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.

    PDF • “Music List” (Sunday, 28 December)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for Feast of the Holy Family of Jesus, Mary, & Joseph (28 Dec. 2025). If such a thing interests you, feel free to download it as a PDF file. The FAUXBOURDON verses for the Communion Antiphon are particularly gorgeous. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

    PDF • “Music List” (Xmas Midnight Mass)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for Christmas Midnight Mass (“Ad Missam In Nocte”). If such a thing interests you, feel free to download it as a PDF file. The ENTRANCE CHANT is simple, but quite beautiful. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

    PDF • “Music List” (4th Sunday of Advent)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 21 December 2025, which is the 4th Sunday of Advent (Year A). If such a thing interests you, feel free to download it as a PDF file. The ENTRANCE CHANT is the famous “Roráte Coeli” and the fauxbourdon setting of the COMMUNION is exquisite. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

Quick Thoughts

    PDF Download • “In Paradisum” in English
    We always sing the IN PARADISUM in Latin, as printed on this PDF score. I have an appallingly bad memory (meaning I’d be a horrible witness in court). In any event, it’s been brought to my attention that 15 years ago I created this organ accompaniment for the famous and beautiful ‘IN PARADISUM’ Gregorian chant sung in English according to ‘MR3’ (Roman Missal, Third Edition). If anyone desires such a thing, feel free to download and print. Looking back, I wish I’d brought the TENOR and BASS voices into a unison (on B-Natural) for the word “welcome” on the second line.
    —Jeff Ostrowski
    What does this mean? “Pre-Urbanite”
    Something informed critics have frequently praised vis-à-vis the Saint Jean de Brébeuf Hymnal is 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

“Dom Pothier does not belong to the dim past, as the silence which surrounds his name would lead one to believe. Only a few years separate us from the time when—growing old and heavily burdened by trials—Dom Pothier was concentrating his ever keen attention on the study of manuscripts in the Belgian place of retreat where his community had found refuge. For he was the abbot; and there can be no doubt that the cross he wore during those days was a cross of sorrow, though he bore it with a smile.”

— Dom Ermin Vitry, OSB (31-OCT-1936)
