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.”

Jeff Ostrowski · November 20, 2022

HOSE WHO SING the Vatican Edition according to the “official rhythm” will see that this is the most natural rendering. After all, the commission which created the official rhythm wanted it to be sung a particular way. On 18 February 1910, the PREFECT of the Congregation of Sacred Rites wrote a letter saying: “the rhythmical form of the melodies […] is inseparable from the edition itself.” But Dom Mocquereau eliminated elongations which should be there (and added elongations which don’t belong). Not infrequently, Mocquereau’s modifications greatly alter the melody—and a perfect illustration is ALLELUIA: Éripe me, which comes from the 9th Sunday after Pentecost. Play through the examples, and you’ll agree the melody was distorted by Mocquereau.

“What Does It Sound Like?” • On the other hand, one can point to large swaths of the repertoire which Dom Mocquereau seemed hesitant to modify. For example, listen to the following INTROIT, recorded last Sunday by our (100% volunteer) parish choir. It was sung according to the official rhythm and required a grand total of 15 minutes rehearsal time:

Trochee Trouble • The official edition provides a certain amount of freedom for choirmasters when it comes to trochee endings. We have discussed this at length: cf. Trochee Trouble. For Mode 6 psalmody, Germans elongate the final Trochee. Below is an example of how that sounds. I have to admit, the German way is quite lovely—or is that merely because I’m not used to it?

Exciting PDF Files! • Please feel free to download three (3) professionally-scanned editions of the KYRIALE. These are tremendously important from the standpoint of music history. They adhere to the official rhythm—the so-called “pure” Editio Vaticana.

Jeff Repeating Himself • The entire KYRIALE contains only a handful of MMVs (Melismatic Morae Vocis), and I’ve repeated this statement frequently. Practically speaking, due to the paucity of MMVs, the KYRIALE editions by Dom Mocquereau are—in many ways—identical to the official rhythm. Katharine Ellis cited evidence suggesting that Prior André Mocquereau may have had a financial incentive to “put as many rhythmic signs as possible in the Graduale and in the Antiphonale,” but more research needs to be done in this area to ascertain the truth. My colleague, Professor Weaver, is writing a doctoral dissertation on Dom Mocquereau’s rhythmic theories, and it will be interesting to read what he has to say vis-à-vis some of the letters Katharine Ellis dug up.

Example From Kyrie IV • Notice I said “only a handful of MMVs.” I did not claim the KYRIALE was completely devoid of MMVs. Therefore, let’s examine an MMV from Kýrie Cunctípotens Génitor Deus (Mass IV). Towards the end of the piece, we observe a pattern which clearly 1 contains a white space equal to a notehead. That indicates where the mora vocis (“elongation”) belongs. The 1905 Schwann edition does it perfectly:

The 1905 Styria edition also indicates the MMV perfectly:

The Nóva órgani harmónia (Lemmensinstituut, 1940s) marks the MMV perfectly:

The 1909 Schwann edition in modern notation marks the MMV perfectly:

The 1914 edition in modern notation by Max Springer indicates the MMV, although in a slightly ‘funky’ way:

The 1906 organ accompaniment by Monsignor Nekes manifests no difficulty marking the MMV:

Nor does Father Mathias have any difficulty marking the MMV:

I’ve often remarked that Dr. Peter Wagner’s organ accompaniments are an abomination. Not only are the harmonies awful, but he’s quite careless when it comes to the MMVs. Once again, we see an inexplicable treatment of the Editio Vaticana MMV by Dr. Peter Wagner:

For the record, you can examine the version by Dr. Wagner published in 1904 (before the Editio Vaticana was released):

The Editio Vaticana was based on the Liber Gradualis published in 1883 by Dom Pothier at the monastery of Solesmes. For the sake of curiosity, we can examine the 1883 version and see that Abbat Pothier seems to have intended an MMV at that time—although we also remember that his “white spaces” in 1883 were the subject of criticism, in terms of how they tended to be ambiguous:

We see that Dom Mocquereau had an elongation at the same spot in his 1903 Liber Usualis, released just two years (!) before the Editio Vaticana was published:

“Mr. Contrary” • Dom Mocquereau—when he added his rhythmic markings to the Editio Vaticana KYRIALE—“disregards” or “ignores” or “eliminates” this MMV. I don’t see why he found it so difficult to place an MMV where it belongs, as he had done in 1903. To me, it almost seems as if his intention was to foment confusion:

If someone doubts whether Dom Mocquereau intended to contradict the official rhythm, let him examine the 1905 Solesmes edition of the KYRIALE. Writing in December of 1905, Dom Mocquereau explicitly says: “Blank spaces in this edition never indicate morae vocis.” Indeed, that’s the only time I know of Dom Mocquereau ever signing his name to any of the Solesmes edition prefaces. When the Congregation for Sacred Rites discovered the rhythmic alterations, they withdrew their approbation, but said books which had already been printed could remain in circulation.

