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!

    “Reminder” — Month of April (2026)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. It couldn’t be easier to subscribe!

    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. Simply 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.

Quick Thoughts

    PDF Download • “Anima Christi”
    I received a request for an organ accompaniment I created way back in 2007 for the “Anima Christi” Gregorian Chant. You can download this PDF file which has the score in plainsong followed by a keyboard accompaniment. Many melodies have been paired with “Anima Christi” over the centuries, but this is—perhaps—the most common one.

    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!

Random Quote

“…I started down the road of the liturgy, and this became a continuous process of growth into a grand reality transcending all particular individuals and generations, a reality that became an occasion for me of ever-new amazement and discovery. The incredible reality of the Catholic liturgy has accompanied me through all phases of life, and so I shall have to speak of it time and again.”

— Joseph Cardinal Ratzinger
