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.”

Hymn for the Ascension

Here is a ‘live’ recording from the Mass on Ascension Thursday (2024): Hymn for the Ascension. I could not be prouder of this parish choir, which consists 100% of volunteers. To learn more about this hymn, please visit #704 in the hymn portal. I have argued that—in addition to CARMEN GREGORIANUM, organ music, and polyphony—hymns […]

“Praise To The Lord” • Simple Accomp.

In case you missed the full article I posted the other day on Views from the Choir Loft, feel free to download a PDF version of my simplified organ accompaniment for the famous hymn “Praise To The Lord,” which is often paired with LOBE DEN HERREN. I’m toying with the idea of creating a whole […]

PDF Download • “Ad Regias” Hymn

Upon hearing this special rendition of the ancient Roman Catholic hymn for Eastertide known as “Ad Régias Agni Dapes” several readers requested the score. You may now download the PDF Score (4 pages) completely free of charge. [Rehearsal videos for each individual part are waiting for you at #33013.] For the record, prior to 1632AD […]

Organ Accompaniment Booklet (20 pages)

This coming Sunday in the Extraordinary Form will be the Fifth Sunday after Easter. Each week, everyone can freely visit this page, downloading such booklets (as it were) directly from the source. Nevertheless, I’d like to draw your attention to the ORGAN ACCOMPANIMENT BOOKLET (20 pages) for Vespers in the Extraordinary Form: Dominica V Post […]

Random Psalm Tone! • (1962 Weddings)

I believe it’s better to sing a Psalm Tone with excellence rather than attempt the authentic CARMEN GREGORIANUM (Gregorian Chant) in a plodding, lifeless, poorly-executed way. To that end, I have created this Fifth Mode Psalm Tone version for the COMMUNION CHANT assigned to 1962 Missal weddings. The Nuptial Mass is sometimes called “Pro Sponso […]

Can Your Choir Members Do This?

How many of your choir members can do this? (a) Recite the Tantum Ergo from memory; (b) Explain where the piece comes from and when specifically—during HOLY WEEK—it’s used; (c) Provide a literal translation (from memory, without looking in a book). This nifty one-page sheet (PDF) might be worth downloading if you’re worried some of […]

“Banish Wrong Notes!” • Hymns Simplified

In the past, I’ve mentioned how I can’t stand hearing wrong notes. I was playing LLANFAIR the other day, and I was hitting wrong notes. Earlier today, I created a simplified version which you can download for free. This famous tune (“LLANFAIR”) is often used on the feast of the Ascension, with “Hail the Day […]

“Jesus Christ is Ris’n Today” (Simplified)

I hate hearing organists play wrong notes. I invite you to download this simplified organ accompaniment for hymn #699 in the Saint Jean de Brébeuf Hymnal. The hymn is “Jesus Christ Is Risen Today.” I’m toying with the idea of creating a whole bunch of these, to help amateur organists. The last one I uploaded was […]

“Strangest Of All…” • (Fortescue)

In his illustrious 1912 tome—The Mass: A Study Of The Roman Liturgy—Father Adrian Fortescue spoke of sequences, writing: “Strangest of all were the vernacular sequences in France and Germany, or those partly vernacular and partly Latin.” Our volunteer choir experimented with that on Holy Thursday, mixing Latin verses with an English refrain. For the record, […]

William Byrd • “Mass for Five Voices”

Working with volunteers can be discouraging, but always remember there’s light at the end of the tunnel. Yesterday, during PALM SUNDAY MASS, our 100% volunteer choir pulled out the SANCTUS from William Byrd’s “Mass for Five Voices.”  This colossal performance was the result. (They literally didn’t know I was going to have them sing that […]

“Simplified” Accomp. (1,700 downloads)

The last one I uploaded was downloaded more than 1,700 times in a matter of hours. Therefore, folks seem interested in such a project.

“Lenten Polyphony for Two Voices”

On 28 February 2024, we posted this article with two women singing at Mass. Specifically, they were singing a piece for Lent called “Open, O Hard and Sinful Heart.” Since that time, the video has garnered thousands of views on YouTube and reached more than 34,000 on Facebook. If you’d like to download a special […]

Re: “Sacred Music Symposium” (2024)

Today, an announcement was sent out regarding the 2024 Sacred Music Symposium. If you’re not subscribed to our mailing list, you missed this announcement. I’ve tried everything I can think of to get folks to subscribe to our mailing list. Simply scroll to the bottom of any CCW article and enter your email address. It […]

“Simplified” Keyboard Accompaniment

Are you an inexperienced organist? Were you formally a pianist? I invite you to download this simplified organ accompaniment for hymn #124 in the Saint Jean de Brébeuf Hymnal. I’m toying with the idea of creating a whole bunch of these, to benefit amateur organists. What is your opinion of such a project? Let me […]

President’s Corner

    “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.
    —Jeff Ostrowski
    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

Random Quote

Is this the dumbest statement ever written? “When considering texts for his motets, Gombert obtained his inspiration from Scripture—such as the Psalms—as opposed to the liturgy of the Roman Catholic church.”
