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.

    PDF Download • “Organ Accompaniment”
    Over the past few years, I’ve been harmonizing all the vernacular plainsong Introit settings by the CHAUMONOT COMPOSERS GROUP. This coming Sunday—10 May 2026—is the 6th Sunday of Easter (Year A). The following declaration will probably smack of “blowing my own horn.” However, I’d rank this accompaniment as my best yet. In this rehearsal video, I attempt to sing it while simultaneously accompanying myself on the pipe organ. The musical score [for singers] as well as my organ accompaniment can be downloaded free of charge from the flourishing feasts website.

    “Gregorian Chant Quiz” • 4 May 2026
    A few days ago, the CORPUS CHRISTI WATERSHED Facebook page posted this Gregorian Chant quiz regarding a rubric for the SEQUENCE for the feast of Corpus Christi: “Lauda Sion Salvatórem.” There is no audience more intelligent than ours—yet surprisingly nobody has been able to guess the rubric. Drop me an email with the right answer, and I’ll affirm your brilliance to everyone I encounter!

    “Rare Photographs” • Hannibal Bugnini
    On 2 September 2025, we included in this article extremely rare photographs of Archbishop Hannibal Bugnini taken in Iran circa 1979. Bugnini had initially been banished by the pope to Uruguay, but he refused to obey. [This is interesting, since Bugnini relied upon ‘blind obedience’ when it came to modifications of the ancient liturgy.] After he refused to obey the order from the pope, Hannibal Bugnini was banished to Iran. You can also watch a short video of Hannibal Bugnini in Iran, dated 10 November 1979. That’s about a week after the USA embassy hostage crisis began in Tehran, and Pope Saint John Paul II had sent the leader of the Iranian Revolution a special letter.

Quick Thoughts

    Simplified Version • “Canon in D” (Pachelbel)
    I published an article on 11 November 2023 called Wedding March For The Lazy Organist, which rather offhandedly made reference to a simplified version I created in 2007 for Pachelbel’s Canon. I often use it as a PROCESSIONAL for weddings and quinceañeras. Many organists say they “hate” Pachelbel’s Canon. But I love it. I think it’s bright and beautiful. I created that ‘simplified version’ for musicians coming to grips with playing the pipe organ. It can be downloaded as a free PDF if you visit Andrea Leal’s article dated 15 August 2022: Manuals Only: Organ Interludes Based on Plainsong. Specifically, it is page 84 in that collection—generously offered as a free PDF download. Johann Pachelbel (d. 1706) was a renowned German organist, violinist, teacher, and composer of over 500 works. A friend of Bach’s family, he taught Johann Christoph Bach (Sebastian Bach’s eldest brother) and lived in his house. Those who read Pachelbel’s biography will notice his connection to two German cities adopted as famous hymn tune names: EISENACH and ERFURT.

    PDF Download • “Anima Christi”
    I received a request for an organ accompaniment I created way back in 2007 for the “Anima Christi” Gregorian Chant. You can download this PDF file which has the score in plainsong followed by a keyboard accompaniment. Many melodies have been paired with “Anima Christi” over the centuries, but this is—perhaps—the most common one.

    PDF • “Liturgical Law” (467 Pages)
    On Good Friday during the middle ages, the pope privately recited THE ENTIRE PSALTER. If you don’t believe me, see for yourself by reading this passage by Dom Charles Augustine Bachofen (d. 1943). His famous book—called “Liturgical Law: A Handbook Of The Roman Liturgy”—was published by the Benjamin Herder Book Company, which was the American arm (operating out of St. Louis, Missouri) of one of the world’s most significant Catholic publishers. Dom Charles Augustine Bachofen was born in Switzerland but spent his career between the Benedictine monasteries at Conception (Missouri) and Mount Angel (Oregon). His 1931 masterpiece, Liturgical Law can be downloaded as a PDF file … 467 pages!

No concession should ever be made for the singing of the Exsultet, in whole or in part, in the vernacular.
