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.”

Gregorian Chant Introit • (Sung According to the Official Rhythm of the Catholic Church)

Jeff Ostrowski · September 19, 2023

ECAUSE OF VARIOUS obligations which take up my time and energy, I have not always been able to respond to questions from Patrick Williams in the Gregorian Rhythm Wars series. However, I believe readers who examine my articles will notice I made a “good faith effort” to handle as many questions as possible (although it sometimes takes me a while to find the requisite time). Since I have a few moments, let me try to respond to an issue Patrick raised in his 16 September 2023 installment. Specifically, Patrick gave examples where I added arrows—and similar markings—to the official edition, asking:

In all seriousness, how are all of Jeff’s markings and alterations fine if Mocquereau’s (and mine) are supposedly absolutely forbidden? It is difficult to fathom how adding a dotted line straight through all four lines of the staff is permissible but writing a dot after a note is out of the question.

Patrick, I would direct your attention to DE MUSICA SACRA (“Instruction on Sacred Music”) issued under Pope Pius XII in 1958. In particular, notice the following section:

The “force and meaning” incontestably refers to the rhythm—not the pitch—when we consider the rest of the paragraph.

This Coming Sunday • In the Extraordinary Form, this coming Sunday is the 17th Sunday after Pentecost. I have recorded a rehearsal video for the INTROIT (“Justus es Dómine”), sung according to the official rhythm:

Here’s the direct URL link.

Rational Beings • Almighty God created us as rational beings. We can be certain that an arrow pointing to an “MMV” (melismatic mora vocis) does not modify or contradict the official rhythm. Over the last 10 years, I have provided hundreds of examples—and I could easily cite thousands more—where Dom Mocquereau’s editions contradict the official rhythm by adding elongations where they don’t belong or by omitting elongations which are supposed to be there. By doing such things, Dom Mocquereau does not preserve “the force and meaning of the notes found in the Vatican books of liturgical chant.” Dom Lucien David, protégé of the monk appointed by Pope Saint Pius X as president of the Vatican Commission on Gregorian Chant, published a fabulous edition in 1932 virtually identical to the edition I’m in the process of creating. I never knew about those books by Dom Lucien David until Dr. Charles Weaver told me. (Had I known about them back in 1997, my life would have been quite different—but Dr. Weaver made the decision to wait 26 years to inform me.)

A Single Breath Mark! • Perhaps you noticed that in my score (above) I indicated a place where a quick breath might be taken—in spite of the fact that the official edition says nothing about that. As I have tried to explain over the last several decades, ABBAT POTHIER left freedom to each individual choirmaster when it comes to minor matters. To explain things another way, it would be irrational for someone to say: “Jeff added a possible breath mark were none was indicated in the official edition. By doing so, he has endorsed the 40,000 modifications by Dom Mocquereau.” As rational beings, we are capable of making distinctions when it comes to minor issues Vs. major issues. Moreover, this is not something I invented. Pothier’s “freedom” is illustrated by those who produced editions of the EDITIO VATICANA, such as Professor Amédée Gastoué, Dr. Peter Wagner, Father Franz Mathias, Maxwell Springer, Marcel Dupré, Dom Lucien David, Joseph Gogniat, Monsignor Franz Nekes, the LEMMENSINSTITUUT, and so forth.

Patrick’s Keen Eye • I must admit that Patrick has a keen eye. He spotted an instance where I eliminated some liquescent notes. I did that because some of my singers struggle with liquescent notes—and I made the judgment call that this was not a change of deep significance, especially considering the current crisis of the church. So there’s that “rational” business again! I decided it was not an issue of great significance—and others are free to criticize me for this.1

Excessive Force • The musical reforms of Pope Saint Pius X are not above criticism. For instance, following his decrees, some believed only plainchant was allowed. That meant many of the beautiful traditions of parish Vespers were eliminated—and I would suggest this was a travesty. One thing in particular happened in those days: something I believe was reprehensible. The Germans had simple little melodies they used for the plainchant between the Epistle and Gospel. They had used those melodies for many years, and loved them. Pressure was brought to bear on Monsignor Haberl, who pleaded in for their continued use—but his pleadings fell upon deaf ears. Essentially, Haberl was told that the only permissible “simplified melodies” were those constructed according to the psalmody patterns in the EDITIO VATICANA. As far as I’m concerned, that ruling was absurd. Singing simplified versions of those chants—even though they didn’t match the EDITIO VATICANA simplified versions—should have been allowed to continue. This is doubly true when we consider all the different forms of music fully allowed for those same chants. Even modern polyphony was allowed!

1 For the record, Joseph Gogniat criticized Abbat Pothier over his inconsistency vis-à-vis liquescent notes. As a matter of fact, Abbat Pothier simply followed the ancient manuscripts, which are themselves inconsistent in that regard.

    Music List • (2nd Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 2nd Sunday of Lent (1 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has magnificent propers. Its somber INTROIT is particularly striking—using a haunting tonality—but the COMMUNION with its fauxbourdon verses is also quite remarkable. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

    Which Mass?
    In 1905, when the Vatican Commission on Gregorian Chant began publishing the EDITIO VATICANA—still the Church’s official edition— they assigned different Masses to different types of feasts. However, they were careful to add a note (which began with the words “Qualislibet cantus hujus Ordinarii…”) making clear “chants from one Mass may be used together with those from others.” Sadly, I sometimes worked for TLM priests who weren’t fluent in Latin. As a result, they stubbornly insisted Mass settings were ‘assigned’ to different feasts and seasons (which is false). To understand the great variety, one should examine the 1904 KYRIALE of Dr. Peter Wagner. One should also look through Dom Mocquereau’s Liber Usualis (1904), in which the Masses are all mixed up. For instance, Gloria II in his book ended up being moved to the ‘ad libitum’ appendix in the EDITIO VATICANA.

Quick Thoughts

    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.”

    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.

Random Quote

“The council did not say Latin should be abolished. It said Latin should be used. […] While at Ecclesia Dei, I once received a letter from a chancery office in the United States, asking me if I didn’t know that the council had abolished Latin!”

— Cardinal Mayer, Prefect (1985–1988) of the Vatican’s Congregation for Divine Worship
