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.”

PDF • 2014 Dissertation: “Plainchant Influence on the Liturgical Music of Dr. Marier” (324 pages)

Jeff Ostrowski · February 15, 2023

HIS YEAR, the Sacred Music Symposium is dedicated to Dr. Theodore Marier (d. 2001), and will close with a lecture on his life and music, presented by Richard J. Clark, who currently serves as Director of Music for the Archdiocese of Boston, where Dr. Marier founded a famous choir school in Harvard Square. You should consider attending this year’s Symposium. I can’t reveal all the details yet, but I can assure you: it will be unforgettable. While I personally never met him, Ted Marier seems to have been a Christian husband and father filled with the Lord’s joy. He also “put his money where his mouth is.” That is to say, Dr. Theodore Marier conducted church music in real life, as opposed to just talking about it. Indeed, our Symposium has distinguished itself by its presenters, who (like Marier) have spent their lives conducting choirs in real life.1

Magnificent Dissertation • Our organization has been given permission to post an absolutely magnificent doctoral dissertation by Dr. William Atwood, Diocesan Director of Music for the Diocese of Bridgeport Connecticut. This treatise is a “must read” for anyone who cares about liturgical music in the Catholic Church. Its official title is: “The Influence of Plainchant on the Liturgical Music of Theodore Marier.” However, its 324 pages do much more than simply look at Marier’s music:

An example of the way Dr. Marier incorporated plainsong:

Summary Of Marier’s Life • In his dissertation, Dr. William Atwood mentions an excellent tribute to Dr. Marier, written by the legendary Dr. Robert A. Skeris. You can download that tribute here:

1 Please note: I’m not saying it’s wrong to write articles about authentic sacred music. What I’m saying is this: writing articles is one thing, whereas standing in front of a parish choir in real life is something else entirely. Only those who have stood in front of a parish choir in real life can understand the unique challenges this presents.

    “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.

    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.

    PDF Download • “Quasi Modo Sunday”
    The Introit for “Quasi Modo Sunday” (12 April 2026) is particularly beautiful. The musical score can be downloaded as a PDF file, and so can the organ accompaniment. The official language of the Catholic Church is Latin (whereas Greek is our mother tongue). Vatican II said Gregorian Chant must be given “first place” under normal circumstances. As a result, some parishes will rightly sing the authentic version. On the other hand, because so many USA dioceses disobey the mandate of Vatican II, some musicians sing plainsong in the vernacular. I have attempted to simultaneously accompany myself on the pipe organ while singing the English version. Although very few take advantage of it, the complete Proprium Missae is posted at the flourishing feasts website.

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.

    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!

Random Quote

“A flawless harmonization of Gregorian chant cannot be created by improvisation, no matter the competence and ability of the organist or harmonist.”
