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.”

Christmas • “Approached By A Famous Musicologist”

Jeff Ostrowski · December 30, 2023

ISCONCERTING. Dr. Katharine Ellis—professor of musicology at Cambridge University in England—uses the word “disconcerting” to describe the argument I’ve been putting forth in terms of Dom Mocquereau’s illicit befouling of the Church’s official edition of Gregorian Chant. The way I’ve described matters is: Dom Mocquereau takes into account the complete plainsong repertoire when it comes to pitches, but only a handful of manuscripts when it comes to rhythm. I have described this minuscule portion of manuscripts—for which he has a predilection—as “MOC’S FANTASTIC FOUR.” In other words, I’ve pointed out how Dom Mocquereau, looking over the entire collection of ancient Gregorian manuscripts, unabashedly declared almost every single one of them to be ‘garbage’ from the standpoint of rhythm (although he valued those same manuscripts highly vis-à-vis the pitches).

Snazzy Words • Describing this phenomenon, Dr. Katharine Ellis uses fancier words on page 112 of her book (The Politics of Plainchant in fin-de-siècle France, 2013). If you’re somebody who likes grandiloquence, you will prefer her description to mine. But the argument she’s putting forth is very similar to mine:

The scientific drive for statistical proof that characterizes Mocquereau’s work on pitch contour is replaced, in his work on rhythm and interpretation, by extrapolation from a minute body of comparative evidence and the making of creative leaps in its analysis. Dom Mocquereau provides no equivalent, for rhythm, of the huge body of raw data used in the Paléographie musicale to demonstrate Gregorian melodic unity via Justus ut palma. He cannot. Instead he does the opposite: he elaborates an aesthetically based theory of interpretation which he presents—distilled via carefully selected examples—as both general and normative.

I warned you that Dr. Ellis uses snazzier words than I do!

Numerous Reasons • Some have claimed that I embrace the official edition “because it comes from authority.” I suppose that’s one reason, but there are many! For instance, it just makes sense to sing an edition the way it was intended to be sung by those who created it. Moreover, I believe the illicit elongations by Dom Mocquereau destroy the melodic line (often fatally) and tend to make plainsong fussy and plodding. Furthermore, having examined the ancient manuscripts for more than twenty years, I haven’t been able to find any evidence supporting the rhythmic claims of Dom Mocquereau—or, for that matter, his disciple, Dom Eugène Cardine.1

Does It Matter? • Does any of this matter? Readers must decide for themselves. I invite you to consider the first antiphon for CHRISTMAS VESPERS:

—Dom Mocquereau Vs. the Official Edition.

Looking at that chart, is there anything more to be said?

Famous Musicologist • A famous plainchant scholar approached me after one of our Christmas Masses last week. (This person is a university professor I’ve been following since the 1990s.) Coming forward, he shook my hand and said: “I want to thank you for supporting the official edition.”

1 I remain open to being convinced, if any readers are willing to point out such evidence.

    Season’s End Repertoire
    Looking at the REPERTOIRE SHEET until the end of the choral season, I see that I’ve fallen behind schedule. (The last three months have been extraordinarily busy.) As you know, I have been providing organ harmonies for all the ENTRANCE CHANTS—as well as rehearsal videos—and you can see I’m behind where I planned to be. Now I must make up lost ground. However, the choir picks up the ENTRANCE CHANT with ease, so I’m sure it will all work out. My ‘unofficial’ harmonizations are being posted each week at the flourishing feasts website.

    PDF Download • “Funeral Procession”
    From a mediæval Book of Hours, I was sent this glorious depiction of a Roman Catholic funeral procession by Simon Bening (d. 1561). The image resolution is extremely high. I’m not sure I know of a more beautiful illustration of a mediæval church. And I love how the servers are wearing red and pink cassocks!

    Simplified Accomp. • Schubert’s “Ave Maria.”
    Sometimes the organist must simultaneously serve as the CANTOR. (Those who work in the field of church music know exactly what I’m talking about.) One of our contributors composed this simplified keyboard accompaniment for Franz Schubert’s “Ave Maria,” a piece which is frequently requested for Catholic funerals and weddings. In terms of the discussion about whether that piece is too theatrical (‘operatic’) for use in Church, I will leave that discussion to others. All I know is, many church musicians out there will appreciate this simplified version.

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!
