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.”

Gregorian Rhythm Wars

Jeff Ostrowski · May 16, 2023

Gregorian Rhythm Wars • “Jeff’s Third Response to Patrick” (16 May 2023)

I don’t think our readers are interested in what we say about Gregorian rhythm—they’re interested only in what we can demonstrate.

Guest Author · April 13, 2023

Gregorian Rhythm Wars • “The Hidden Dactyl”

“Perhaps surprisingly, not one word of three syllables in the ancient Easter sequence ‘Laudes Salvatori voce’ is sung to the rhythm of a dactyl.” —Alasdair Codona

Patrick Williams · April 10, 2023

Gregorian Rhythm Wars • “Non Praevaleat”

“We got to this point because we questioned unfounded claims.” —Patrick Williams

Jeff Ostrowski · March 18, 2023

Sneaky “Salicus” Statements by Solesmes

Let there be no mistake about it: Dom Mocquereau (illicitly) added the “salicus” in hundreds of places where the official edition has none.

Patrick Williams · March 15, 2023

Ictus Fictus!

“Hardly any of this made-up system has its basis in medieval music theory or in the manuscripts themselves.”—Patrick Williams

Dr. Charles Weaver · March 13, 2023

Rhetoric, Number, Measure, and Historicism

The beginnings of a response to mensuralism from the classic Solesmes point of view.

Patrick Williams · March 10, 2023

Gregorian Rhythm Wars • “Clap Your Hands!” (10 Mar 2023)

“With my questions unanswered by those objecting to rhythmic markings based on the oldest sources, it is difficult to take their arguments seriously.” —Patrick Williams

Patrick Williams · February 15, 2023

Gregorian Rhythm Wars • “Liturgical Recitative” (15 Feb 2023)

“May our voices be the instruments through which God breathes new life into the ancient chants of the Catholic Church, decrepit through centuries of neglect and misinterpretation!” —Patrick Williams

Patrick Williams · February 7, 2023

Gregorian Rhythm Wars • “The Normal Syllabic Value” (6 Feb 2023)

“The problem with semiology is not that it neglects the rhythmic indications of the oldest sources, but rather that it overinterprets them, like the nuance theory on steroids.” —Patrick Williams

Patrick Williams · January 2, 2023

Gregorian Rhythm Wars • “Chorale and Chant Carefully Considered” (2 Jan 2023)

“The equalist plainchant of the High Middle Ages is as far removed from the rhythmic chant of the Early Middle Ages as the isometric chorales are from their rhythmic predecessors.” —Patrick Williams

Patrick Williams · December 19, 2022

Gregorian Rhythm Wars • “Patrick’s Third Response to Jeff” (19 Dec 2022)

“The original chant handed down from the Fathers of the Church has strict rhythmic proportions and a steady beat.” —Patrick Williams

Matthew Frederes · December 12, 2022

Recent Book! • “The Politics of Plainchant”

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

Dr. Charles Weaver · December 8, 2022

Gregorian Rhythm Wars • “The Limits of History”

There’s nothing necessarily authentic about the “authentic” rhythm.

PDF Download • “Salve Regina” [Simplex] • An Elegant English Translation (2022)

The incomparable Andrew Hinkley kindly set it to plainchant notation.

President’s Corner

    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.

    “Reminder” — Month of April (2026)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. It couldn’t be easier to subscribe! Just scroll to the bottom of any blog article and enter your email address.
    —Jeff Ostrowski
    Simplified Accompaniment (Easter Hymn)
    Number 36 in the Brébeuf Hymnal is “At the Lamb’s high feast we sing,” an English translation for Ad Cenam Agni Próvidi (which was called “Ad Régias Agni Dapes” starting 1631). As of this morning, you can download a simplified keyboard accompaniment for it. Simply click here and scroll to the bottom. Many organists are forced to serve simultaneously as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult—which explains why choirmasters appreciate these simplified keyboard accompaniments. Sadly, many readers will click that link but forget to scroll to the bottom where the simplified PDF file is located.

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.
    —Jeff Ostrowski
    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!
    —Jeff Ostrowski

Random Quote

“Before any seminarian is accepted for ordination, he must not only strive for chastity but actually achieve it. He must already be living chaste celibacy peacefully and for a prolonged period of time—for if this be lacking, the seminarian and his formators cannot have the requisite confidence that he is called to the celibate life.”

— Archbishop Viganò (16 February 2019)
