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:

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.

    PDF Download • “Ubi Caritas” (SATB)
    I remember singing “Ubi Cáritas” by Maurice Duruflé at the conservatory. I was deeply moved by it. However, some feel Duruflé’s version isn’t suitable for small choirs since it’s written for 6 voices and the bass tessitura is quite low. That’s why I was absolutely thrilled to discover this “Ubi cáritas” (SATB) for smaller choirs by Énemond Moreau, who studied with OSCAR DEPUYDT (d. 1925), an orphan who became a towering figure of Catholic music. Depuydt’s students include: Flor Peeters (d. 1986); Monsignor Jules Van Nuffel (d. 1953); Arthur Meulemans (d. 1966); Monsignor Jules Vyverman (d. 1989); and Gustaaf Nees (d. 1965). Rehearsal videos for each individual voice await you at #19705. When I came across the astonishing English translation for “Ubi Cáritas” by Monsignor Ronald Knox—matching the Latin’s meter—I decided to add those lyrics as an option (for churches which have banned Latin). My wife and I made this recording to give you some idea how it sounds.

    PDF • “Cantus Mariales” (192 pages)
    Andrea Leal has posted an absolutely pristine scan of CANTUS MARIALES (192 pages) which can be downloaded as a PDF file. To access this treasure, navigate to the frabjous article Andrea posted Monday. The file is being offered completely free of charge. The beginning pages of the book have something not to be missed: viz. a letter from Pope Saint Pius X to Dom Pothier, in which the pope calls Abbat Pothier “a man versed above all others in the science of liturgy, and to whom the cause of Gregorian chant is greatly indebted.”

    Music List • (2nd Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 2nd Sunday of Lent (1 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has magnificent propers. Its somber INTROIT is particularly striking—using a haunting tonality—but the COMMUNION with its fauxbourdon verses is also quite remarkable. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

Quick Thoughts

    Extreme Unction
    Those who search Google for “CCCC MS 079” will discover high resolution images of a medieval Pontificale (“Cambridge, Corpus Christi College, MS 079”). One of the pages contains this absolutely gorgeous depiction of the Sacrament of Extreme Unction.

    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 following question is asked by the Most Reverend Lord Bishop of the Diocese of Chur: May this Diocese’s ancient custom be continued of having the Celebrant in Sung Masses (excepting more solemn Masses) intone the Credo and when he is finished reciting it going on immediately to the offertory and finishing it while the credo is being sung by the choir?” (Dubium of Dec 1909)
