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 · February 12, 2026

ORTY NINE YEARS ago—in 1977 to be exact—Monsignor Francis P. Schmitt famously included several paragraphs in his book (Church Music Transgressed) deriding TLM Catholics of the 1970s. For example, he rebuked those “whose pamphleteers are forever talking about the beauty of Gregorian chant, by which, it turns out, they mean Mass VIII, a piece neither traditional nor all that beautiful.” Mass VIII is often called “Mass of the Angels” (Missa de ángelis)—and CREDO III was often included in it. For instance, cf. the collection by Jean-Baptiste Labelle, a Canadian organist who studied with Thalberg. As a matter of fact, Monsignor Schmitt was incorrect; several movements from Mass VIII are extremely ancient. [More on that momentarily.]

Jeff’s Attempt • Since our congregation is currently singing SANCTUS VIII, I composed the following harmonization which adheres to the modal theories of the LEMMENSINSTITUUT (broadly speaking), with one exception:

*  PDF Download • SANCTUS VIII —Jeff’s harmonization
—Mass VIII is sometimes called “Mass of the Angels” (Missa de Angelis).

Here’s the direct URL link.

My edition follows the official rhythm. In other words, it uses the rhythm that was intended by those who—at the behest of Pope Saint Pius X—created the EDITIO VATICANA. Dom André Mocquereau had a different theory of rhythm. Specifically, Mocquereau believed the ‘stress’ or ‘accent’ or ‘stroke’ of Gregorian Chant should go on the final syllable, just as it does in the French language. For example, consider the way Dom Mocquereau marked GLORIA XV (Dominátor Deus) in his 1904 LIBER USUALIS:

Therefore, we won’t be surprised to observe that Dom Mocquereau modified the Editio Vaticana by adding all kinds of elongations on the final syllables of Latin words. What is slightly surprising, however, is the fact that Mocquereau’s arch-nemesis, Dom Lucien David, adopted these elongations in his 1932 edition. That illustrates how popular the Mocquereau editions had become in the 1930s:

It will be remembered that the official edition (“EDITIO VATICANA”) gives very little indication when it comes to syllabic plainsong. We see that by examining the Nova Organi Harmonia published by the LEMMENSINSTITUUT, which was punctilious in its adherence to the official rhythm:

Dr. Peter Wagner (Commissionis Pontificiæ Gregorianæ Membrum) also follows the official rhythm:

This is perfectly consistent with the original 1883 edition by Abbat Joseph Pothier:

On the other hand, it isn’t absolutely forbidden to add some elongations for syllabic chants; far from it! Abbat Pothier and his Vatican Commission on Gregorian Chant never intended to ‘micromanage’ or ‘control’ with excessive precision how every choir would approach syllabic sections. For instance, notice how Max Springer of Beuron added a slight elongation in his 1914 edition:

Monsignor Franz Nekes (called by some: “The German Palestrina”) did the same thing in his 1906 harmonization:

Indeed, other “pure” Vaticana editions follow suit. The famous Schwann edition of 1906 does. So does the edition by the Alsatian organist and composer, Father Xaver Mathias, who founded the Saint Leo Institute for Sacred Music at Strasburg Cathedral in 1913. This was also the approach I adopted. In other words, I adopted a type of via media which avoids the excessive “stop and go” approach by Dom Mocquereau:

I can see no justification for all those added pauses. (For the record, Mocquereau kept them in the subsequent editions.)

Concluding Thoughts • At the beginning of this article, I said parts of the Missa de ángelis are quite ancient. He who searches for “O Quam Suávis Est” will discover hundreds of the most gorgeous ancient manuscripts:

SANCTUS VIII is a contrafact of the “O Quam Suávis Est” melody.

Here’s yet another example:

    Pipe Organ “Answers” in Plainsong?
    In 2003, I copied a book by Félix Bélédin (d. 1895), who was titular organist—from 1841 to 1874—at the Cathedral of Saint John the Baptist in Lyon (France). In 2008, we scanned and uploaded the book to the Lalande Online Library. Nobody knows for sure when the book was published; some believe it first appeared in the 1840s. In any event, one who examines this excerpt, showing GLORIA IX might wonder why it says the organ answers in plainsong. However, the front of the book explains, telling the organist explicitly when to “respond in plainchant.” This is something called organ alternatim. Believe it or not, the pipe organ would take turns with the choir, playing certain texts instrumentally instead of having them sung. I’m not very well-versed in this—pardon the pun—but if memory serves, ORGAN ALTERNATIM was frowned upon by the time of Pope Saint Pius X. Nevertheless, French organists kept doing it, even after it was explicitly condemned as an abuse.

    Music List • (5th Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 5th Sunday of Lent (22 March 2026). If such a thing interests you, feel free to download it as a PDF file. Traditionally, this Sunday was called ‘Passion’ Sunday. Starting in 1956, certain church leaders attempted rename both ‘Passion’ Sunday and ‘Palm’ Sunday—but it didn’t work. For example, Monsignor Frederick McManus tried to get people to call PALM SUNDAY “Second Passion Sunday”—but the faithful rejected that. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

    Readers have expressed interest in seeing the ORDER OF MUSIC I created for Holy Thursday, which is 2 April 2026. If such a thing interests you, feel free to download it as a PDF file. I’m not sure I’ve ever heard a more piercingly beautiful INTROIT, and I have come to absolutely love the SATB version of ‘Ubi cáritas’ we are singing (joined by our burgeoning children’s choir). I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

Quick Thoughts

    “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.

    PDF Download • “Holy, Holy, Holy”
    For vigil Masses on Saturday (a.k.a. “anticipated” Masses) we use this simpler setting of the “Holy, Holy, Holy” by Monsignor Jules Vyverman (d. 1989), a Belgian priest, organist, composer, and music educator who ultimately succeeded another ‘Jules’ (CANON JULES VAN NUFFEL) as director of the Lemmensinstituut in Belgium. Although I could be wrong, my understanding is that the LEMMENSINSTITUUT eventually merged with “Catholic University of Leuven” (originally founded in 1425). That’s the university Fulton J. Sheen attended.

Random Quote

“I prefer to say nothing, or very little, about the new calendar, the handiwork of a trio of maniacs who suppressed—with no good reason—Septuagesima and the Octave of Pentecost and who scattered three quarters of the Saints higgledy-piddledy, all based on notions of their own devising!”

— ‘Fr. Bouyer, Consilium member appointed by Pope Paul VI’
