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!

    Spectacular Communion Setting!
    The FAUXBOURDON setting of the Communion for the Baptism of the Lord (which will occur this coming Sunday) strikes me as quite spectacular. The verses—composed by the fifth century Christian poet, Coelius Sedulius—come from a long alphabetical acrostic and are deservedly famous. The feast of the LORD’S BAPTISM was traditionally the octave day of Epiphany, but in the 1962 kalendar it was made ‘more explicit’ or emphasized. The 1970 MISSALE ROMANUM elevated this feast even further.

    PDF • “Music List” (Sunday, 11 January)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for Feast of the Baptism of the Lord (SUNDAY, 11 January 2025). If such a thing interests you, feel free to download it as a PDF file. The FAUXBOURDON verses for the Communion Antiphon—to say nothing of the antiphon itself—are breathtaking. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the monumental feasts website alongside the official texts in Latin.

    Epiphany Hymn • “New 2-Voice Arrangement”
    The Von Trapp Family Singers loved a melody that was featured heavily (perhaps even “too heavily”) in the Brébeuf Hymnal. It goes by many names, including ALTONA, VOM HIMMEL HOCH, and ERFURT. If you only have one man and one woman singing, you will want to download this arrangement for two voices. It really is a marvelous tune—and it’s especially fitting during the season of Christmas and Epiphany.

    “Reminder” — Month of January (2026)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.

    PDF Download • “In Paradisum” in English
    We always sing the IN PARADISUM in Latin, as printed on this PDF score. I have an appallingly bad memory (meaning I’d be a horrible witness in court). In any event, it’s been brought to my attention that 15 years ago I created this organ accompaniment for the famous and beautiful ‘IN PARADISUM’ Gregorian chant sung in English according to ‘MR3’ (Roman Missal, Third Edition). If anyone desires such a thing, feel free to download and print. Looking back, I wish I’d brought the TENOR and BASS voices into a unison (on B-Natural) for the word “welcome” on the second line.

Random Quote

“With all the powers of modern music open to him, from romanticism through French impressionism to the German and Russian modernists, he is yet able to confine all these contradictory forces on the groundwork of the Gregorian tradition.”

— Theodor Rehmann (on Msgr. Jules Van Nuffel)
