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.

    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for Christmas Midnight Mass (“Ad Missam In Nocte”). If such a thing interests you, feel free to download it as a PDF file. The ENTRANCE CHANT is simple, but quite beautiful. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

    PDF • “Music List” (4th Sunday of Advent)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 21 December 2025, which is the 4th Sunday of Advent (Year A). If such a thing interests you, feel free to download it as a PDF file. The ENTRANCE CHANT is the famous “Roráte Coeli” and the fauxbourdon setting of the COMMUNION is exquisite. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

Quick Thoughts

    What does this mean? “Pre-Urbanite”
    One of the things informed critics have frequently praised vis-à-vis the Saint Jean de Brébeuf Hymnal has to do with its careful treatment of the ancient hymns vs. the “Urbanite” hymns. This topic I had believed to be fairly well understood—but I was wrong. The reason I thought people knew about it is simple; in the EDITIO VATICANA 1908 Graduale Romanum (as well as the 1913 Liber Antiphonarius) both versions are provided, right next to each other. You can see what I mean by examining this PDF file from the Roman Gradual of 1908. Most people still don’t understand that the Urbanite versions were never adopted by any priests or monks who sang the Divine Office each day. Switching would have required a massive amount of effort and money, because all the books would need to be changed.

    PDF Download • “Santo Santo Santo”
    Those searching for a dignified, brief, simple, bright setting of SANCTUS in Spanish (“Santo Santo Santo”) are invited to download this Setting in honor of Saint John Brébeuf (organist & vocalist). I wonder if there would be any interest in me recording a rehearsal video for this piece.

Random Quote

According to the Instruction “Musicam sacram” of 5 March 1967, Article 34 §1, the polyphonic “Ordinarium Missae” can in the future still be sung suetis normis, “according to the customary norms,” i.e. by the choir. In fact, this form of the high Mass is placed in high relief compared to the other forms, among which the congregationally sung Gregorian chant Mass deserves our special attention.

— Monsignor Overath (President, “Consociatio Internationalis Musicæ Sacræ” founded by Pope Saint Paul VI
