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.”

Report • “Musical Shape of the Liturgy Conference”

Dr. Charles Weaver · November 9, 2023

HIS WEEK the Catholic Institute of Sacred Music, a new initiative headed by Dr. Jennifer Donelson-Nowicka, held a conference in honor of the life and work of the extraordinary William Mahrt. The conference took place at St. Patrick’s Seminary in Menlo Park, CA. This is the seminary of the Archdiocese of San Francisco, where Dr. Donelson-Nowicka is a professor. As is usual with academic conferences, the schedule was packed with papers. Less usual, at least for music-related fields, was that many of the papers were presented in hour-long blocks, with 40–45 minutes for the paper, followed by 15–20 minutes of question time. This allowed for an amount of depth and detail that was unusual. Most time blocks had three papers going simultaneously, which left the participants with some hard choices. There were some more papers I wish I could have seen.

Also unusually for music conferences (at least in my experience), solemn Catholic liturgies were held several times a day between the paper sessions: Lauds, Vespers, Solemn Mass. The music was provided by Mahrt’s own St. Ann Choir, with conducting by Mahrt, Donelson-Nowicka, and David Hughes, my long-time former director in Norwalk. The singing was quite good. I particularly enjoyed sitting behind Fr. Bachmann, choirmaster at Clear Creek Abbey, during the office. He sounds like a monk of the Solesmes congregation, because that’s exactly what he is.

I had to arrive late and leave early because of schedule constraints, but I was able to attend three plenary events: keynote papers by Dr. Joseph Dyer on some Old Roman chant and Sr. Maria Kiely (of Solesmes!) on Latin as a sacred language and some of its rhetorical qualities in liturgical use. The third event was the banquet, with some very moving tributes to Mahrt and his influence.

As you might expect, I followed a chant-oriented itinerary through the conference papers. Especially noteworthy were two papers touching on the rhythm of Gregorian chant. Br. John Glasenapp (of Meinrad Archabbey) presented some really interesting research on the Cistercian reform of the chant repertoire in the late middle ages. He used this as a way to raise questions about some patterns of narrative (i.e., decay-restoration or decadence-reform) that recur throughout the history of the repertoire. Perhaps closer to my own research topics was a really interesting paper by Steven Ottományi on language and rhythm in chant. He was mainly looking at the Pothier-Mocquereau dispute, trying to come up with new and better ways to describe points of agreement and difference. His boldest claim is that the difference between their ways of accentuating chant may relate to regional variations in the way French is spoken in their birthplaces. Obviously such a cause, if it is true, is not entirely demonstrable and also would be in some quite deep stratum of their mental furniture, but it was an interesting point.

I also gave a paper this morning, on the connection between Mocquereau and various nineteenth- and twentieth-century theorists. It was based on the research in the fourth chapter of my recent dissertation. In some ways, I think my points were quite complementary with those of Glasenapp and Ottományi. Say of Mocquereau what you will as a chant practitioner, but I’m heartened to see the interest in my research looking at him as a theorist of music. The rhythmic signs, which have proven so controversial in chant circles, are really a very small part of Mocquereau’s theory.

From my point of view, the conference was quite successful. There was a lot of interesting scholarship to take in, and it was inspiring to see the fruits of Dr. Mahrt’s long career as both a practicing musician and a scholar, and a generous teacher. I hope to see many more such conferences in the future!

    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 • “Cantus Mariales” (192 pages)
    Andrea Leal has posted an absolutely pristine scan of CANTUS MARIALES (192 pages) which can be downloaded as a PDF file. To access this treasure, navigate to the frabjous article Andrea posted Monday. The file is being offered completely free of charge. The beginning pages of the book have something not to be missed: viz. a letter from Pope Saint Pius X to Dom Pothier, in which the pope calls Abbat Pothier “a man versed above all others in the science of liturgy, and to whom the cause of Gregorian chant is greatly indebted.”

    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.

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 priest coming nearer to the faithful; communicating with them; praying and singing with them and therefore standing at the pulpit; saying the COLLECT, the EPISTLE, and the GOSPEL in their language; the priest singing in the divine traditional melodies—the Kyrie, the Gloria, the Credo—with the faithful: these are so many good reforms that give back to that part of the Mass its true finality.”

— Archbishop Marcel Lefebvre (1965) praising vernacular readings at Mass
