius XII Hymnal (1959) seems to have been rather reckless in this regard. Please take a look at what they did with the PASSION CHORALE and see whether you agree.

    Extreme Unction
    Those who search Google for “CCCC MS 079” will discover high resolution images of a medieval Pontificale (“Cambridge, Corpus Christi College, MS 079”). One of the pages contains this absolutely gorgeous depiction of the Sacrament of Extreme Unction.

    PDF Chart • “Plainsong Rhythm”
    I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”

Random Quote

“To me it is a most inspiring reflection that, while empires and kingdoms have tumbled down, while language and custom of every kind have changed beyond recognition, still day by day the humblest Catholic priest in the remotest mission stands at his altar dressed in the garb of old Rome.”

— Father Adrian Fortescue (8 February 1912)
