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.”

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.

    Pipe Organ “Answers” in Plainsong?
    In 2003, I copied a book by Félix Bélédin (d. 1895), who was titular organist—from 1841 to 1874—at the Cathedral of Saint John the Baptist in Lyon (France). In 2008, we scanned and uploaded the book to the Lalande Online Library. Nobody knows for sure when the book was published; some believe it first appeared in the 1840s. In any event, one who examines this excerpt, showing GLORIA IX might wonder why it says the organ answers in plainsong. However, the front of the book explains, telling the organist explicitly when to “respond in plainchant.” This is something called organ alternatim. Believe it or not, the pipe organ would take turns with the choir, playing certain texts instrumentally instead of having them sung. I’m not very well-versed in this—pardon the pun—but if memory serves, ORGAN ALTERNATIM was frowned upon by the time of Pope Saint Pius X. Nevertheless, French organists kept doing it, even after it was explicitly condemned as an abuse.

    Music List • (5th Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 5th Sunday of Lent (22 March 2026). If such a thing interests you, feel free to download it as a PDF file. Traditionally, this Sunday was called ‘Passion’ Sunday. Starting in 1956, certain church leaders attempted rename both ‘Passion’ Sunday and ‘Palm’ Sunday—but it didn’t work. For example, Monsignor Frederick McManus tried to get people to call PALM SUNDAY “Second Passion Sunday”—but the faithful rejected that. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

    Music List • (Holy Thursday, 2026)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for Holy Thursday, which is 2 April 2026. If such a thing interests you, feel free to download it as a PDF file. I’m not sure I’ve ever heard a more piercingly beautiful INTROIT, and I have come to absolutely love the SATB version of ‘Ubi cáritas’ we are singing (joined by our burgeoning children’s choir). I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

Quick Thoughts

    “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!

    PDF Download • “Ubi Caritas” (SATB)
    I remember singing “Ubi Cáritas” by Maurice Duruflé at the conservatory. I was deeply moved by it. However, some feel Duruflé’s version isn’t suitable for small choirs since it’s written for 6 voices and the bass tessitura is quite low. That’s why I was absolutely thrilled to discover this “Ubi cáritas” (SATB) for smaller choirs by Énemond Moreau, who studied with OSCAR DEPUYDT (d. 1925), an orphan who became a towering figure of Catholic music. Depuydt’s students include: Flor Peeters (d. 1986); Monsignor Jules Van Nuffel (d. 1953); Arthur Meulemans (d. 1966); Monsignor Jules Vyverman (d. 1989); and Gustaaf Nees (d. 1965). Rehearsal videos for each individual voice await you at #19705. When I came across the astonishing English translation for “Ubi Cáritas” by Monsignor Ronald Knox—matching the Latin’s meter—I decided to add those lyrics as an option (for churches which have banned Latin). My wife and I made this recording to give you some idea how it sounds.

    For vigil Masses on Saturday (a.k.a. “anticipated” Masses) we use this simpler setting of the “Holy, Holy, Holy” by Monsignor Jules Vyverman (d. 1989), a Belgian priest, organist, composer, and music educator who ultimately succeeded another ‘Jules’ (CANON JULES VAN NUFFEL) as director of the Lemmensinstituut in Belgium. Although I could be wrong, my understanding is that the LEMMENSINSTITUUT eventually merged with “Catholic University of Leuven” (originally founded in 1425). That’s the university Fulton J. Sheen attended.

Random Quote

Never before have men had so many time-saving devices. Yet, never before have they had so little free time. When the world unnecessarily accelerates, the Church must slow down.
