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.”

“Chorister Summer Camp” • Eight Ideas

Every choirmaster should place a high priority on recruitment, otherwise in time he commits a form of “choral contraception”…

“An Unknown Parishioner Approached Me…”

Can modern composers write hymns? Are they stirring?

PDF Download • (Organ Accompaniment)

I created this organ accompaniment booklet for organists who will accompany Vespers on Pentecost Sunday. Feel free to download it; it might give you some ideas or inspiration. Be warned: It looks pretty sloppy. (The organist is the only one who sees it.)

Revelation • “Re: The Official Rhythm”

A very intelligent singer admitted that only yesterday did he finally come to understand what a “melismatic mora vocis” is. Only yesterday did he come to understand the “white notes” (blank spaces). You can see the Introit for Pentecost Sunday only has two instances of MMV (“melismatic mora vocis”).

    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

“Since the English is not meant to be sung, but only to tell people who do not understand Latin what the text means, a simple paraphrase in prose is sufficient. The versions are not always very literal. Literal translations from Latin hymns would often look odd in English. I have tried to give in a readable, generally rhythmic form the real meaning of the text.”

— Fr. Adrian Fortescue (1913)
