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.”

“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).

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.

    PDF Download • “For Pentecost Sunday”
    Yesterday morning, I recorded myself singing the ENTRANCE CHANT for Pentecost Sunday while simultaneously accompanying myself on the pipe organ. Click here to see how that came out. At the end of the antiphon, there’s a triple Allelúja and I just love the chord at the end of the 2nd iteration. The organ accompaniment—along with the musical score for singers—can be downloaded free of charge at the flourishing feasts website. For the record, the antiphon on Pentecost Sunday doesn’t come from a psalm; it comes from the book of Wisdom.

    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!

Quick Thoughts

    “Thee” + “Thou” + “Thine”
    Few musicians realize that various English translations of Sacred Scripture were granted formal approval by the USCCB and the Vatican for liturgical use in the United States of America. But don’t take my word for it! Here are four documents proving this, which you can examine with your own eyes. Some believe the words “Thine” and “Thou” and “Thee” were forbidden after Vatican II—but that’s incorrect. For example, they’re found in the English translation of the ‘Our Father’ at Mass. Moreover, the Revised Standard Version (Catholic Edition) mentioned in those four documents employs “Thine” and “Thou” and “Thee.” It was published with a FOREWORD by Westminster’s Roman Catholic Archbishop (John Cardinal Heenan).

    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.

Random Quote

“Some of our younger parish clergy read their sermons. This should not be done except for some very special reason. The priest who is not capable of preparing and delivering a brief, clear instruction on Catholic teaching to his people is not fit to be in parish work. The people as a rule do not want to listen to a sermon reader.”

— Archbishop of Baltimore (9 July 1929)
