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.”

Video • “Vidi Aquam” Organ Accompaniment By Jeff Ostrowski

Jeff Ostrowski · May 4, 2015

WO SUNDAYS AGO, I had a liturgical experience I’ll never forget, singing the “Vidi Aquam.” When the Celebrant reached the Altar, we hadn’t yet arrived at the Antiphon, so I signaled the choir & organist to psalm tone it. At this point, you’re probably curious why this was a great moment for me. Well, during the 1990s, we had an “authentic” traditional Pastor (ordained in 1956). He said his seminary choir usually sang recto tono on the repeat. His exact words were, “The Vidi Aquam—it’s a pretty little thing but excessively extends past the time required to sprinkle the congregation.” Until a few weeks ago, I never tried his method.

Why was it a great moment? I think it had to do with perfectly matching the liturgical action. Indeed, Pope St. Pius X wrote in 1903: “it must be considered a very grave abuse when the sacred liturgy is made to appear subservient to the music.” By the way, Rev. Andrew Green, OSB, wrote a famous “simplification” of the Vidi Aquam in the 1940s.

Here’s an organ accompaniment I recently created:

Great liturgical moments come at unexpected times. If anyone wants to share a favorite liturgical moment on the CCW Facebook page, I encourage this. 2 For example, I remember a Mass in the Extraordinary Form offered at Corpus Christi Cathedral. The organist played this piece as Bishop René H. Gracida processed in wearing a gorgeous vestment I didn’t even realize bishops were allowed to wear. The seriousness of the Mass—as well as the holy calling of a bishop—was made clear in a mysterious way which assisted my devotion.

TO A LARGE EXTENT, the art of Gregorian accompaniment seems to have been lost. This was one of the reasons our organization went to great lengths making 3,000+ pages of Gregorian accompaniments available back in 2008. We also made sure to place online several versions of the “Method of Gregorian Accompaniment” (1943) by Flor Peeters, which has never been surpassed. After carefully explaining the rationale behind the NOH, Peeters makes it clear that Gregorian chant can be harmonized in countless ways:

Some who attempt to create Gregorian accompaniments completely ignore voice leading—as if voice leading is something which (somehow) doesn’t apply to Gregorian accompaniment. Others attempt to create a very subtle accompaniment, but end up with the opposite. They fail to realize the best way to achieve a subtle accompaniment is to use soft organ stops. To “camp out” on the same chord excessively introduces dissonances an amateur ear might not perceive. In fact, a careful treatment of dissonance is the sine qua non of proper Gregorian accompaniment. This “opposite effect” reminds me of another opposite effect described by Sir David Frost:

 


NOTES FROM THIS ARTICLE:

1   You can also watch it on YouTube or download the Mp3 Recording.

2   I don’t have a Facebook, but I can view comments made on the CCW facebook page.

3   Moreover, if you look at page 2, you’ll see that Catholics in the 14th century did not repeat the entire Antiphon. Rather, they started at the words “et omnes ad quos pervenit”—which is interesting.

    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.

Oh, what sighs I uttered, what tears I shed, to mingle with the waters of the torrent, while I chanted to Thee, O my God, the psalms of Holy Church in the Office of the Dead!
