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.”

27 August 2023 • Nine Merry Men!

Half a decade has passed since nine (9) colleagues from Corpus Christi Watershed contributed texts, melodies, and harmonizations to a special hymn book in honor of North America’s patron saint, Father John Brébeuf. The website promoting it was massively overdue for a facelift. As of a few minutes ago, I can report that it’s been […]

24 August 2023 • FEEDBACK

From a female choirmaster: “Thank you for your recent article, Jeff. We here in _____ absolutely love our Brébeuf hymnals! They have saved my life as a choir director! ☺️ The ease with which my choir members plunge into a new hymn using the ‘common melodies technique’ is so wonderful. You can see the relief on […]

Shameful Quote

Some feel the most irresponsible 1960s reformer was Fr. Godfrey Diekmann. The Second Vatican Council had solemnly declared: “In accordance with the centuries-old tradition of the Latin rite, the Latin language is to be retained by clerics in the divine office.” In spite of this clear directive, Diekmann (3 March 1964) wrote: “What young candidate […]

PDF Booklet • 25 Pages!

As of a few minutes ago, you may go here to download the organ accompaniment booklet (25 pages) I created for the feast of the TRANSFIGURATION. Obviously, that feast will not take place for another year. Nevertheless, several techniques I used may be of interest to those who create liturgical booklets.

    PDF • “Music List” (4th Sunday of Advent)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 21 December 2025, which is the 4th Sunday of Advent (Year A). If such a thing interests you, feel free to download it as a PDF file. The ENTRANCE CHANT is the famous “Roráte Coeli” and the fauxbourdon setting of the COMMUNION is exquisite. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.
    —Jeff Ostrowski
    PDF • Our Lady of Guadalupe (12 Dec.)
    The Responsorial Psalm may be downloaded as a PDF file (organist & vocalist) for 12 December, which is the Feast of Our Lady of Guadalupe. When it comes to the formulary for this Mass, it’s astounding how infrequently it’s included in official books. Prior to Vatican II, one had to search through “supplemental material” printed in the back of hand-missals and graduals. But since 1970, the feast is virtually nonexistent. According to the UNIVERSAL KALENDAR, 12 December is the “Feast of Saint Jane Frances De Chantal, Religious” (Die 12 decembris: S. Ioannæ Franciscæ de Chantal, religiosæ). Why should that feast overpower Our Lady of Guadalupe? In the United States, OLG is celebrated—and I’d assume in Mexico, Central America, South America, and Canada—but, as I said, the Propria Missae are virtually impossible to locate. I possess only three books which mention this feast.

    Simplified Accompaniment (Advent Hymn)
    Many organists are forced to simultaneously serve as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult. I invite you to download this simplified organ accompaniment (PDF) which in the Father Brébeuf Hymnal is hymn #661: “Come, Thou Long-Expected Jesus” (for ADVENT). I’m toying with the idea of creating a whole bunch of these, to help amateur organists. The last one I uploaded was downloaded more than 2,900 times in a matter of hours—so there appears to be interest.

Quick Thoughts

    PDF Download • “Santo Santo Santo”
    Those searching for a dignified, brief, simple, bright setting of SANCTUS in Spanish (“Santo Santo Santo”) are invited to download this Setting in honor of Saint John Brébeuf (organist & vocalist). I wonder if there would be any interest in me recording a rehearsal video for this piece.

    Pope Leo XIV on Sacred Music
    On 5 December 2025, Pope Leo XIV made this declaration with regard to liturgical music.

    “Translations Approved for Liturgical Use”
    According to the newsletter for USSCB’s Committee on Divine Worship dated September 1996, there are three (3) translations of the Bible which can be used in the sacred liturgy in the United States. You can read this information with your own eyes. It seems the USCCB and also Rome fully approved the so-called NRSV (“New Revised Standard Version”) on 13 November 1991 and 6 April 1992 but this permission was then withdrawn in 1994.

Random Quote

It is necessary to address Bishop Trautman’s statement that “recent directives of the Congregation aimed at ICEL’s work appear to require a word-for-word, syntax-for-syntax correspondence between the Latin and the English texts.” I am happy to clarify that this certainly is not the intention of the Congregation, since the successful translation of the liturgical texts cannot be achieved by such a wooden mechanism.
