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.

    Funeral Music “Template” • For Families
    Many have requested the MUSICAL TEMPLATE for funerals we give to families at our parish. The family of the deceased is usually involved in selecting Number 12 on that sheet. This template was difficult to assemble, because the “Ordo Exsequiarum” has never been translated into English, and the assigned chants and hymns are given in different liturgical books (Lectionary, Gradual, Order of Christian Funerals, and so on). Please notify me if you spot errors or broken links. Readers will be particularly interested in some of the plainsong musical settings, which are truly haunting in their beauty.

    “To Cover Sin With Smooth Names”
    Monsignor Ronald Knox created several English translations of the PSALTER at the request of the Cardinal Archbishop of Westminster. Readers know that the third edition of the Saint Edmund Campion Missal uses a magnificent translation of the ROMAN CANON (and complete Ordo Missae) created in 1950 by Monsignor Knox. What’s interesting is that, when psalms are used as part of the Ordo Missae, he doesn’t simply copy and paste from his other translations. Consider the beautiful turn of phrase he adds to Psalm 140 (which the celebrant prays as he incenses crucifix, relics, and altar): “Lord, set a guard on my mouth, a barrier to fence in my lips, lest my heart turn to thoughts of evil, to cover sin with smooth names.” The 3rd edition of the CAMPION MISSAL is sleek; it fits easily in one’s hand. The print quality is beyond gorgeous. One must see it to believe it! You owe it to yourself—at a minimum—to examine these sample pages from the full-color section.

    Heretical Hymns
    As a public service, perhaps a theologian ought to begin assembling a heretical hymns collection. A liturgical book—for funerals!—published by the Collegeville Press contains this monstrosity by someone named “Delores Dufner.” I can’t tell what the lyrics are trying to convey—can you? I detest ‘hymns’ with lines such the one she came up with: “Let the thirsty come and drink, Share My wine and bread.” Somehow, the publication was granted an IMPRIMATUR by Most Rev’d Jerome Hanus (bishop of Saint Cloud) on 16 August 1989. It’s a nice tune, but paired with a nasty text!

    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

“Until Pope Paul VI, there has not been a single pope who introduced the type of fundamental changes in liturgical forms which we are now witnessing. In fact, we must note that even small changes in the liturgy introduced by a pope have never been readily accepted.”

— Monsignor Klaus Gamber (d. 1989)