To Be Continued • A hundred years ago, I can understand why somebody would avoid the Mechlin edition or the Pustet edition. Both were printed using very small fonts, and the MMV were difficult to locate. But in the year 2022, our technology can easily solve that issue. I have been asking my colleagues what they find so terrible about the official rhythm. So far, I have not received an answer. Why not sing the Editio Vaticana as it was intended to be sung? I will continue to seek an answer to this question!

1 Several printers had difficulty understanding how to print the instances of MMV (Melismatic Mora Vocis) when the inaugural section of the Editio Vaticana was released in 1905. For example, if you download the 1905 edition by Lecoffre, you will notice its editor erroneously forgot to include the MMV we’re discussing. The Vatican printer, Mr. Scotti, therefore sent out this letter on 6 September 1906. The letter clarified the obligatory MMVs.

    New Bulletin Article • “12 October 2025”
    My pastor requested that I write short articles each week for our parish bulletin. Those responsible for preparing similar write-ups may find a bit of inspiration in these brief columns. The latest article (dated 12 October 2025) talks about an ‘irony’ or ‘paradox’ with regard to 1960s switch to vernacular in the liturgy.

    “Reminder” — Month of October (2025)
    Those who don’t sign up for our free EMAIL NEWSLETTER miss important notifications. Last week, for example, I sent a message about this job opening for a music director paying $65,000 per year plus benefits (plus weddings & funerals). Notice the job description says: “our vision for sacred music is to move from singing at Mass to truly singing the Mass wherein … especially the propers, ordinaries, and dialogues are given their proper place.” Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

    “Music List” • 27th in Ordinary Time (Year C)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 5 October 2025, which is the 27th 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. Readers will want to check out the ENTRANCE CHANT posted there, which has a haunting melody (in the DEUTERUS MODE) and extremely powerful text.

Quick Thoughts

    “American Catholic Hymnal” (1991)
    The American Catholic Hymnal, with IMPRIMATUR granted (25 April 1991) by the Archdiocese of Chicago, is like a compendium of every horrible idea from the 1980s. Imagine being forced to stand all through Communion (even afterwards) when those self-same ‘enlightened’ liturgists moved the SEQUENCE before the Alleluia to make sure congregations wouldn’t have to stand during it. (Even worse, everything about the SEQUENCE—including its name—means it should follow the Alleluia.) And imagine endlessly repeating “Alleluia” during Holy Communion at every single Mass. It was all part of an effort to convince people that Holy Communion was historically a procession (which it wasn’t).
    —Jeff Ostrowski
    “Canonic” • Ralph Vaughan Williams
    Fifty years ago, Dr. Theodore Marier made available this clever arrangement (PDF) of “Come down, O love divine” by P. R. Dietterich. The melody was composed in 1906 by Ralph Vaughan Williams (d. 1958) and named in honor of of his birthplace: DOWN AMPNEY. The arrangement isn’t a strict canon, but it does remind one of a canon since the pipe organ employs “points of imitation.” The melody and text are #709 in the Brébeuf Catholic Hymnal.
    —Jeff Ostrowski
    Did they simplify these hymn harmonies?
    Choirs love to sing the famous & splendid tune called “INNSBRUCK.” Looking through a (Roman Catholic) German hymnal printed in 1952, I discovered what appears to be a simplified version of that hymn. In other words, their harmonization is much less complex than the version found in the Saint Jean de Brébeuf Hymnal (which is suitable for singing by SATB choir). Please download their 1952 harmonization (PDF) and let me know your thoughts. I really like the groovy Germanic INTRODUCTION they added.

Random Quote

“After a discussion lasting several days, in which arguments for and against were discussed, the Council fathers came to the clear conclusion—wholly in agreement with the Council of Trent—that Latin must be retained as the language of cult in the Latin rite, although exceptional cases were possible and even welcome.”
