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.”

“Is This an Error?” • The Answer Is Complicated

Jeff Ostrowski · October 13, 2023

N A RECENT article, I said that pedantry can only take the conscientious choirmaster so far. Specifically, I provided three brief audio clips of Glenn Gould breaking the “commitment rule” in three different fugues. For the record, Gould’s teacher was a man named Alberto Guerrero (d. 1959); and you’ll see why I mention this random tidbit if you keep reading. When it comes to the subject of text underlay in Renaissance polyphony, pedantry can sometimes lead us down a false path.

Consider This Example • One of my professors at the conservatory used to say: “An example is worth 1,000 words.” Therefore, consider the following example, which comes from the GLORIA of “Missa Iste Sanctus” by Father Francisco Guerrero (considered one of the greatest composers of all time):

Is This An Error? • Surely you noticed a discrepancy involving Déus Páter omnípotens. Many would assume it’s an error in text underlay … but beware! The reality is—and this is not easy for certain people to accept—such discrepancies happen frequently in Renaissance polyphony. As I explained in the aforementioned article, music’s ultimate purpose is not pedantry.

Before you “correct” the score, consider the following:

(1) Sometimes composers didn’t write out the text underlay for each voice. This seems to have been a “convention”—that is to say, it doesn’t automatically mean instruments (instead of voices) would play that line.

(2) Sometimes the composer’s text underlay was thwarted by his publisher. In graduate school they taught us that not all publishers respected the wishes of composers when it comes to text underlay.

(3) There are instances where Father Guerrero, in a subsequent edition, would make changes to the text underlay—and sometimes these changes were quite interesting! That would suggest even the greatest of composers felt there was some “freedom” involved.

(4) It’s entirely possible that “discrepancies” such as the one shown above are not errors at all. Indeed, the composer may have had a reason for placing particular words at particular spots. As a composer, my text underlay is often determined by vowel sounds I desire at particular moments.

(5) It is absolutely possible that false text underlay crept in because of human error. We know the publishers sometimes paid a “proofreader” who looked over the part books before publication. It is eminently reasonable to assume some proofreaders were more skilled than others.

(6) There was an early composer who stuffed all his compositions into a box shortly before he died. Many years later, the box was opened up. In that case, we can be sure of the composer’s text underlay! But this is seldom the case. If memory serves, Palestrina married a rich woman. Because of this wealth, he was able to publish his own music (which probably means his text underlay is more accurate).

Try this one on for size!

Article Summary • What I’ve written constitutes the final, irrevocable, unassailable, and indisputable approach to text underlay. 😁 I’m kidding, of course! This subject is fraught with difficulty.

    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

    “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.

    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

“With all the powers of modern music open to him, from romanticism through French impressionism to the German and Russian modernists, he is yet able to confine all these contradictory forces on the groundwork of the Gregorian tradition.”

— Theodor Rehmann (on Msgr. Jules Van Nuffel)
