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.”

20 October 2020 • “What we can’t share”

Almighty God has given to us the example of the Jesuit Martyrs of North America, whose feast day we celebrated yesterday. Of course, along with those eight martyrs we honor their associates, e.g Father François Bressani. I can’t share with you the torments Father Bressani underwent at the hands of Iroquois: it is too brutal. […]

19 October 2020 • Feast of Father Brébeuf

When the young priest saw the burnt and bleeding body of his superior, aghast and trembling he spoke the words of St. Paul: “We are made a spectacle to the world, to angels and to men.”

Dom Pothier • “To The Eyes And To The Ears”

For years, I couldn’t understand this business about “the eyes and the ears.” What did Pothier mean? Then it hit me. • Topics include Dom Joseph Pothier, the mora vocis, Abbot Pothier’s brother (Dom Alphonse Pothier), Dom Lucien David, Dom Paul Jausions, and a truly magnificent story about Pope Pius X and Abbot Pothier, which is essential reading+

The “Mora Vocis” • What is that?

The “Pre-NOH” editions have quite an idiosyncratic way of lengthening the neumes. • Fulsome illustrations are included examining and explaining the mora vocis of the Vatican edition; also mentioned is Dom André Mocquereau, Rafael Cardinal Merry del Val, and Pothier’s Liber Gradualis (1883)+

13 October 2020 • Chopin talks Bach

My “pianist pedigree” goes from my teacher through Wiktor Łabuński through Felix Blumenfeld, who studied with Anton Rubinstein. I always considered myself part of the “Bach-Mozart-Chopin school” as opposed to the “Handel-Beethoven-Liszt school.” (Needless to say, there’s great overlap between these schools.) Before giving a concert, Frédéric Chopin would always shut himself up in a […]

12 October 2020 • True Story

Before a Low Mass, the priest ascends the Altar to place the Chalice, check the altar Missal, and do other “preparing” tasks. The organist must be prepared to play here, and—depending upon the priest—this can be of surprising length! For certain priests, I can easily play all six verses of a hymn while he’s doing […]

3 October 2020 • What Kids Lack

Kids these days will never know the adventure of traveling to a special music library, climbing the steps, locating the correct LP record, and placing it into the record player (which had a needle). In the 1990s, this was the only way one could listen to Hofmann’s live recording of Chopin’s 4th Ballade. I have […]

“Spoken vs. Sung Propers” • The Complete History

Lies containing a little truth are the most difficult to quash • Here is the definitive, final exposé on why the “Spoken Propers” don’t match the “Sung Propers.” • In October of 1972, the Bishops’ Committee on the Liturgy falsely equated the “Spoken Propers” with the “Sung Propers” and proclaimed: “These antiphons are too abrupt for communal recitation” • Several official English translations of the Roman Gradual have received the imprimatur multiple times+

    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

“Gregorian chant is the sacred chant, proper and principal of the Roman Church. Therefore, not only can it be used in all liturgical actions, but unless there are mitigating circumstances, it is preferable to use it instead of other kinds of sacred music.”

— §16, De Musica Sacra (1958)
