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.”

Views from the Choir Loft

“Part 2 of 3” • Guerrero Kyrie for Our Lady

Jeff Ostrowski · June 7, 2021

NOWLEDGE GAINED by experience: nothing else can replace this. A presenter could talk for 30 years about “how to train a choir well”—but even that would not replace the actual experience of standing in front of a choir. Anyone with an internet connection can pontificate about choral music—yet almost instantly I can tell if the pontificator has ever stood before a choir in real life. Those who have experience conducting amateur choirs realize that choir rehearsal is like entering a “time warp.” Time moves so quickly, it’s as if rehearsal is over as soon as it begins!

Practical Application: Because of this reality, there’s limited time to work on choral vowels, blending, rhythm, pitch, dynamics, pronunciation, and so forth. Therefore, we often follow the 1958 document of Pope Pius XII, which wisely stated: “In general, it is better to do something well on a small scale than to attempt something elaborate without sufficient resources to do it properly.” Of course, if you have infinite rehearsal time, it would be different—but how many of us have sufficient rehearsal time?

Part 2 of 3: On 23 May 2021, I spoke about a possible way forward in Part 1. Now, I am happy to announce that the “Christe” section is ready—and it is one of the most beautiful compositions I have ever heard, although it’s surprisingly brief:

*  PDF • Father Guerrero “Kyrie Part 2”
—Taken from “De Beata Virgine II” — Edition: Roma 1582AD.

Rehearsal videos for each individual voice await you at #63503.

Notice the very clever way Father Guerrero uses the plainsong motif from Kyrie IX:

Until my choir learns Part 3, we are singing Part 1 (“Kyrie”) twice, Part 2 (“Christe”) twice, and Part 1 (“Kyrie”) once. Please see the link I mentioned above—viz. Part 1—if you are having trouble understanding how we sometimes learn these compositions “piecemeal.”

Please go explore #63503 — I think you will really appreciate what’s there, and also Part 1 is conveniently located right above it. Please go there!

    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.

    “Reminder” — Month of October (2025)
    Those who don’t sign up for our free EMAIL NEWSLETTER miss important notifications. Last week, for example, I sent a message about this job opening for a music director paying $65,000 per year plus benefits (plus weddings & funerals). Notice the job description says: “our vision for sacred music is to move from singing at Mass to truly singing the Mass wherein … especially the propers, ordinaries, and dialogues are given their proper place.” Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

    “Music List” • 27th in Ordinary Time (Year C)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 5 October 2025, which is the 27th 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 spectacular feasts website alongside the official texts in Latin. Readers will want to check out the ENTRANCE CHANT posted there, which has a haunting melody (in the DEUTERUS MODE) and extremely powerful text.

Quick Thoughts

    “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).

    “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
    Did they simplify these hymn harmonies?
    Choirs love to sing the famous & splendid tune called “INNSBRUCK.” Looking through a (Roman Catholic) German hymnal printed in 1952, I discovered what appears to be a simplified version of that hymn. In other words, their harmonization is much less complex than the version found in the Saint Jean de Brébeuf Hymnal (which is suitable for singing by SATB choir). Please download their 1952 harmonization (PDF) and let me know your thoughts. I really like the groovy Germanic INTRODUCTION they added.

Random Quote

“Gregorian chant is the sacred chant, proper and principal of the Roman Church. Therefore, not only can it be used in all liturgical actions, but unless there are mitigating circumstances, it is preferable to use it instead of other kinds of sacred music.”

— §16, De Musica Sacra (1958)
