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:

Here’s a rehearsal video: 1

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 • (3rd Sund. Ordinary Time)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for this coming Sunday: the 3rd Sunday in Ordinary Time (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 monumental feasts website alongside the official texts in Latin.

    “Holy Name Hymn” (2-Voice Arrangement)
    When we post a direct URL link, we frequently get thousands of downloads. But when scrolling is required, very few take the time. I mention this because those who click on this URL link and scroll to the bottom can download—completely free of charge—a clever 2-voice arrangement for a famous hymn to the Most Holy Name of Jesus. In a pinch, it can be nicely sung by one male and one female! It will be of interest to those who seek arrangements for two voices.

    PDF Download • Introit (3rd Sn. Ord.)
    This coming Sunday, 25 January 2026, is the 3rd Sunday in Ordinary Time (Year A). The ENTRANCE CHANT (“Dóminus secus mare”) is somewhat rare because it comes from the New Testament. The authentic version in Latin—of astounding antiquity—was jettisoned in 1955 but restored in 1970. This rehearsal video has me attempting to sing the melody while simultaneously accompanying myself on the organ. I encourage you to print off the organ accompaniment (PDF) and play through it because it has extremely ‘happy’ harmonies.

    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.

    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

“Abbat Pothier’s great accomplishment is having returned to the Catholic world—along with the traditional melody—the traditional way of performing it. The foundations laid by this providential man have been accepted by all those who practice Gregorian chant.”

— Dr. Peter Wagner (Commissionis Pontificiæ Gregorianæ Membrum)
