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.”

Gregorian Rhythm Wars • “Jeff’s Second Response to Patrick” (6 Dec 2022)

Jeff Ostrowski · December 6, 2022

Gregorian Rhythm Wars contains all previous installments of our series.

ROWING UP DURING the 1990s, my siblings would sometimes play a game called CLUE. To win this game, one player would stand up and say something like: “I accuse Colonel Mustard in the library with the lead pipe.” My dear Mr. Williams, today I have the solemn duty of accusing you! I accuse you of muddying the waters by broaching way too many topics, instead of—with restraint—responding meticulously to the specific issues in a straightforward way. (Needless to say, readers will judge the veracity of my accusation.) The saintly Father Valentine Young gently criticized newly-ordained priests: “When they get up to preach, they feel like they have to recite everything they’ve ever learned.” I urge you not to succumb to the same temptation! Let us proceed slowly. The readers will appreciate that.

Some Good News • It may not seem like it, but we’ve made some progress. I have assembled a list—albeit a short one—indicating items we agree upon. Because we already agree on those, we no longer need to argue about them. Whenever I notice more items, I’ll add them to the list. I refuse to pursue the numerous rabbit holes you’ve broached, because doing so would ruin our series. For instance, on 30 November 2022 you made a statement (“for the traditional Latin Mass […] chant renditions in the style of Eugène Cardine or Marcel Pérès are acceptable”) and explicitly said your statement is “a fact, not an opinion.” I could demonstrate your statement is erroneous; indeed, several reasons are provided here. But all those rabbit holes will have to wait.

The Point of My Article Today • I promised that—whenever feasible—I would respond to your specific charges. In your recent article, you attempted to show that I made erroneous statements. As a matter of fact, my assertions were were right on the money. Today, I will conclusively prove this, so we can advance to what you promised. Remember, you promised to give evidence showing I “misread” (your word) elongations in the famous 47CHARTRES|957 manuscript. [To jog your memory, click here and scroll down to the paragraph called “11 November B.”]

Setting the Stage • We both agree that plainsong was sung—broadly speaking—the same way for many centuries: let’s say (roughly) from 975AD to 1550AD and from 1880AD until Vatican II. At this point, I am neither admitting nor denying that plainsong was sung “with longs and shorts” before 975AD. For the sake of argument, let’s just assume your view is correct. Below, I painstakingly demonstrate that virtually all the manuscript evidence contradicts this, yet those same manuscripts (somehow?) managed to transmit the pitches with astounding accuracy. Even more importantly, the scribes never betray the ‘true’ rhythm—even by accident! Needless to say, the handful of manuscripts which I have labelled lightheartedly as “MOC’S FANTASTIC FOUR” are exceptions. Those are the group of manuscripts generally thought to be slightly older than the rest. Dom Mocquereau and you, Mr. Williams, share a special predilection for these manuscripts. Indeed, in your view, all the other manuscripts are utterly worthless when it comes to rhythm. You look upon these thousands of manuscripts in much the same way that I view the plainsong editions of Guillaume-Gabriel Nivers.

“Specimen” Reminder • In my inaugural article, I declared that my “specimen” was going to be the INTROIT for the 22nd Sunday after Pentecost [Ordinary Form: 28th Sunday in Ordinary Time]. Dom Mocquereau claims we obtain the “truly traditional reading” if we contradict the official edition by adding episemata shown in the following graphic:

Mr. Patrick Mocquereau? • By choosing this specimen, my dear Mr. Patrick Williams, I was not claiming that you embrace, adopt, or endorse everything Dom Mocquereau says. I readily acknowledge that you don’t (although you do cite him as an expert). The reality is, for 100+ years people have been told that adding Mocquereau’s signs makes the chant “more authentic.” You realize how pervasive the editions of Dom Mocquereau are, Mr. Williams. More importantly, you—like Dom Mocquereau—subscribe to the general theory or belief that the ‘true’ rhythm of plainsong was “lost” or “abandoned” or “forgotten” or “discarded” sometime around 950AD. Therefore, the specimen I chose strikes me as eminently fair to discuss—and you have done precisely that in subsequent articles … so don’t stop now!

We Need Evidence! • As I explained in my inaugural article, it’s difficult to accept the assertion that plainsong’s ‘true’ rhythm was somehow forgotten. Firstly, there’s too much contradiction between the so-called “rhythmic” manuscripts. Secondly, contemporaneous musicians would have made reference to this supposed abandonment of the ‘true’ rhythm—and we have virtually no examples of that. [The quote attributed to ARIBO circa 1070AD hardly settles the question since it’s quite vague and never defines what “a long time” means.] Thirdly, if there truly was an enormous “rhythmic decay”—using Dom Gregory Murray’s term—of the ‘true’ tradition, there ought to be transitional manuscripts giving evidence of such a decay. Finally, it’s extremely difficult to accept the notion that thousands of later MSS transmitted the plainsong pitches with superb accuracy, yet completely wrecked the plainsong rhythm. It’s even harder to accept the assertion that all the diastematic notation “pristinely wrecked” the rhythm—that is to say, not once (!) ever wrecking the rhythm in such a way that the ‘true’ rhythm was betrayed, revealed, or hinted at … even by accident.

