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.”

Don’t You Agree About These?

If you want to make Jeff Ostrowski really happy, send him an email with effusive praise about the individual voice recordings for hymn #296. [Soprano, Alto, Tenor, Bass] They came out dazzlingly sensational, don’t you agree?

Choral Vowels? Yes? No?

Here’s a live recording of one of the choral “warm-up” exercises my choir enjoys. It was taken during our rehearsal on 27 January 2023. It’s good to make sure each chord is perfectly in tune and balanced before moving to the next one. That only happens when each singer has the correct vowel. If you […]

Crucial Tip For Choir Directors

Don’t listen to excuses!

Father Herbert Thurston • “I Fear the Man With One Book”

“Sometimes there was the possibility to be faced that a particular line of research could never be followed to a successful conclusion because the evidence was now no longer available.”

26 January 2023 • FEEDBACK

“Jeff, I wanted to personally thank you for your spiritual witness at the Symposium & often blogs that you write too.

Good Friday Polyphony by L. Senfl

The editor of the Sacred Music Magazine recently made available to the public this splendid article by our own Charles Weaver. It includes an edition of polyphony for the GOOD FRIDAY “Reproaches.” Renaissance composers often set the various offices of Holy Week; e.g. readers will probably be familiar with the beautiful TENEBRAE setting by Father […]

“Have We Gone Mainstream?”

A choir member alerted my wife to this video by Scott Hahn. You perhaps recognize a piece that’s been highly promoted by Corpus Christi Watershed: viz. Father Guerrero’s “Sanctus” from Missa Iste Sanctus. I would be interested to learn which choir made the recording (which heavily abbreviates the piece) and whether they used our rehearsal […]

Church Music • “Should It Make Your Congregation Happy or Sad?”

If your priest approaches you after Mass and says the music sounded horrible, it’s incorrect to reply: “Well, that’s how it’s supposed to be.”

Desperate! • Needing help after robbery

A few years ago, I had valuable books stolen. Recovery efforts with law enforcement have failed, so I’m reaching out to our readers. Can somebody help me obtain VOLUME II and VOLUME VIII of the Nova organi harmonia published in the 1940s and 1950s by the LEMMENSINSTITUUT? As far as I can tell, these volumes can’t […]

President’s Corner

    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.”

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 dazzling feasts website alongside the official texts in Latin.

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

The People’s Hymnal suffers from a too literal and awkward translation. And even in the lovely Slovak “Memorare” in The Saint Gregory Hymnal we are still asked to sing “that anyone who sought thee, or made to thee his moan.” Why not “groan” or “bone” or even “phone?” The only thing necessary, it seems, is that it rhyme with “known.”

— Mons. Francis P. Schmitt (1958)
