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 2 of 3

Jeff Ostrowski · May 14, 2021

HE OTHER DAY, I was speaking to my colleague, Keven Smith, a Curtis graduate who currently serves as choirmaster at the FSSP parish in Sacramento, California. I had decided not to record any more rehearsal videos because I’m “self conscious” when it comes to my singing voice. My feelings of inadequacy may have come from studying piano—since pianists are taught from a young age they are never good enough. 1 In any event, Keven basically told me that rehearsal videos don’t have to be perfect. He said they are valuable and I should continue making them—even though I am not pleased with my voice in the Soprano range.

I therefore offer you this rehearsal video and score. (It begins with Soprano and Alto, but at the 0:58 marker, it switches to Tenor and Bass.)

*  PDF Download • “AGNUS DEI FOR TWO VOICES”
—Based on a piece by Father Francisco Guerrero (d. 1599).

That piece is an excellent way to get your people singing when choirs return—because it’s only two voices, the range is not excessive, the Solfège is already added, and it just “clicks” in real life because Guerrero was a master of counterpoint.

Working with Volunteer Choirs:

The worst thing you can do during a choir rehearsal is talk a lot. The people are coming there to sing. And by singing together over and over, they will learn to blend. We have recently (2 weeks ago) been allowed to have choir rehearsals after a year of rehearsals being forbidden. In some ways, it is like starting over for me as a director. I need these choirs to sing together for a long time—and the issues with tuning, breathing, and relaxation will begin to be resolved. Below I am being venturesome. I’m releasing this live recording from our rehearsal in which we begin in unison then attempt to add parts:

Variety is the Spice of Life:

As choirmasters, we can learn from the great artists, who knew that variety was important to concert programs. These days, that notion seems lost. For instance, I once attended a concert by András Schiff in Kansas City, and the entire first half was Scarlatti Sonatas. Now, I love Scarlatti—but this was not an appropriate choice and most of the audience soon began to snore. Therefore, in our rehearsals, we do hard work—such as singing the above Agnus Dei in Solfège—but not for the entire rehearsal. We mix it up! We also sing “fun” songs, such as Brébeuf # 704 Hymn for the Ascension:

We also sing contemporary pieces. Here is an excerpt from last night’s rehearsal:

*  Mp3 Download • Richard Rice Kyrie
—“Mass of the Angels” by Richard Rice is #4781.

I also toss in other types of music, such as medieval plainson with an Ison added:

*  Mp3 Download • Gregorian Chant With Drone
—Listen carefully, and you hear one of the Bass singers hit a low D.

Update (8 June 2021):

You can hear a live recording of our first attempt at singing the Guerrero 2-voice “Agnus Dei.”


NOTES FROM THIS ARTICLE:

1   Piano students know their octaves will never be as fast as Josef Hofmann, their thirds will never be as clean as Josef Lhevinne, their repeated notes will never be as crisp as Horowitz, their legato will never be as sumptuous as Ignaz Tiegerman, and so forth.

    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.

    PDF • Our Lady of Guadalupe (12 Dec.)
    The Responsorial Psalm may be downloaded as a PDF file (organist & vocalist) for 12 December, which is the Feast of Our Lady of Guadalupe. When it comes to the formulary for this Mass, it’s astounding how infrequently it’s included in official books. Prior to Vatican II, one had to search through “supplemental material” printed in the back of hand-missals and graduals. But since 1970, the feast is virtually nonexistent. According to the UNIVERSAL KALENDAR, 12 December is the “Feast of Saint Jane Frances De Chantal, Religious” (Die 12 decembris: S. Ioannæ Franciscæ de Chantal, religiosæ). Why should that feast overpower Our Lady of Guadalupe? In the United States, OLG is celebrated—and I’d assume in Mexico, Central America, South America, and Canada—but, as I said, the Propria Missae are virtually impossible to locate. I possess only three books which mention this feast.

    Simplified Accompaniment (Advent Hymn)
    Many organists are forced to simultaneously serve as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult. I invite you to download this simplified organ accompaniment (PDF) which in the Father Brébeuf Hymnal is hymn #661: “Come, Thou Long-Expected Jesus” (for ADVENT). I’m toying with the idea of creating a whole bunch of these, to help amateur organists. The last one I uploaded was downloaded more than 2,900 times in a matter of hours—so there appears to be interest.

Quick Thoughts

    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.

    Pope Leo XIV on Sacred Music
    On 5 December 2025, Pope Leo XIV made this declaration with regard to liturgical music.

    “Translations Approved for Liturgical Use”
    According to the newsletter for USSCB’s Committee on Divine Worship dated September 1996, there are three (3) translations of the Bible which can be used in the sacred liturgy in the United States. You can read this information with your own eyes. It seems the USCCB and also Rome fully approved the so-called NRSV (“New Revised Standard Version”) on 13 November 1991 and 6 April 1992 but this permission was then withdrawn in 1994.

Random Quote

“I have devoted myself too much, I think, to Bach, to Mozart and to Liszt. I wish now that I could emancipate myself from them. Schumann is no use to me any more, Beethoven only with an effort and strict selection. Chopin has attracted and repelled me all my life; and I have heard his music too often—prostituted, profaned, vulgarized … I do not know what to choose for a new repertory!”

— Ferruccio Busoni (to a colleague in 1922, when he was 56 years old)
