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.”

Are We Done? • “Gregorian Chant Rhythm Wars”

Jeff Ostrowski · October 9, 2023

OR MORE than 13 years, our blog authors have been examining, discussing, and arguing about the rhythm of Gregorian Chant. In terms of the series we have called Gregorian Rhythm Wars, it’s been decided to bring that particular series to a close. As they say: All good things must come to an end. We’re grateful to all who contributed to that series. The various articles will remain online for anyone wishing to consult them at a later date. You’re free to consult our series, but you’re not free to insult our series! 😁

Are We Finished? • Needless to say, our blog authors will continue to discuss the question of plainsong rhythm. Something that becomes more pressing each day—at least as far as I’m concerned—is the need for honesty. Had everyone been honest, I truly believe the history of plainsong might have been different. For example, I wish Dom Mocquereau had publicly admitted something like the following:

“I really like four particular manuscripts. As far as I’m concerned, these are the only ones that matter. While it’s true that thousands of other Gregorian manuscripts are also incredibly ancient, powerful, and important, as far as I’m concerned those don’t exist. That is to say, they don’t count for anything. They can be completely ignored. I have chosen my four, and these are what I go by.”

I suspect not all of my colleagues will agree with my statements; and that’s precisely why our conversations will continue!

Looking Back • Looking back upon the Gregorian Rhythm Wars, the main point I personally tried to “put forward” or “emphasize” or “insist upon” was that making broad statements about plainsong rhythm is insufficient, especially when such statements are contradicted by manuscript evidence. Rather, we must point to evidence which supports our theories. Owing to the enormous amount of manuscripts uploaded to the internet on a weekly basis, many theories popular in the 1950s must be abandoned. Indeed, members of our organization are attempting to make it simple for anyone to instantly access the evidence (so everyone can see it with their own eyes). We began with fifty seven manuscripts and plan on adding hundreds more in the future.

    2-Voice Arrangement for Lent
    Those seeking a two-voice arrangement for LENT and PASSIONTIDE should click here and scroll down. It’s based on number 775 in the Brébeuf Hymnal, with an enchanting melody written by Kevin Allen (the legendary American composer of sacred music). That text—“Pendens In Crucis Cornibus”—is often used for the Feast of our Lady of Sorrows. That link is important because, in addition to the musical score, it provides free rehearsal videos for each individual voice: something volunteer choirs appreciate!

    “Sanctus VIII” • Organ Accompaniment
    A few days ago, I composed this organ harmonization for SANCTUS VIII. This Mass is traditionally called Missa de ángelis or “Mass of the angels.” In French, it is Messe de Anges. You can evaluate my attempt to simultaneously accompany myself on the pipe organ (click here) while singing the melody. My parish is currently singing this setting.

    Music List • (5th Sund. Ordinary Time)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for this coming Sunday, 8 February 2026, which is the 5th Sunday in Ordinary Time (Year A). If such a thing interests you, feel free to download it as a PDF file. You will probably notice it isn’t as ‘complete’ or ‘spiffy’ as usual, owing to some difficulties which took place this week.

    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 effectiveness of liturgy does not lie in experimenting with rites and altering them over and over, nor in a continuous reductionism, but solely in entering more deeply into the word of God and the mystery being celebrated. It is the presence of these two that authenticates the Church’s rites, not what some priest decides, indulging his own preferences.
