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.”

Mocquereau Rhythmic Signs

Jeff Ostrowski · November 4, 2023

PDF • Draft Booklet “Couture Chant” (255 Pages)

This is very much a “work in progress”…

Dr. Charles Weaver · October 5, 2023

PDF Dissertation • “Dom Mocquereau and Music Theory” (282 Pages)

My thesis on how Dom Mocquereau relates to other theories of musical rhythm is now available for download.

Jeff Ostrowski · May 24, 2023

Analysis • “Archaic and Quack Ideas on Chant”

“Gentlemen: Nobody is going to follow the archaic and quack ideas on Chant you are trying to propagate.” Mr. John Sandar

Jeff Ostrowski · April 27, 2023

PDF Download • “English Hymns for Three Voices” (SSA), edited by Dr. Theodore Marier—182 pages

My choir will definitely be using these settings. They’re something many have begged for!

“Solesmes Ictus” • Can It Be Justified? (Examples)

“If you begin by telling a man that in a word like 𝐷𝑒𝑢𝑠 the first syllable corresponds to the weak beat, the second to the strong beat of a modern bar, the only thing accomplished will be to bewilder him thoroughly.” —Father Bewerunge

Dr. Charles Weaver · January 26, 2023

What is the Tonic Accent?

We should define our terms. What makes a syllable accented, and what makes an accent a tonic accent?

PDF Download • 1909 “Modern Notation” Gradual (Extremely Rare) — 712 Pages

The truth is stranger than fiction.

Video • “Counting Gregorian Chant” … according to Dom Mocquereau’s Method

The example chosen is the strenuous offertory (“Jubiláte Déo”) for the 2nd Sunday after Epiphany.

Jeff Ostrowski · January 5, 2023

“Solesmes Method” • Where was it developed?

Father Ralph March wrote: “If any single man could deserve the title father of the renewed chant it would be Dom Joseph Pothier.”

Matthew Frederes · December 12, 2022

Recent Book! • “The Politics of Plainchant”

Fascinating details from never-before-seen letters recently discovered in southern France!

“Introit” (3rd Sunday of Advent) • Sung According the Church’s Official Rhythm

My humble attempt at singing the Introit for the 3rd Sunday of Advent in accordance with the official rhythm.

Gregorian Rhythm Wars • “Jeff’s Second Response to Patrick” (6 Dec 2022)

You look upon these thousands of manuscripts in much the same way that I view the plainsong editions of Guillaume-Gabriel Nivers.

Matthew Frederes · November 10, 2022

Gregorian Rhythm Wars • “Frederes Feedback”

Why declare that rhythmic signs are permitted if alteration of any kind is unacceptable? It doesn’t make any sense…

Jeff Ostrowski · August 29, 2022

“Did The Pope Really Say That?” • Re: Solesmes Rhythm

My response to the recent article by Professor Charles Weaver.

Dr. Charles Weaver · August 26, 2022

PDF Download • Mocquereau on Trochee Trouble

This can seem like a dry topic, but it actually often deals with practical issues faced by every choirmaster who wants to promote plainchant.

    A Nice Hymn In Spanish
    In my humble opinion, this is a really beautiful hymn in Spanish. If I practice diligently, I’ll be able to pronounce all the words properly. If you’re someone who’s interested in obtaining a melody only version (suitable for your congregational ORDER OF WORSHIP) you can steal that from this.
    —Jeff Ostrowski
    “Music List” • 21st in Ordinary Time (Year C)
    Our choir returns on Sunday, 24 August 2025. Some have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for it, which is the 21st Sunday in Ordinary Time (Year C). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are conveniently stored at the spectacular feasts website. When it comes to the feast of the Assumption (15 August 2025), I have uploaded the music list for that Mass—but not the “bi-lingual” Mass in the evening (Spanish, Latin, and English) which has completely different music.
    —Jeff Ostrowski
    “Entrance Chant” • 21st Sunday Ordin. Time
    You can download the ENTRANCE ANTIPHON in English for the 21st Sunday in Ordinary Time (Year C) which is coming up on 24 August 2025. Corresponding to the vocalist score is this free organ accompaniment. It’s set in a melancholy mode, but if you heard my choir’s female voices singing it your soul would be uplifted beyond belief. If you’re someone who enjoys rehearsal videos, this morning I tried to sing it while simultaneously accompanying my voice on the pipe organ.
    —Jeff Ostrowski

Quick Thoughts

    Solemn “Salve Regina” (Chant)
    How many “S” words can you think of using alliteration? How about Schwann Solemn Salve Score? You can download the SOLEMN SALVE REGINA in Gregorian Chant. The notation follows the official rhythm (EDITIO VATICANA). Canon Jules Van Nuffel, choirmaster of the Cathedral of Saint Rumbold, composed this accompaniment for it (although some feel it isn’t his best work).

    Pope Pius XII Hymnal?
    Have you ever heard of the Pope Pius XII Hymnal? It’s a real book, published in the United States in 1959. Here’s a sample page so you can verify with your own eyes it existed.
    —Corpus Christi Watershed
    “Hybrid” Chant Notation?
    Over the years, many have tried to ‘simplify’ plainsong notation. The O’Fallon Propers attempted to simplify the notation—but ended up making matters worse. Dr. Karl Weinmann tried to do the same in the time of Pope Saint Pius X by replacing each porrectus. You can examine a specimen from his edition and see whether you agree he complicated matters. In particular, look at what he did with éxsules fílii Hévae.

Random Quote

“The Mass, said in Latin, is the same all over the world. Go where you will, the language is the same; and such unity is in itself a great good, far greater than would be the mere understanding of the words.”

— John Henry Newman (1859)
