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.

    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.

    Music List • (4th Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 4th Sunday of Lent (15 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has sublime propers. It is most often referred to as “Lætare Sunday” owing to its INTROIT. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

Quick Thoughts

    Stumped by “Episcopalian Hymnal” (1910)
    Some consider Songs of Syon (1910) the greatest Episcopalian hymnal ever printed. As a Roman Catholic, I have no right to weigh in one way or the other. However, this particular page has me stumped. I just know I’ve heard that tune somewhere! If you can help, please email me. I’m talking about the text which begins: “This is the day the Lord hath made; In unbeclouded light array’d.” The book is by George Ratcliffe Woodward, and its complete title is: Songs of Syon: A Collection of Psalms, Hymns, and Spiritual Songs. Back in 2016, Corpus Christi Watershed scanned and uploaded this insanely rare book. For years our website was the sole place one could download it as a PDF file.

    “Dies Irae” • A Monstrous Translation
    It isn’t easy to determine what Alice King MacGilton hoped to accomplish with her very popular book—A Study of Latin Hymns (1918)—which continued to be reprinted in new editions for at least 34 years. This PDF file shows her attempt to translate the DIES IRAE “in the fewest words possible.” There’s a place for dynamic equivalency, but this is repugnant. In particular, look what she does to “Quærens me sedísti lassus.”

    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

“These French offices represent a new case of the old tendency towards local modification—which the Council of Trent had meant to repress. They are commonly attributed to Gallican ideas and are supposed to be not free from Jansenist venom. Some of these local French uses survived almost to our own time. They were supplanted by the Roman books in the 19th century, chiefly by the exertions of Dom Prosper Guéranger (d. 1875).”

— Dr. Adrian Fortescue (d. 1923)
