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.”

Huge Announcement! • “Three Voiced Polyphony”

Jeff Ostrowski · October 19, 2021

IFTEEN YEARS AGO, on the feast of Father John Brébeuf—19 October 2006—the Secretary of State granted us recognition as a 501(c)3 public charity in Texas. With gratitude to our Redeemer on our fifteenth anniversary, I’m thrilled to make a huge announcement. A magnificent collection we commissioned for three-part choirs (Soprano, Alto, Bass) can now be purchased directly from Amazon, and we have greatly reduced the price. Depending on how the psalm verses are sung—a decision left to each choirmaster—these pieces can be as long or short as necessary to match the liturgical action. If your choir has more females than males, this collection will thrill you—because all the pieces are written for SAB!

$8.99 per copy • Eligible for Amazon Prime! • 44 pages.

Contemporary Harmonies: Composer Kevin Allen has produced a true masterpiece, make no mistake about it. Some of these pieces are somber and stately. An example would be “Aufer A Me,” and observe how each voice enters on a different scale degree—a superb touch! One way to find out whether a composition is excellent is to take away one or more voices and examine the result. Mr. Allen’s creation certainly passes that test with flying colors, as you can see by listening to a version missing one voice (i.e. with one voice removed). The result is both interesting and pleasing. This is contemporary music, so the “RRR” (Rigid Renaissance Rules) are not followed…yet each voice is eminently singable—an absolute joy!

Rehearsal videos for each individual voice:
“Aufer A Me” • SOPRANO • ALTO • BASS

Small Groups: Some of the pieces are extremely bright—and the following example demonstrates that—and they are very “tuneful” or “catchy.” Once these pieces get into your head, they won’t leave! And that’s okay, because the sacred liturgy is supposed to be something in which we take delight. They sound very good sung by even a handful of singers. Below is a live recording from our 9:00am Sunday Mass—which is sung by a very small group of singers:

Large Groups: On the other hand, these piece sound absolutely spectacular when they are sung by a large group of singers. By the way, in terms of the layout (which includes solfège markings), few books compare in elegance to Matri Divinae Gratiae. Below is live recording from our 11:00am Sunday Mass—which is sung by a large group of volunteer singers:

Rehearsal videos for each individual voice:
“Quam Dilecta” • SOPRANO • ALTO • BASS

This 44-page collection contains:

1. QUAM DILECTA |+ Psalm verses
2. JUSTORUM ANIMAE |+ Psalm verses
3. ERIPE ME |+ Psalm verses
4. SI AMBULAVERO |+ Psalm verses
5. MEMENTO VERBI |+ Psalm verses
6. AUFER A ME + Psalm verses

Supporting The Composer: This collection was commissioned by CORPUS CHRISTI WATERSHED and published in September of 2016. In accordance with our customs, all proceeds which exceed production costs (printing, shipping, and so forth) go directly to the Catholic artist, who maintains copyright. Therefore, when you purchase these books, you are directly supporting Roman Catholic artists who produce works for the Church. We are a 100% volunteer organization.

    Music List • (Palm Sunday, 2026)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for Palm Sunday—a.k.a. “Dominica in palmis de Passione Domini”—which is 29 March 2026. Please feel free to download it as a PDF file if such a thing interests you. The OFFERTORY (Impropérium exspectávit cor meum) is quite moving. Even though the COMMUNION ANTIPHON is relatively simple, the Fauxbourdon makes it sound outstanding.

    Easter • Would You Sing This Hymn?
    He who examines Laudes Dei: a hymnal for Catholic congregations (St. Louis, 1894) will discover this pairing of a hymn for Easter. For the record, this isn’t the only Catholic hymn book to marry that text and melody; e.g. Saint Mark’s Hymnal for Use in the Roman Catholic Church in the United States (Peoria, 1910) does the same thing. Sometimes an unexpected pairing—chosen with sensitivity—can be superb, forcing singers to experience the text in a ‘fresh’ and wonderful way. On the other hand, we sometimes encounter something I’ve called “PERNICIOUS HYMN PAIRINGS.” If you find the subject in intriguing, feel free to peruse an article I published in May of 2023. As always, my email inbox is open if you have a bone to pick with my take.

    Pipe Organ “Answers” in Plainsong?
    In 2003, I copied a book by Félix Bélédin (d. 1895), who was titular organist—from 1841 to 1874—at the Cathedral of Saint John the Baptist in Lyon (France). In 2008, we scanned and uploaded the book to the Lalande Online Library. Nobody knows for sure when the book was published; some believe it first appeared in the 1840s. In any event, one who examines this excerpt, showing GLORIA IX might wonder why it says the organ answers in plainsong. However, the front of the book explains, telling the organist explicitly when to “respond in plainchant.” This is something called organ alternatim. Believe it or not, the pipe organ would take turns with the choir, playing certain texts instrumentally instead of having them sung. I’m not very well-versed in this—pardon the pun—but if memory serves, ORGAN ALTERNATIM was frowned upon by the time of Pope Saint Pius X. Nevertheless, French organists kept doing it, even after it was explicitly condemned as an abuse.

Quick Thoughts

    “Gregorian Chant Quiz” • 24 March 2026
    How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!

    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 Download • “Holy, Holy, Holy”
    For vigil Masses on Saturday (a.k.a. “anticipated” Masses) we use this simpler setting of the “Holy, Holy, Holy” by Monsignor Jules Vyverman (d. 1989), a Belgian priest, organist, composer, and music educator who ultimately succeeded another ‘Jules’ (CANON JULES VAN NUFFEL) as director of the Lemmensinstituut in Belgium. Although I could be wrong, my understanding is that the LEMMENSINSTITUUT eventually merged with “Catholic University of Leuven” (originally founded in 1425). That’s the university Fulton J. Sheen attended.

Random Quote

“The Humanists abominated the rhythmical poetry of the Middle Ages from an exaggerated enthusiasm for ancient classical forms and meters. Hymnody then received its death blow as, on the revision of the Breviary under Pope Urban VIII, the medieval rhythmical hymns were forced into more classical forms by means of so-called corrections.”

— ‘Father Clemens Blume, S.J.’
