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.”

Vespers Accompaniment Booklet

A VESPERS ACCOMPANIMENT BOOKLET (20 pages) for this coming Sunday—the 5th Sunday after Easter—can now be downloaded. Those who sing Vespers exactly as given in the ANTIPHONALE ROMANUM will notice that all five psalms for Eastertide are sung according to the exact same tone with the exact same differentiæ. Can someone explain why this is? […]

6 May 2023 • FEEDBACK

Examples of comments we recently received, from all over the globe:   (1) “The Byrd composition your student sung was certainly beautiful. I cannot say how thankful I am for all that CCWATERSHED does in the world of sacred music. The videos, and recorded audios and newsletters are wonderful and beautiful. When you said that […]

FEEDBACK • 26 April 2023

A reader wrote to us about the MELCOMBE HYMN ARTICLE (whose official title was: 1950s Catholicism: Do We Want It Back?) with these kind words: “I so wish there was a CD of your choir. The Introit the other day stays with me all day!”

Jeff Ostrowski · April 24, 2023

It’s Coming!

The draft booklet (320 pages) which will—in a gorgeous hard-copy—be given to participants at the Sacred Music Symposium has been released. If you see any typos, please let me know ASAP. Thank you!

FEEDBACK • “Soul Was Craving”

I got this (personal) message from a choir member. I know we usually avoid sharing personal items, but hopefully this exception is warranted: “Dear Mr. Ostrowski, I read your recent article, “I Came From Somewhere.” I really enjoyed reading it. Thank you for all that you do. I appreciate your sentiments and your work to […]

“Repugnant Pairing” (In My View)

We have spoken many times about the common tunes contained in the Saint Jean de Brébeuf Hymnal. I have suggested that these “shared melodies” are crucial for any director attempting to build a serious choral program in today’s environment. However, I’ve also said hymn pairings must be done with great sensitivity. Take a look at […]

Vespers Booklet (4th Sunday of Lent)

The organ accompaniment booklet (24 pages) which I created for the 4th Sunday of Lent (“Lætare Sunday”) may now be downloaded, for those who desire such a thing.

“The German Palestrina”

Although it’s a hideous accompaniment, I’ve added the harmonization by Monsignor Franz Nekes to this collection of nineteen organ accompaniments for the Easter Sunday Sequence: Víctimæ Pascháli Laudes. Once upon a time, Monsignor Nekes was a very popular composer, known as “The German Palestrina.”

Vespers Booklet, 3rd Sunday of Lent

The organ accompaniment I created for the 3rd Sunday of Lent (“Extraordinary Form”) may now be downloaded, if anyone is interested in this.

Weeping For Joy! (We Hope!)

Listening to this Easter Alleluia—an SATB arrangement I made twenty years ago based on the work of Monsignor Jules Van Nuffel—one of our readers left this comment: “I get tears in my eyes each time I sing to this hymn.” I hope this person is weeping for joy!

“The Times” mentions CCW

We were mentioned in article in an article by “The Times” (United Kingdom), as you can see here.

An Interview on Mocquereau’s Method

I recently appeared on Square Notes, the Sacred Music Podcast to discuss some of the basics of Dom Mocquereau’s system of Gregorian rhythm. It’s impossible to give a full treatment to such a complex topic in a mere forty minutes, but I touched on a lot of the foundational ideas, with especial emphasis on the […]

Three-Voice Piece You’ll Love!

To help my volunteer choir members learn, I have attempted to record all the vocal parts for Justorum Animae, composed for SOPRANO, ALTO, and BASS. It’s from a brilliant collection by Kevin Allen called Matri Divinae Gratiae. You can hear my attempt by visiting this website and scrolling down to “Justorum Animæ.” My singers really […]

    “Music List” • 29th in Ordinary Time (Year C)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 19 October 2025, which is the 29th Sunday in Ordinary Time (Year C). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are conveniently stored at the sensational feasts website alongside the official texts in Latin.

    Liturgical Round (“Canon”) in C-Major
    Those who direct children’s choirs are always on the lookout for repertoire that’s dignified, inspired, and pleasing—yet still within reach of young choristers. Such directors will want to investigate this haunting liturgical round (PDF download) which has been married to the KYRIE from Mass VI (EDITIO VATICANA). I have provided an accompaniment, but it’s only for use during rehearsal; i.e. when teaching this round to your choristers. I also provided an organ accompaniment for the KYRIE—which some know by its trope (Kyrie Rex Genitor)—so that your congregation can take part when this round is used as a choral extension during Mass.
    —Jeff Ostrowski
    Latin Liturgy Association
    We note with pleasure that Mrs. Regina Morris, president of the Latin Liturgy Association, has featured—on page 4 of Volume CXXIX of their official newsletter—the three (3) terrific versions of the Stations of the Cross found in the Brébeuf Hymnal. One of the main authors for the blog of the Church Music Association of America said (6/10/2019) about this pew book: “It is such a fantastic hymnal that it deserves to be in the pews of every Catholic church.”

Quick Thoughts

    New Bulletin Article • “12 October 2025”
    My pastor requested that I write short articles each week for our parish bulletin. Those responsible for preparing similar write-ups may find a bit of inspiration in these brief columns. The latest article (dated 12 October 2025) talks about an ‘irony’ or ‘paradox’ regarding the 1960s switch to a wider use (amplior locus) of vernacular in the liturgy.
    —Jeff Ostrowski
    “American Catholic Hymnal” (1991)
    The American Catholic Hymnal, with IMPRIMATUR granted (25 April 1991) by the Archdiocese of Chicago, is like a compendium of every horrible idea from the 1980s. Imagine being forced to stand all through Communion (even afterwards) when those self-same ‘enlightened’ liturgists moved the SEQUENCE before the Alleluia to make sure congregations wouldn’t have to stand during it. (Even worse, everything about the SEQUENCE—including its name—means it should follow the Alleluia.) And imagine endlessly repeating “Alleluia” during Holy Communion at every single Mass. It was all part of an effort to convince people that Holy Communion was historically a procession (which it wasn’t).
    —Jeff Ostrowski
    “Canonic” • Ralph Vaughan Williams
    Fifty years ago, Dr. Theodore Marier made available this clever arrangement (PDF) of “Come down, O love divine” by P. R. Dietterich. The melody was composed in 1906 by Ralph Vaughan Williams (d. 1958) and named in honor of of his birthplace: DOWN AMPNEY. The arrangement isn’t a strict canon, but it does remind one of a canon since the pipe organ employs “points of imitation.” The melody and text are #709 in the Brébeuf Catholic Hymnal.
    —Jeff Ostrowski
