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.”

Jeff Ostrowski · October 8, 2024

EXT TIME A PRIEST insists that it’s wrong for the choir alone to sing pieces at Mass (because “true” participation means the congregation must sing everything) don’t tell him his statement is in direct violation of SACROSANCTUM CONCILIUM §114. Instead, try taking a different approach. In a respectful and calm manner, say to that priest: “Okay, then the entire congregation must read the Gospel along with you at Mass—because if they just listen while you read the Gospel, they’re not truly participating according to your logic.”

Choral Extensions • It’s incorrect to say the congregation must sing everything at Mass. On the other hand, since the 1950s there’s been a real push for congregational singing. Failing to recognize this is foolish. Indeed, a music director who completely ignores congregational singing runs the risk of being fired by the pastor! In my seminar, Secrets of the Conscientious Choirmaster, I harp on something I call choral extensions. Basically, choral extensions allow a choirmaster to introduce polyphony without getting fired. When it comes to the congregational SANCTUS we use at my parish (which can be sung in Latin, English, or Spanish), the following “extends” it polyphonically:

Freedom To Shape • With regard to SANCTUS XVI, perhaps you’ve noticed how each church sings it in a slightly different manner. That’s because the official edition gives freedom to choirmasters to “shape” each phrase according to its text. For example, here’s how it appeared in a famous edition by Dr. Franz Xaver Mathias (an Alsatian priest). Father Mathias was organist at STRASBURG CATHEDRAL, where he founded the Saint Leo Institute for Church Music in 1913:

Renewal of Challenge • In many recent articles, I’ve been recommending the Brébeuf Catholic Hymnal. I believe this book is indispensable for any serious Catholic choirmaster. (I certainly couldn’t run my choral program without it.) I don’t use the “P-word” word lightly, but I’m comfortable calling the BRÉBEUF HYMNAL peerless. Indeed, one of the main authors for the Church Music Association of America weblog declared (6/10/2022) that the BRÉBEUF HYMNAL “has no parallel and not even any close competitor.” For years, I’ve been searching for a qualified partner willing to debate this assertion over zoom. Today—8 October 2024—I respectfully renew my challenge. Our website garners millions of hits, but so far nobody has accepted my challenge.

    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

I want to say one thing to you strongly, especially today: virginity for the Kingdom of God is not a “no,” it is a “yes!”
