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.”

PDF Download • “Marian Antiphon Booklet” (4 pages) + Five Rhythmic Considerations

Jeff Ostrowski · October 22, 2025

T WOULD BE dimwitted to attack a rhinoceros for having a neck shorter than a giraffe’s. Similarly, it’s foolish to attack the Brébeuf Hymnal for having different contents than the Liber Cantualis, Parish Book of Chant, or Cantus Varii. The reason is because the BRÉBEUF HYMNAL is dedicated to singable, metrical, vernacular hymns. It doesn’t contain orchestral parts, polyphony, readings, violin scores, lives of the saints, or copious plainsong because such material would be extraneous. Each parish will have unique desires, and my current parish is no different. I’m preparing stickers to be placed inside the covers of each Brébeuf Hymnal as a supplement. Our pastor wants each member of the congregation to learn the Marian antiphons. I also included several settings of the KÝRIE our parish will be learning:

Thank you very much!

Brief Overview • For Marian antiphons which are more unfamiliar, I included metrical (“singable”) English translations just in case. I’m almost finished creating organ accompaniments for each chant in this booklet. As soon as they’re complete, I’ll release them online. [Because it contains all the different settings of the KÝRIE, this will be a handy collection to keep on your organ bench.] When it comes to the rhythm of the Marian antiphons, I tried to take into consideration various “schools,” not just the French approach (see below).

I’m the last person who desires “change for the sake of change.” On the other hand, each musician has core beliefs which can’t be violated. In this regard, I’m no different than anyone else. Even though certain editions have become popular, they violate my musical sensitivities. I simply can’t use them. Here’s one example:

To violate what I know to be true and right isn’t an option for me. I take comfort in the fact that Dom Pothier agrees.

(1 of 5) Rhythmic Considerations • Readers who have assiduously followed our blog will recall that Dom André Mocquereau ‘hijacked’ the rhythm of the official edition published by Pope Saint Pius X. In 2013, Dr. Katharine Ellis of Cambridge University published a letter she discovered which suggests Dom Mocquereau’s modifications (“value-added”) were done for financial gain—but others feel the matter wasn’t quite so straightforward. Regardless, because the French language places the accent on the final syllable of each word, Dom Mocquereau wanted to do the same with plainsong. For example, look at the way Dom Mocquereau treated GLORIA IX:

*  PDF Download • COMPARISON CHART (Gloria IX)
—Dom Mocquereau adds elongations where they don’t belong.

Many rhythmic modifications by Dom Mocquereau were an attempt to elongate the final syllable, as if the words were French. For example, look at what Dom Mocquereau does to AGNUS DEI IV, stretching out the final syllable of “miserére” for no discernible reason whatsoever. Or, consider the following specimen, wherein “id-í-psum” is proper pronunciation:

Whereas German editions have no problem marking the rhythm properly:

(2 of 5) Rhythmic Considerations • It took me twenty years to finally break free of Dom Mocquereau’s rhythmic modifications. They are technically forbidden—but that’s not why I stopped using them. They aren’t justifiable from a musicological standpoint (since they purport to reflect less than 0.03% of plainsong manuscripts)—but that isn’t why I stopped. They make the score look ugly and busy—but that’s not why I stopped. I finally abandoned Dom Mocquereau’s modifications because (for half a decade) our parish sang VESPERS (1962) each Sunday. Dom Mocquereau added so many elongations, it became utterly absurd.

(3 of 5) Rhythmic Considerations • Even if I wanted to, I can never return to singing like this, because the chant becomes heavy, funereal, and plodding. Indeed, it is sometimes called “neo-mensuralist” because Dom Mocquereau’s alterations make the singing resemble longs and shorts.

(4 of 5) Rhythmic Considerations • If one sings according to Dom Mocquereau for many years, one will see one’s Latin deteriorate. One begins to believe the word is “pórtare”—whereas the correct pronunciation is portáre. I remember meeting a Mocquereau disciple who erroneously believed the Easter Sequence was pronounced “Victímæ páschalí laudés.” When we look at Dom Mocquereau’s alterations, can we blame him? Or consider the COMMUNION (Mitte manum tuam) on Low Sunday. If one sings long enough—pardon the pun—according to Dom Mocquereau, one begins to mispronounce clavórum as “clavorúm.” This is not good.

(5 of 5) Rhythmic Considerations • When the Vatican Commission on Gregorian Chant (which was assembled by Pope Saint Pius X) published the EDITIO VATICANA, they decided to avoid micromanaging the rhythm in syllabic chant. The committee’s president, Abbat Joseph Pothier, realized that each country had a slightly different way of singing. When it comes to the simple versions of the MARIAN ANTIPHONS, this has created confusion. The root cause is something we have called “Trochee Trouble.” It would take too long to explain “Trochee Trouble” in detail … but it basically refers to how Germans tend to emphasize the tonic accent on every trochee, whereas the French tend to deëmphasize the tonic accent. Because Dom Mocquereau spent most of his life in an English monastery (owing to the French anti-clerical laws), Americans are usually only familiar with the “French” method.

(A) German Hymnal • Consider this example, taken from a 20th-century German hymnal. Many Americans would be surprised to see this! Note their treatment of “coeli.”

(B) German Hymnal • Here’s another 20th-century German hymnal. Again, take note—pardon the pun—of their treatment of the word “cæli.”

(C) German Hymnal • Here’s a third example, taken from a 20th-century German hymnal. Please carefully examine what they do with each trochee:

(D) German Hymnal • Here’s another example from a 20th-century German hymnal. Again, notice the treatment of each trochee:

(E) German Hymnal • Many Americans would be surprised by this because (as I have mentioned already) many are familiar with Dom Mocquereau’s rhythm only:

(F) German Hymnal • When it comes to “Trochee Trouble,” the Ave Regína Cælórum illustrates the matter so well:

    Simplified Accomp. • Schubert’s “Ave Maria.”
    Sometimes the organist must simultaneously serve as the CANTOR. (Those who work in the field of church music know exactly what I’m talking about.) One of our contributors composed this simplified keyboard accompaniment for Franz Schubert’s “Ave Maria,” a piece which is frequently requested for Catholic funerals and weddings. In terms of the discussion about whether that piece is too theatrical (‘operatic’) for use in Church, I will leave that discussion to others. All I know is, many church musicians out there will appreciate this simplified version.

    Simplified Accompaniment (Easter Hymn)
    Number 36 in the Brébeuf Hymnal is “At the Lamb’s high feast we sing,” an English translation for Ad Cenam Agni Próvidi (which was called “Ad Régias Agni Dapes” starting 1631). As of this morning, you can download a simplified keyboard accompaniment for it. Simply click here and scroll to the bottom. Many organists are forced to serve simultaneously as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult—which explains why choirmasters appreciate these simplified keyboard accompaniments. Sadly, many readers will click that link but forget to scroll to the bottom where the simplified PDF file is located.

Quick Thoughts

    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!

    “Gregorian Chant Quiz” • 24 March 2026
    How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!

Random Quote

“…I started down the road of the liturgy, and this became a continuous process of growth into a grand reality transcending all particular individuals and generations, a reality that became an occasion for me of ever-new amazement and discovery. The incredible reality of the Catholic liturgy has accompanied me through all phases of life, and so I shall have to speak of it time and again.”

— Joseph Cardinal Ratzinger
