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.”

PDF Download • Brief Polyphonic “Asperges Me” for SATB by Father Guerrero (d. 1599)

Jeff Ostrowski · September 20, 2022

ORE THAN FIVE YEARS AGO, I decided to stop 1 composing music—and I can still remember the very day it happened. Dr. Calabrese was visiting Los Angeles, conducting the KYRIE from Father Guerrero’s Missa Beata Mater. Hearing that brief piece with only four voices, something powerful struck me. I realized Guerrero was composing “on a different level.” What I heard was the RESULT of a genuine genius—from boyhood immersed in the world’s most powerful music—composing in a way that makes the human voice sound as magnificent as it can in this world.

Physically Present • Recordings don’t count here. Nor do notes on a page. It’s all about being physically present and hearing Father Guerrero’s pristine counterpoint, his manipulation of overtones, his astounding use of imitation, his uncanny control of dissonance & consonance, and his incomparable rhythmic mastery. It required 400 years of musical experimentation all across Europe to produce the polyphonic miracle of Francisco Guerrero. I realized my efforts at composition were akin to demanding that I play alongside Larry Bird, Wilt Chamberlain, and Michael Jordan.

A Tiny Piece • The following is not even a real piece. Rather, it’s a brief excerpt of a very long composition by Father Guerrero. Nevertheless, I find it utterly captivating, and here’s my attempt at recording all the voices myself (to approximate how it sounds):

M Rehearsal videos for each individual voice await you at #47772.

Sadness: Most readers won’t click on the individual voice parts, and that makes me sad. When we post a “scandalous” liturgical video, we get 40,000 views. I wish we could garner as many views for the rehearsal videos because it’s incumbent upon us to revive authentic sacred music!

1 Technically, I have not completely stopped composing, but the small things I do compose—such as Gregorian accompaniments and short antiphons—are not “composing” in the sense of writing large-scale works (such as symphonies). Once in a blue moon, I still compose a larger work, but always under a fake name. I find that when I use my real name, people don’t tell me the honest truth vis-à-vis their feelings about my compositions. But when they believe somebody else wrote the piece, their praise (or criticism) tends to be more sincere.

Quick Thoughts

    What does this mean? “Pre-Urbanite”
    One of the things informed critics have frequently praised vis-à-vis the Saint Jean de Brébeuf Hymnal has to do with its careful treatment of the ancient hymns vs. the “Urbanite” hymns. This topic I had believed to be fairly well understood—but I was wrong. The reason I thought people knew about it is simple; in the EDITIO VATICANA 1908 Graduale Romanum (as well as the 1913 Liber Antiphonarius) both versions are provided, right next to each other. You can see what I mean by examining this PDF file from the Roman Gradual of 1908. Most people still don’t understand that the Urbanite versions were never adopted by any priests or monks who sang the Divine Office each day. Switching would have required a massive amount of effort and money, because all the books would need to be changed.

    PDF Download • “Santo Santo Santo”
    Those searching for a dignified, brief, simple, bright setting of SANCTUS in Spanish (“Santo Santo Santo”) are invited to download this Setting in honor of Saint John Brébeuf (organist & vocalist). I wonder if there would be any interest in me recording a rehearsal video for this piece.

Random Quote

“From the responses received, it is thus clear that by far the greater number of bishops feel that the present discipline [Communion on the tongue and not in the hand] should not be changed at all—indeed, that if it were changed, this would be offensive to the sensibility and spiritual appreciation of these bishops and of most of the faithful.”

— Sacred Congregation for Divine Worship (29 May 1969)
