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.”

What Can You Do With Three Voices?

Jeff Ostrowski · July 15, 2024

AITRIN. Her name is Kaitrin—and she’s one of the greatest church musicians I know. I suspect she wouldn’t identify primarily as a church musician. Rather, I suspect she would emphasize that she’s a wife and mother of five beautiful children. I’ve had the privilege of working with her (and hope to learn a lot more from her in the future). What Kaitrin has accomplished musically at her Catholic parish over the last decade is nothing short of miraculous. As we’ve mentioned in the past, the internet is full of ‘expert’ Catholic authors* who spend hours each day complaining about the sacred liturgy’s deficiencies yet are unwilling to lift a finger in real life to improve the situation. Kaitrin has taken a different approach. She has “gotten her hands dirty”—with her parish as the beneficiary.

Only Three Voices • What can the conscientious choirmaster accomplish with only three voices? Yesterday, I was present when Kaitrin and her two daughters sang (during a 5:00pm Sunday Mass) a three-voice motet called O Sacrum Convivium by Kevin Allen. Our 1-year-old baby is the one you hear crying in the pews—and I apologize for that:

Here’s the direct URL link.

Talent Runs In The Family • Kaitrin’s daughter made a really beautiful arrangement of “Soul of my Savior” (Ánima Christi Sanctífica Me), but the tune is different from the one found in Brébeuf Catholic Hymnal. Here’s an excerpt from yesterday:

Here’s the direct URL link.

* Many spend an inordinate amount of time publishing articles explaining how brilliant they are, while everyone else is (according to them) an uncultured, unenlightened Philistine. Yet the same folks who consider themselves to be “the world’s leading liturgical experts” make rather basic mistakes with an alarming frequency. Someday, I’d like to give specific examples—if I can find the time—although that’s a dangerous game because such authors take themselves very seriously. The fact is, we musicians tend to be some of the best liturgists because our livelihood depends upon a practical knowledge of the sacred liturgy.

    Music List • (1st Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I’ve prepared for this coming Sunday—22 February 2026—the 1st Sunday of Lent (Year A). 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 available at the outstanding feasts website alongside the official texts in Latin. I spent an enormous amount of time preparing this ORDER OF MUSIC—because the children’s choir will join us—and some of its components came out great. For example, the COMMUNION ANTIPHON with Fauxbourdon is utterly resplendent, yet still ‘Lenten’.

    2-Voice Arrangement for Lent
    Those seeking a two-voice arrangement for LENT and PASSIONTIDE should click here and scroll down. It’s based on number 775 in the Brébeuf Hymnal, with an enchanting melody written by Kevin Allen (the legendary American composer of sacred music). That text—“Pendens In Crucis Cornibus”—is often used for the Feast of our Lady of Sorrows. That link is important because, in addition to the musical score, it provides free rehearsal videos for each individual voice: something volunteer choirs appreciate!

    “Sanctus VIII” • Organ Accompaniment
    A few days ago, I composed this organ harmonization for SANCTUS VIII. This Mass is traditionally called Missa de ángelis or “Mass of the angels.” In French, it is Messe de Anges. You can evaluate my attempt to simultaneously accompany myself on the pipe organ (click here) while singing the melody. My parish is currently singing this setting.

    PDF Chart • “Plainsong Rhythm”
    I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”

    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.

Random Quote

I basically don’t favor Cardinal Kasper’s proposal; I don’t think it’s coherent. To my mind, “indissoluble” means “unbreakable.”
