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 Download • Brief Polyphonic “Asperges Me” for SATB by Father Guerrero (d. 1599)

Jeff Ostrowski · September 20, 2022

ORE THAN FIVE YEARS AGO, I decided to stop 1 composing music—and I can still remember the very day it happened. Dr. Calabrese was visiting Los Angeles, conducting the KYRIE from Father Guerrero’s Missa Beata Mater. Hearing that brief piece with only four voices, something powerful struck me. I realized Guerrero was composing “on a different level.” What I heard was the RESULT of a genuine genius—from boyhood immersed in the world’s most powerful music—composing in a way that makes the human voice sound as magnificent as it can in this world.

Physically Present • Recordings don’t count here. Nor do notes on a page. It’s all about being physically present and hearing Father Guerrero’s pristine counterpoint, his manipulation of overtones, his astounding use of imitation, his uncanny control of dissonance & consonance, and his incomparable rhythmic mastery. It required 400 years of musical experimentation all across Europe to produce the polyphonic miracle of Francisco Guerrero. I realized my efforts at composition were akin to demanding that I play alongside Larry Bird, Wilt Chamberlain, and Michael Jordan.

A Tiny Piece • The following is not even a real piece. Rather, it’s a brief excerpt of a very long composition by Father Guerrero. Nevertheless, I find it utterly captivating, and here’s my attempt at recording all the voices myself (to approximate how it sounds):

M Rehearsal videos for each individual voice await you at #47772.

Sadness: Most readers won’t click on the individual voice parts, and that makes me sad. When we post a “scandalous” liturgical video, we get 40,000 views. I wish we could garner as many views for the rehearsal videos because it’s incumbent upon us to revive authentic sacred music!

1 Technically, I have not completely stopped composing, but the small things I do compose—such as Gregorian accompaniments and short antiphons—are not “composing” in the sense of writing large-scale works (such as symphonies). Once in a blue moon, I still compose a larger work, but always under a fake name. I find that when I use my real name, people don’t tell me the honest truth vis-à-vis their feelings about my compositions. But when they believe somebody else wrote the piece, their praise (or criticism) tends to be more sincere.

President’s Corner

    “Samaritánæ” (3rd Sunday of Lent)
    With regard to the COMMUNION for the 3rd Sunday of Lent (Year A), the Ordo Cantus Missae—which was published in 1969 by the Vatican, bearing Hannibal Bugnini’s signature and approbation in its PREFACE—inexplicably introduced a variant melody and slightly different words, as you can see by this comparison chart. When it comes to such items, they’re always done in secrecy by unnamed people. (Although it is known that Dom Eugène Cardine collaborated in the creation of the GRADUALE SIMPLEX, a book considered by some to be a travesty.)

    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.”

Quick Thoughts

    Grotesque Pairing • “Passion Chorale”
    One of our rarest releases was undoubtably this PDF scan of the complete Pope Pius XII Hymnal (1959) by Father Joseph Roff, a student of Healey Willan. One of the scarcest titles in existence, this book was provided to us by Mr. Peter Meggison. Back in 2018, we scanned each page and uploaded it to our website, making it freely available to everyone. Readers are probably sick of hearing me say this, but just because we upload something that doesn’t necessarily mean it’s wonderful or worthy of imitation. We upload many publications precisely because they are ‘grotesque’, interesting, or revealing. Whereas the Brébeuf Catholic Hymnal had an editorial board that was careful and sensitive vis-à-vis pairing texts with tunes, the Pope Pius XII Hymnal (1959) seems to have been rather reckless in this regard. Please take a look at what they did with the PASSION CHORALE and see whether you agree.

    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.”
