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.”

In Praise of Adaptability

Dr. Charles Weaver · July 8, 2023

THERE IS A REHEARSAL TECHNIQUE we often use as conductors, especially in pedagogical settings, to encourage a particular interpretation that we want from our ensembles. We demonstrate two ways of performing a passage. First we show what we don’t want, such as a stiff and wooden performance lacking in energy and dynamic contrast. Then we show the beautifully shaped and crafted performance we want. The implication is that the first way is what the ensemble did on the previous time through the passage, and if only they would watch and follow us, we can get the group to do the thing we want.

I’ve been on both the giving and the receiving end of this technique, and I think it’s mostly a pretty lousy trick. If overused, it can be pretty demoralizing for the performers, especially in a professional setting. When we give the exaggerated, negative portrayal of the performance we don’t want, it often comes across as an ill-mannered caricature of our ensemble members. So even though it often gets results, it should probably not be overused.

Something similar can happen when it comes to debates over the interpretation of Gregorian chant. It’s very easy to paint the people with whom we disagree with the broad brush of “lack of musicality.” You can see this all through the last century and a half in countless articles and books from pretty much every point of view. I think we ought to move away from this approach, because, by adopting it, we limit our own artistic range as singers and conductors.

As an alternative, I want to propose that anyone interested in these questions ought to learn to display some adaptability. An excellent example of this is Patrick Williams’s recent video introducing mensuralism. Here Patrick’s method is not to make his opponents seem unreasonable but to present several contrasting ways of singing the same melody. This is a good way of going about it! I don’t agree with every performance choice Patrick makes in this video, but I commend him for presenting so many different ways convincingly. The principle of charity dictates that we present our opponents’ arguments in the best possible light; this is precisely, for instance, how St. Thomas approaches topics in his Summa.

I’ve been thinking about this question a lot for numerous reasons. First, a dispassionate description of multiple interpretive approaches to plainchant was a major part of my dissertation, which I recently defended successfully. This dissertation will be publicly available soon, and I hope this portion of it can become the basis for a future book, a sort of field manual for various interpretive styles. Second, I was deeply moved by a recent podcast episode, from Square Notes, about the life and work of Mary Berry. In particular, I learned that this great scholar and promoter of chant was perfectly happy to follow the Solesmes/Ward method in some contexts and Cardine’s semiology in others, in addition to her early work on Renaissance performance practice. Third, I just wrapped up teaching a course on Gregorian rhythm at the newly established Catholic Institute of Sacred Music in Menlo Park, CA. Each day I presented a different approach to rhythm: Haberl/Medicean; Pothier/Vatican; Mocquereau/Solesmes; Cardine/Guilmard; and Mensuralism/Vollaerts. I did my best to “steel-man” the arguments for each of these. At the end I had students present the same melody using two different performance methods of their choice and discuss the arguments for each. I was very inspired by what they came up with.

Now, a note of caution is in order here. Isn’t there a risk of becoming a jack of all trades and a master of none? Perhaps. And within a religious community or even within a parish choir, it is probably best to limit the interpretive range that we use for singing and instruction, at the risk of confusing singers or damaging the cohesiveness of the ensemble. Still, as singers and conductors of chant who seriously want to understand the issues, I believe we can only improve our own musical skills if we show a bit of adaptability. I am convinced that my chironomy and my Mocquereau-type singing is better for having spent a long time taking Cardine, Ostrowski, Williams, Vollaerts, et. al. seriously. If I were a committed practitioner of mensuralism, I imagine some engagement with, say, Mocquereau’s ideas about the phrase construction and form would be useful, even if it would mean engaging in an interpretation of the historical evidence and the tradition that I disagreed with. If there are any readers on here who think that everything depends on a precise, Mocquereau-inspired ictus placement and chironomy, then try a course in semiology! If there is anyone who is offended by mensuralism in chant, try a course in mensuralism! And so on and so forth. You don’t have to bring what you learn into your own schola, but it may well help you get some perspective on the decisions you do make as a chanter or conductor.

This kind of comparative approach was also the basis for some of the chant recordings we made on the last day of our recent Sacred Music Symposium. I am very grateful for the participants and colleagues who have facilitated such charitable and, I believe, profitable discussions. My hope for all the people who took part is that we made their practice of chant just a little better. Sursum corda!

    “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! Just scroll to the bottom of any blog article and enter your email address.

    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

It is known that the “mora vocis” is part of the compulsory rules of recital of the “Vaticana” and is indicated in the Editio typica and its reprints by a somewhat larger spacing of the neume (one space-line) within one group of neuma.
