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.

    Over the past few years, I’ve been harmonizing all the vernacular plainsong Introit settings by the CHAUMONOT COMPOSERS GROUP. This coming Sunday—10 May 2026—is the 6th Sunday of Easter (Year A). The following declaration will probably smack of “blowing my own horn.” However, I’d rank this accompaniment as my best yet. In this rehearsal video, I attempt to sing it while simultaneously accompanying myself on the pipe organ. The musical score [for singers] as well as my organ accompaniment can be downloaded free of charge from the flourishing feasts website.

    “Gregorian Chant Quiz” • 4 May 2026
    A few days ago, the CORPUS CHRISTI WATERSHED Facebook page posted this Gregorian Chant quiz regarding a rubric for the SEQUENCE for the feast of Corpus Christi: “Lauda Sion Salvatórem.” There is no audience more intelligent than ours—yet surprisingly nobody has been able to guess the rubric. Drop me an email with the right answer, and I’ll affirm your brilliance to everyone I encounter!

    “Rare Photographs” • Hannibal Bugnini
    On 2 September 2025, we included in this article extremely rare photographs of Archbishop Hannibal Bugnini taken in Iran circa 1979. Bugnini had initially been banished by the pope to Uruguay, but he refused to obey. [This is interesting, since Bugnini relied upon ‘blind obedience’ when it came to modifications of the ancient liturgy.] After he refused to obey the order from the pope, Hannibal Bugnini was banished to Iran. You can also watch a short video of Hannibal Bugnini in Iran, dated 10 November 1979. That’s about a week after the USA embassy hostage crisis began in Tehran, and Pope Saint John Paul II had sent the leader of the Iranian Revolution a special letter.

Quick Thoughts

    PDF Download • “Anima Christi”
    I received a request for an organ accompaniment I created way back in 2007 for the “Anima Christi” Gregorian Chant. You can download this PDF file which has the score in plainsong followed by a keyboard accompaniment. Many melodies have been paired with “Anima Christi” over the centuries, but this is—perhaps—the most common one.

    PDF • “Liturgical Law” (467 Pages)
    On Good Friday during the middle ages, the pope privately recited THE ENTIRE PSALTER. If you don’t believe me, see for yourself by reading this passage by Dom Charles Augustine Bachofen (d. 1943). His famous book—called “Liturgical Law: A Handbook Of The Roman Liturgy”—was published by the Benjamin Herder Book Company, which was the American arm (operating out of St. Louis, Missouri) of one of the world’s most significant Catholic publishers. Dom Charles Augustine Bachofen was born in Switzerland but spent his career between the Benedictine monasteries at Conception (Missouri) and Mount Angel (Oregon). His 1931 masterpiece, Liturgical Law can be downloaded as a PDF file … 467 pages!

    “Gregorian Chant Quiz” • 24 March 2026
    How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!

Random Quote

“Indeed, we may not hope for real Latin poetry any more, because Latin is now a dead language to all of us. However well a man may read, write, or even speak Latin now, it is always a foreign language to him, acquired artificially. It is no one’s mother tongue. Does a man ever write real poetry in an acquired language?”

— Rev’d Adrian Fortescue (d. 1923)
