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 • “Disputed Questions” (16 Nov 2022)

Dr. Charles Weaver · November 16, 2022

IN my previous post, I argued against two frequent assertions of Jeff Ostrowski. He has responded thus:

It may seem insignificant, but I would like to underscore that I don’t consider these claims as mine. For instance, the letter from the Prefect for the Congregation of Sacred Rites dated 18 February 1910 speaks (explicitly) on behalf of “the mind of the Holy Father and of the Sacred Congregation of Rites.” That letter specifically says “the rhythmical form of the melodies […] is inseparable from the edition itself.”

I will try to clarify exactly what two claims I am disputing. You can read what I wrote in context, but here the two claims are, in the form of questions:

  1. Does the rhythmic interpretation described in the Vatican Edition preface remain the “official rhythm of the Catholic Church?”
  2. Are the Solesmes rhythmic signs “illicit?”

In the first question, the key word is remain. Ostrowski frequently uses phrases such as “the rhythm of the official edition is still technically mandated by the church.” If this is so, is there a current document that states this mandate, which remains in place? Is there a current member of the Roman curia who would agree with this stance? Does Ostrowski’s position reflect the mind of the current Holy Father? The latest piece of evidence he has given so far is from 1958, and even that is open to different interpretations by reasonable people. A lot has changed in the realm of sacred music since then.

As to the second question, I will also need to see some further evidence. The fact of history remains that as long as there has been a typical edition of the Roman Gradual, there has also been a typical edition of the Roman Gradual with added rhythmic signs. These have been permitted, tolerated, or allowed with varying degrees of coolness or warmth by the Roman authorities since the beginning, but the key point is that they have been allowed. There was indeed a lot of polemic directed against the signs in 1906 and for perhaps a decade after. But nowhere (after the change in design of the Solesmes signs) does a member of the hierarchy definitively say “The Solesmes signs are illicit.”

I insist on this point because it seems impossible to me to have a discussion of paleography or performance practice if we cannot agree on what the Catholic Church allows with regard to singing Gregorian chant. At least one reader has been convinced that “it seems we have all been disobedient.” I say, to the contrary, that anyone who sings Gregorian Chant liturgically with the intention of serving the most beautiful and artful liturgical practice has absolutely not been disobedient but is working for the good of the Church. Both Bruno de Labriolle and the nuns of Jouques are doing great things for the cause of sacred music. If either of these are violating a mandate of the Church by the way they sing, I will have to see better evidence of it than what has been offered so far.

    Dom Pothier • Photo from 1904
    Dom Paul Cagin, in a 1904 publication (L’oeuvre de Solesmes dans la restauration du chant grégorien) made sure to include a beautiful image of Dom Pothier, the legendary abbot of St-Wandrille. Also shown is a very young Dom André Mocquereau. Auguste Pécoul—considered the spiritual “son” of Abbat Prosper Guéranger of Solesmes—wrote as follows on 24 June 1901: “To forestall any confusion, let us remember that there is just one Gregorian notation—that restored, according to the ancient manuscripts, by the eminent Abbot of Saint-Wandrille, Dom Pothier.” ✠

    PDF • “3-Voice Motet” (Father De Laet)
    I believe 99% of our readers will recognize this hymn tune. Perhaps Father Edgard De Laet should have called it a ‘hymn’ instead of a ‘motet for three voices’—but he’s technically correct, since MOTET is defined as: “a short piece of sacred choral music, typically polyphonic and unaccompanied.” The even verses are for three voices, as you will see if you download the PDF score at #20245. The odd verses may be song a cappella SATB or unison with organ.

    PDF Download • “Hymn for 2 Voices”
    Readers who click on this video will see that it starts with verses of the “Pange Lingua” hymn by Saint Thomas Aquinas (d. 1274) arranged for two voices. However, there’s a polyphonic refrain (“Tantum Ergo”) for three voices, taken from Kevin Allen’s Motecta Trium Vocum. If your choir is very small, this piece is for you! You can download the PDF score free of charge—and you can also utilize the rehearsal videos for each individual voice—by navigating yourself to #20323.

Quick Thoughts

    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

“Who dreamed on that day that within a few years, far less than a decade, the Latin past of the Church would be all but expunged, that it would be reduced to a memory fading in the middle distance? The thought of it would have horrified us, but it seemed so far beyond the realm of the possible as to be ridiculous. So we laughed it off.”

— Most Rev’d Robert J. Dwyer, Archbishop of Portland (d. 1976)
