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.”

“The old man carried the Child, but the Child led the old man.”

The Antiphon for First Vespers of the Feast of the Purification (February 2nd) is beautiful: “The old man carried the Child, but it was the Child who was guiding the old man. The Virgin bore the Child, and after child-bearing was virgin still: whom she bore, him she adored.” —Senex púerum portábat, puer autem senem […]

A quote from Fr. Valentine Young

I had one brother who was out of the church for quite a few years. When my mother was asked, “Did she worry about him?” I remember her answer: “I don’t worry about him; I just pray for him.” She left that in God’s hands. My mother did not live to see her son return […]

“Theoricam practicamque”

In a book printed by Solesmes Abbey in 1902, “Kyrie Rex Genitor” is also called Theoricam practicamque. Can anyone explain why? And how does that translate into English? “Theoricam practicamque vitam regens Deus Pater.”

This old holy card says it all…

For priests, it reads: “In memory of that day on which was given what is not given to angels—that I should offer God to God.”

A quote from Fr. Valentine

Speaking of “nihil solliciti estis,” Fr. Valentine recently said: “I’ll bet that most people, including myself, have suffered more from things that never happened than from things that actually did happen.” Wise words!

Circle is complete

This is interesting! We have made it all the way around the liturgical year for Vespers organ accompaniments—which means all we have to do now is fill in the “holes,” such as Candlemas.

Fr. Valentine is very sick

I beg you to pray for Fr. Valentine Young, OFM, who I am told is dying (or may possibly have died already). He’s one of the most faithful & generous priests I know. There would be no CCWatershed without Fr. Valentine.

What Palestrina Did With Kyrie II (“Fons Bonitatis”)

Many erroneously believe the Kyrie was the only thing troped, but that’s not even close to true.

    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’.
    —Jeff Ostrowski
    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!
    —Jeff Ostrowski
    “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.

    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. It couldn’t be easier to subscribe!

    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.”
    —Jeff Ostrowski
    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.
    —Jeff Ostrowski

Random Quote

“I would hope there is a place [at Mass] for the avant-garde in the same way I think there has to be a place—and we have to be careful with this—a place for Jazz and a place for Evangelical and all of that. […] On theological grounds, I do think we need interaction with the culture at the level of high art or at the level of more commercial pop culture.”

— Fr. Anthony Ruff (22 June 2016)
