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.”

Jeff Ostrowski · March 9, 2023

EFARIOUS. The word nefarious is defined by the dictionary as: flagrantly wicked or criminal. I would love to know how many readers experienced the same nefarious behavior I did while attending college. Each semester, we were forced to purchase outrageously overpriced textbooks. Each of them cost as much as $130.00—which is the equivalent of $342.36 in today’s currency. When the semester was over, we could sell our books back to the university, but usually only received about $8.00 (!) for each book. To make matters worse, each year the self-same textbooks were published in a “new edition.” The content was virtually identical, but all the formatting was altered, which meant the page numbers no longer corresponded. It’s insane that the perpetrators of this nefarious scheme were never prosecuted. (I really hope this situation no longer exists.)

The Opposite • When one encounters such nefarious acts, it’s easy to lose faith in humanity. Contrariwise, every so often one discovers people who—far from being nefarious—are generous, unselfish, and magnanimous. An example would be the professors at the LEMMENSINSTITUUT, who (at the height of WW2!) produced more than 3,000 pages of Gregorian Chant accompaniments. In an attempt to imitate this same spirit of generosity, we release today a professionally-scanned version of NOH Volume 5:

*  PDF Download • KYRIALE ORGAN ACCOMPANIMENTS (191 pages)
—Volume 5 • Nóva órgani harmónia ad graduále júxta editiónem vaticánam.

The following graphic shows the difference in quality between this professional scan and the version I created during the 1990s:

A few photographs of Volume 5:

“As It Was Intended” • The edition by the LEMMENSINSTITUUT does not follow the illicit elongations of Dom Mocquereau. Rather, they present the official edition as it was intended to be sung by its creators.1 The LEMMENSINSTITUUT marks each MMV (“Melismatic Mora Vocis”) with a tiny little dot. I am preparing an edition that contains little arrows to help singers notice the MMVs. My teacher found the MMVs very annoying to discern. I remember him laughing heartily, saying: “Those who followed the pure VATICANA had to place their noses next to the spine of the book to see whether the required width was actually there.” To him, such a procedure seemed absurd. Indeed, the bishop who baptized our children would often ask me: “Jeff, was it really true that singers had to place the plainsong books next to their noses to determine instances of morae vocis?” Indeed, in his 1939 textbook, Josef Gogniat confirms this method. In the following image, the spine of the book is placed close to one’s nose:

Do you see how this “Gogniat-Spine-Nose” method makes it easy to see whether there is blank space equal to (or exceeding) the width of a single note-head?

1 This may have something to do with the fact that the LEMMENSINSTITUUT is located in Belgium, which is the country where Abbat Pothier took refuge with his monastery during the French anti-clerical persecution.

    PDF Download • “Organ Accompaniment”
    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.

    Simplified Version • “Canon in D” (Pachelbel)
    I published an article on 11 November 2023 called Wedding March For The Lazy Organist, which rather offhandedly made reference to a simplified version I created in 2007 for Pachelbel’s Canon. I often use it as a PROCESSIONAL for weddings and quinceañeras. Many organists say they “hate” Pachelbel’s Canon. But I love it. I think it’s bright and beautiful. I created that ‘simplified version’ for musicians coming to grips with playing the pipe organ. It can be downloaded as a free PDF if you visit Andrea Leal’s article dated 15 August 2022: Manuals Only: Organ Interludes Based on Plainsong. Specifically, it is page 84 in that collection—generously offered as a free PDF download. Johann Pachelbel (d. 1706) was a renowned German organist, violinist, teacher, and composer of over 500 works. A friend of Bach’s family, he taught Johann Christoph Bach (Sebastian Bach’s eldest brother) and lived in his house. Those who read Pachelbel’s biography will notice his connection to two German cities adopted as famous hymn tune names: EISENACH and ERFURT.

    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.

Random Quote

“Participation” in the Mass does not mean hearing our own voices. It means God hearing our voices. Only He knows who is “participating” at Mass. I believe, to compare small things with great, that I “participate” in a work of art when I study it and love it silently.
