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.”

“Easy Polyphonic Agnus Dei” • Part 3 of 3

Jeff Ostrowski · September 24, 2021

HERE ARE, OF COURSE, numerous reasons authentic Catholic music has not been universally embraced (yet). One reason is difficult for some to accept: polyphony is frequently sung badly—with unbalanced voices, improper vowels, poor tuning, and so forth. The ability to sight-read music instantly does not guarantee a good performance. Choirs must sing polyphony multiple times before the harmonies “click.” Often, a performance can be greatly improved by simply shuffling your singers around. 1

Piecemeal Polyphony: Here in Los Angeles, we take advantage of a solution called “piecemeal polyphony.” I’ve spoken of this before; it means when we sing a polyphonic KYRIE ELEYSON, we begin by singing the third section (which is usually the hardest), mixing with plainsong in an ABA structure. Then we add the “Christe” section. Finally, we add the first section—and the piece is complete.

Bookmark This Link: Today, I am thrilled to release “Part 3 of 3” for a simple polyphonic setting of the AGNUS DEI. You will want to bookmark this URL, where you can easily access all three sections.

If you want to see a “Piecemeal Kyrie,” you can click here.

Here’s the final section:

*  PDF Download • AGNUS DEI (“Part 3 of 3”)
—The 2nd and 3rd sections are by Father Guerrero, the 1st by Nanino.

Rehearsal videos for each individual voice await you at #59013.

Deep Sadness: My soul is sad because most readers will not click on that 59013 link. As a result, they will miss out on the rehearsal videos for each individual voice; and those are very helpful for volunteer choirs! Mark my words: most readers will not explore that link—which fills me with gloom.


NOTES FROM THIS ARTICLE:

1   This is often called “Doctor James Daugherty’s Solution.” It consists of spending hours shuffling your singers, finding out which voices sound good standing next to one another. Shifting “John Doe” from the left side of someone to his right side can instantly make a tremendous difference—but, of course, this requires time and effort.

    New Bulletin Article • “21 September 2025”
    My pastor requested that I write short articles each week for our parish bulletin. Those responsible for preparing similar write-ups may find a bit of inspiration in these brief columns. The latest article (dated 21 September 2025) discusses some theological items—supported by certain verses in ancient Catholic hymns—and ends by explaining why certain folks become delirious with jealousy when they observe feats by Monsignor Ronald Knox.

    Cheap! Cheap! Cheap!
    It’s always amusing to see old diocesan newspapers—in huge capital letters—advertising the Cheapest Catholic Paper in the United States. The correspondent who sent this to me added: “I can think of certain composers, published by large companies in our own day, who could truthfully brag about the most tawdry compositions in the world!” I wonder what she could have meant by such a cryptic comment…

    Along with so many others, I have deep respect for Dom Gregory Gregory Murray, who produced this clever harmonization (PDF) of “O SANCTISSIMA.” It’s always amazed me that Dom Gregory—a truly inspired composer—was so confused when it came to GREGORIAN CHANT. Throughout his life, he published contradictory statements, veering back-and-forth like a weather vane. Toward the end of his life, he declared: “I see clearly that the need for reform in liturgical music arose, not in the 18th and 19th centuries, but a thousand years earlier—in the 8th and 9th centuries, or even before that. The abuses began, not with Mozart and Haydn, but with those over-enthusiastic medieval musicians who developed the elaborate and flamboyant Gregorian Chant.”

Quick Thoughts

    Karl Keating • “Canonization Questions”
    We were sent an internet statement (screenshot) that’s garnered significant attention, in which KARL KEATING (founder of Catholic Answers) speaks about whether canonizations are infallible. Mr. Keating seems unaware that canonizations are—in the final analysis—a theological opinion. They are not infallible, as explained in this 2014 article by a priest (with a doctorate in theology) who worked for multiple popes. Mr. Keating says: “I’m unaware of such claims arising from any quarter until several recent popes disliked by these Traditionalists were canonized, including John XXIII, Paul VI, and John Paul II. Usually Paul VI receives the most opprobrium.” Mr. Keating is incorrect; e.g. Father John Vianney, several centuries ago, taught clearly that canonizations are not infallible. Archbishop Fulton J. Sheen would be another example, although clearly much more recent than Saint John Vianney.

    Vatican II Changed Wedding Propers?
    It’s often claimed that the wedding propers were changed after Vatican II. As a matter of fact, that is a false claim. The EDITIO VATICANA propers (Introit: Deus Israel) remained the same after Vatican II. However, a new set of propers (Introit: Ecce Deus) was provided for optional use. The same holds true for the feast of Pope Saint Gregory the Great on 3 September: the 1943 propers (Introit: Si díligis me) were provided for optional use, but the traditional PROPRIA MISSAE (Introit: Sacerdótes Dei) were retained; they weren’t gotten rid of. The Ordo Cantus Missae (1970) makes this crystal clear, as does the Missal itself. There was an effort made in the post-conciliar years to eliminate so-called “Neo-Gregorian” chants, but (contrary to popular belief) most were retained: cf. the feast of Christ the King, the feast of the Immaculate Conception, and so forth.

    Solemn “Salve Regina” (Chant)
    How many “S” words can you think of using alliteration? How about Schwann Solemn Salve Score? You can download the SOLEMN SALVE REGINA in Gregorian Chant. The notation follows the official rhythm (EDITIO VATICANA). Canon Jules Van Nuffel, choirmaster of the Cathedral of Saint Rumbold, composed this accompaniment for it (although some feel it isn’t his best work).

Random Quote

“Today the Church has made a big mistake, turning the clock back 500 years with guitars and popular songs. I don’t like it at all. Gregorian Chant is a vital and important tradition of the Church and to waste this—by having guys mix religious words with profane, Western songs—is hugely grave, hugely grave.”

— Maestro Ennio Morricone (10 Sept 2009)
