Corpus Christi Watershed

Jesus said to them: “I have come into this world so that a sentence may fall upon it, that those who are blind should see, and those who see should become blind. If you were blind, you would not be guilty. It is because you protest, ‘We can see clearly,’ that you cannot be rid of your guilt.”

Why Text Only?

Why do hymns in the Saint Jean de Brébeuf Hymnal give so many optional “text only” versions of the hymns? It’s easier to demonstrate than explain. Consider Hymn #24, which allows the director to choose a wonderful melody and easily apply it to the text. Hymnal editors knew about the value of “text only” versions […]

“Choral Eavesdropping” • 15 Sept. 2022

If you enjoy eavesdropping, here’s a rehearsal excerpt (mp3) of my volunteers singing the exercise I posted last week. This is the second time we’ve used it, and I can definitely hear improvement. You can download this choral warm-up for free.

PDF • “Organ Interludes” (Manuals Only)

In graduate school, one is taught a valuable lesson: if you emphasize everything, nothing is emphasized. In other words, putting every other word in bold or italic (or both) wrecks your paper. I never to use the word “best”—but today I make an exception. The book of organ interludes released today by my colleague is […]

For the Upcoming Choir Season!

Last week, I posted an SATB choral setting of the SANCTUS in a ‘contemporary’ style. You might want to consider this piece for two reasons: (1) It’s extremely brief; (2) Free rehearsal videos are available for each individual part. The piece is by Father Lhoumeau.

PDF Download • “Sunday Vespers” (22 pages)

In spite of its imperfections, creating this (draft) booklet required much more effort than I had anticipated.

11 July 2022 • FEEDBACK

Someone who heard the CCW plainsong recordings with NOH accompaniment says: “For years I have travelled the continents and crossed the oceans of Gregorian chant in search of a composition and interpretation as sublime as this. The text and the melody are interwoven in a game of mirrors with the interpreters, the singer and the […]

Gregorian Chant • Its “True” Rhythm

I’m dumbstruck (with joy) to see that my recent video presentation on plainsong rhythm has garnered quite a number of “views” on VIMEO. I also made the full presentation available on YouTube, and—as I write these words—it has collected 700+ views. How cool is it that folks are still interested in the rhythm of Cantus […]

Across the Pacific • Alto is “Raving”

From Asia: “I held choir rehearsal yesterday and one of the choir members (singing Alto) was just raving about how she loved the layout of the Brébeuf Choral Supplement because she didn’t have to look up and down for both music and verse—and she loved the ease with which she could sing her part because […]

Alabama Assessment!

We received this evaluation of Symposium 2022 from an Alabama participant: “Oh, how the Symposium echoed the words of Cardinal Merry Del Val: …choosing only what is most conformed to Thy glory, which is my final aim. In one short and fast paced week, the faculty and attendees showed me the hand of God and […]

PDF Download • Trinity Sunday (22 pages)

Feel free to download this Organ Accompaniment Booklet for Trinity Sunday (Second Vespers). Notice how the modes progress by number. Psalm 1 is mode 1; Psalm 2 is mode 2; Psalm 3 is mode 3; Psalm 4 is mode 4; Psalm 5 is mode 5. I am told by an expert that other feasts (such […]

10 June 2022 • “Official” rhythm of plainsong

I continue to search for the most beautiful way to present the “pure” Editio Vaticana scores. (Technically, the “pure” rhythm of the official edition is what everyone is supposed to use.) You can download my latest attempt, which is the Introit for this coming Sunday: Feast of the Most Holy Trinity. Because this is not […]

7 June 2022 • FEEDBACK

From Chelan, Washington: “CCWatershed is a God-sent resource that I can’t function without! Such great work by the team to bring beauty back to our liturgy!” From Gainesville, Florida: “I am so appreciative of the work, of my brothers and sisters in music!” From Troutman, North Carolina: “Keep up the excellent work in service of the Liturgy!”

PDF Download • (Organ Accompaniment)

I created this organ accompaniment booklet for organists who will accompany Vespers on Pentecost Sunday. Feel free to download it; it might give you some ideas or inspiration. Be warned: It looks pretty sloppy. (The organist is the only one who sees it.)

Revelation • “Re: The Official Rhythm”

A very intelligent singer admitted that only yesterday did he finally come to understand what a “melismatic mora vocis” is. Only yesterday did he come to understand the “white notes” (blank spaces). You can see the Introit for Pentecost Sunday only has two instances of MMV (“melismatic mora vocis”).

    “Music List” • 4th Sunday of Easter (Year C)
    Some have expressed interest in perusing the ORDER OF MUSIC I prepared for the 4th Sunday of Easter (11 May 2025). If such a thing interests you, feel free to download it as a PDF file. I don’t know a more gorgeous ENTRANCE CHANT than the one given there: Misericórdia Dómini Plena Est Terra.
    —Jeff Ostrowski
    “Entrance Chant” • 4th Sunday of Easter
    You can download the ENTRANCE ANTIPHON in English for the 4th Sunday of Easter (11 May 2025). Corresponding to the vocalist score is this free organ accompaniment. The English adaptation matches the authentic version (Misericórdia Dómini), which is in a somber yet gorgeous mode. If you’re someone who enjoys rehearsal videos, this morning I tried to sing it while simultaneously accompanying my voice on the pipe organ.
    —Jeff Ostrowski
    Music List • “Repertoire for Weddings”
    Not everyone thinks about sacred music 24/7 like we do. When couples are getting married, they often request “suggestions” or “guidance” or a “template” for their musical selections. I created this music list with repertoire suggestions for Catholic weddings. Please feel free to download it if you believe it might give you some ideas or inspiration.
    —Jeff Ostrowski

Quick Thoughts

    Antiphons Don’t Match?
    A reader wants to know why the Entrance and Communion antiphons in certain publications deviate from what’s prescribed by the GRADUALE ROMANUM published after Vatican II. Click here to read our answer. The short answer is: the Adalbert Propers were never intended to be sung. They were intended for private Masses only (or Masses without music). The “Graduale Parvum,” published by the John Henry Newman Institute of Liturgical Music in 2023, mostly uses the Adalbert Propers—but sometimes uses the GRADUALE text: e.g. Solemnity of Saints Peter and Paul (29 June).
    —Corpus Christi Watershed
    When to Sit, Stand and Kneel like it’s 1962
    There are lots of different guides to postures for Mass, but I couldn’t find one which matched our local Latin Mass, so I made this one: sit-stand-kneel-crop
    —Veronica Brandt
    The Funeral Rites of the Graduale Romanum
    Lately I have been paging through the 1974 Graduale Romanum (see p. 678 ff.) and have been fascinated by the funeral rites found therein, especially the simply-beautiful Psalmody that is appointed for all the different occasions before and after the funeral Mass: at the vigil/wake, at the house of the deceased, processing to the church, at the church, processing to the cemetery, and at the cemetery. Would that this “stational Psalmody” of the Novus Ordo funeral rites saw wider usage! If you or anyone you know have ever used it, please do let me know.
    —Daniel Tucker

Random Quote

“Chants closely related to the readings should, of course, be appropriately transferred for use with these readings. For pastoral reasons also there is an option regarding the chants for the Proper of Seasons: namely, as circumstances suggest, to replace the text proper to a day with another text belonging to the same season.”

— Ordo Cantus Missae (1971)
