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:

—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.

    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.

    “O Escam Viatorum” • (Holy Thursday)
    When I was very young, I erroneously believed the four psalms provided by the 1957 Liber Usualis—for Communion on Holy Thursday—were the “correct” music to sing on that first day of the TRIDUUM SACRUM. Those four psalms are: Psalm 22 (Dóminus regit me et nihil mihi déerit); Psalm 71 (Deus judícium tuum regi da); Psalm 103 (Bénedic ánima méa); and Psalm 150 (Laudáte Dóminum in sanctis ejus). It turns out I was way out in left field! While nothing forbids singing those psalms, many other options are equally valid. Our volunteer parish choir will sing this COMMUNION PIECE (joined by our burgeoning children’s choir) on Holy Thursday during Holy Communion. Needless to say, this will happen after the proper antiphon from the GRADUALE ROMANUM has been sung.

Quick Thoughts

    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.

    Stumped by “Episcopalian Hymnal” (1910)
    Some consider Songs of Syon (1910) the greatest Episcopalian hymnal ever printed. As a Roman Catholic, I have no right to weigh in one way or the other. However, this particular page has me stumped. I just know I’ve heard that tune somewhere! If you can help, please email me. I’m talking about the text which begins: “This is the day the Lord hath made; In unbeclouded light array’d.” The book is by George Ratcliffe Woodward, and its complete title is: Songs of Syon: A Collection of Psalms, Hymns, and Spiritual Songs. Back in 2016, Corpus Christi Watershed scanned and uploaded this insanely rare book. For years our website was the sole place one could download it as a PDF file.

    PDF Download • “Holy, Holy, Holy”
    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

“So, as in delirium a man talks in a long-forgotten tongue, now—when her heart is rent—the Catholic Church drops twenty centuries without an effort, and speaks as she spoke underground in Rome, and in Paul’s hired house, and in Crete and Alexandria and Jerusalem.”

— A non-Catholic describing the “Hagios O Theos” of Good Friday in 1906
