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.”

“Part 1 of 3” • Guerrero Kyrie for Our Lady

Jeff Ostrowski · May 23, 2021

OW THAT CHOIRS are beginning to return—since the government is starting to lift the harsh Covid-19 restrictions they imposed—many directors are looking for pieces to “start out with.” Many great composers wrote settings of the KYRIE ELEYSON in three movements, but did you know it’s not required to sing all three movements at first? We often learn the third movement first, adding a plainsong “Christe” in the middle until we learn the other parts. That makes it: (A) polyphonic Kyrie; (B) plainsong Christe; (C) repeat polyphonic Kyrie. Needless to say, as soon as possible we learn the missing movements.

Here’s section 1 of 3:

*  PDF Download • Part 1 of 3
—We sing the first section, then a plainsong “Christe,” then repeat the polyphonic section.

Rehearsal videos for each individual voice await you at #63627. Notice you have to scroll all the way to the bottom of that page. When I finish all three movements, it will be moved to the top.

Teach Your Choirs This :

This little movement is an excellent way to demonstrate how polyphonic composers based their settings on Gregorian chant. Here is “Kyrie IX” (a.k.a. In Festis Beatæ Mariæ Virginis). Notice the shape of the melody:

In his polyphonic setting of Missa De Beata Virgine II (composed in 1582AD), Guerrero masterfully uses that “motif” or “thema” or “subject”—whatever you want to call it:

Update:

My choir sang the first section very well — now they are eager to learn the other sections! Please stay tuned.

    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

When a friend speaks of his accomplishments and triumphs, he stands at a distance from our heart. When he shares his weaknesses and failings, he’s very near.
