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.

    Spectacular Communion Setting!
    The FAUXBOURDON setting of the Communion for the Baptism of the Lord (which will occur this coming Sunday) strikes me as quite spectacular. The verses—composed by the fifth century Christian poet, Coelius Sedulius—come from a long alphabetical acrostic and are deservedly famous. The feast of the LORD’S BAPTISM was traditionally the octave day of Epiphany, but in the 1962 kalendar it was made ‘more explicit’ or emphasized. The 1970 MISSALE ROMANUM elevated this feast even further.

    PDF • “Music List” (Sunday, 11 January)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for Feast of the Baptism of the Lord (SUNDAY, 11 January 2025). If such a thing interests you, feel free to download it as a PDF file. The FAUXBOURDON verses for the Communion Antiphon—to say nothing of the antiphon itself—are breathtaking. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the monumental feasts website alongside the official texts in Latin.

    Epiphany Hymn • “New 2-Voice Arrangement”
    The Von Trapp Family Singers loved a melody that was featured heavily (perhaps even “too heavily”) in the Brébeuf Hymnal. It goes by many names, including ALTONA, VOM HIMMEL HOCH, and ERFURT. If you only have one man and one woman singing, you will want to download this arrangement for two voices. It really is a marvelous tune—and it’s especially fitting during the season of Christmas and Epiphany.

    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.

    PDF Download • “In Paradisum” in English
    We always sing the IN PARADISUM in Latin, as printed on this PDF score. I have an appallingly bad memory (meaning I’d be a horrible witness in court). In any event, it’s been brought to my attention that 15 years ago I created this organ accompaniment for the famous and beautiful ‘IN PARADISUM’ Gregorian chant sung in English according to ‘MR3’ (Roman Missal, Third Edition). If anyone desires such a thing, feel free to download and print. Looking back, I wish I’d brought the TENOR and BASS voices into a unison (on B-Natural) for the word “welcome” on the second line.

Random Quote

“I vividly remember going to church with him in Bournemouth. He was a devout Roman Catholic and it was soon after the Church had changed the liturgy (from Latin to English). My grandfather obviously didn’t agree with this and made all the responses very loudly in Latin while the rest of the congregation answered in English. I found the whole experience quite excruciating, but my grandfather was oblivious. He simply had to do what he believed to be right.”

— Simon Tolkien (2003)