Jeff’s Evidence:

I have stated that—without a doubt—we can be certain the 30+ manuscripts I meticulously cited contradict Dom Mocquereau’s elongations because of internal evidence. In other words, one simply has to compare “apples-to-apples” (like observáveris or iniquitátes) and the truth is easily discerned. To my genuine surprise, Mr. Williams, you challenged this notion! Therefore, I will conclude my article by giving examples from the manuscripts themselves. If I had time, I would add all 30+ manuscripts. But I don’t have time for that—so what I’ve included (below) will have to suffice. I assure you, I could easily add another 40 examples to the below.

1085AD Manuscript • When we examine our specimen as shown in 1132Limoges|1085, a manuscript created (perhaps) circa 1085AD, we see that it contradicts Mocquereau’s elongations:

If there really was a ‘true’ rhythm, how come these (allegedly) “sloppy” and “capricious” scribes never betray such a thing unwittingly?

1020AD Manuscript • When we examine GradualDenis|1020, which was created (perhaps) circa 1020AD, we see that it contradicts Mocquereau’s elongations:

If there really was a ‘true’ rhythm, how come these (allegedly) “sloppy” and “capricious” scribes never betray such a thing accidentally?

1031AD Manuscript • When we examine 75cambrai|1031, which was created (perhaps) circa 1031AD, we see that it contradicts Mocquereau’s elongations:

If there really was a ‘true’ rhythm, how come these (allegedly) “sloppy” and “capricious” scribes never betray such a thing inadvertently?

965AD Manuscript • When we examine Renaud|965, which was created (perhaps) circa 965AD, we see that it contradicts Mocquereau’s elongations:

If there really was a ‘true’ rhythm, how come these (allegedly) “sloppy” and “capricious” scribes never betray such a thing on accident?

1039AD Manuscript • When we examine 339sanGall|1039, which was created (perhaps) circa 1039AD, we see that it contradicts Mocquereau’s elongations:

1057AD Manuscript • When we examine 857noyon|1057, which was created (perhaps) circa 1057AD, we see that it contradicts Mocquereau’s elongations:

1087AD Manuscript • When we examine 1087cluniacensem|1087, which was created (perhaps) circa 1087AD, we see that it contradicts Mocquereau’s elongations:

1079AD Manuscript • When we examine StMaur|1079, which was created (perhaps) circa 1079AD, we see that it contradicts Mocquereau’s elongations:

1023AD Manuscript • When we examine 123angelica|1023, which was created (perhaps) circa 1023AD, we see that it contradicts Mocquereau’s elongations:

1077AD Manuscript • When we examine 18010corbie|1077, which was created (perhaps) circa 1077AD, we see that it contradicts Mocquereau’s elongations:

1047AD Manuscript • When we examine Albi|1047, which was created (perhaps) circa 1047AD, we see that it contradicts Mocquereau’s elongations:

1040AD Manuscript • When we examine Yrieix|1040, which was created (perhaps) circa 1040AD, we see that it contradicts Mocquereau’s elongations:

1066AD Manuscript • When we examine 1066nimes|1066, which was created (perhaps) circa 1066AD, we see that it contradicts Mocquereau’s elongations:

989AD Manuscript • When we examine Montpellier H. 159, which was created (perhaps) circa 989AD, we see that it contradicts Mocquereau’s elongations:

We recall that Montpellier H. 159 is a very special witness, because it is a “bi-lingual” manuscript, meaning there is absolutely no doubt about each pitch—in spite of the fact that it comes from a (generally speaking) adiastematic period.

    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. Simple 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.

    PDF Download • “Quasi Modo Sunday”
    The Introit for “Quasi Modo Sunday” (12 April 2026) is particularly beautiful. The musical score can be downloaded as a PDF file, and so can the organ accompaniment. The official language of the Catholic Church is Latin (whereas Greek is our mother tongue). Vatican II said Gregorian Chant must be given “first place” under normal circumstances. As a result, some parishes will rightly sing the authentic version. On the other hand, because so many USA dioceses disobey the mandate of Vatican II, some musicians sing plainsong in the vernacular. I have attempted to simultaneously accompany myself on the pipe organ while singing the English version. Although very few take advantage of it, the complete Proprium Missae is posted at the flourishing feasts website.

    ‘German’ Introductions for Hymns
    German organ books have an enchanting habit of including introductions for each and every hymn. For example, consider this snazzy example found in a German hymnal published in 1902. In the Saint Jean de Brébeuf Hymnal, that melody is called “Laudes Mariae” and was married to Omni Die Dic Mariae, with a popular English translation (“Daily, daily, sing to Mary”) by Father Henry Bittleston, an Oratorian priest. Notice they also added a ‘tailpiece’ or ‘playout’ or postlude at the end—a very German thing to do!

Quick Thoughts

    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!

    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.

Random Quote

“Saint Pius X restored to the faithful the two essential means of participation: communion and chant. Unfortunately, owing to prevailing ideas and circumstances, there was a tendency (it still persists) to separate the two, and one consequence of the increase of communions has been the desertion of high Mass; a distinction has grown up between communion Mass (anomalous term) and sung Mass, as if the two were incompatible.”

— Lancelot Capel Sheppard (22 Jan 1955)
