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 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.

President’s Corner

    Liturgical Round (“Canon”) in C-Major
    Those who direct children’s choirs are always on the lookout for repertoire that’s dignified, inspired, and pleasing—yet still within reach of young choristers. Such directors will want to investigate this haunting liturgical round (PDF download) which has been married to the KYRIE from Mass VI (EDITIO VATICANA). I have provided an accompaniment, but it’s only for use during rehearsal; i.e. when teaching this round to your choristers. I also provided an organ accompaniment for the KYRIE—which some know by its trope (Kyrie Rex Genitor)—so that your congregation can take part when this round is used as a choral extension during Mass.

    Latin Liturgy Association
    We note with pleasure that Mrs. Regina Morris, president of the Latin Liturgy Association, has featured—on page 4 of Volume CXXIX of their official newsletter—the three (3) terrific versions of the Stations of the Cross found in the Brébeuf Hymnal. One of the main authors for the blog of the Church Music Association of America said (6/10/2019) about this pew book: “It is such a fantastic hymnal that it deserves to be in the pews of every Catholic church.”

Quick Thoughts

    New Bulletin Article • “12 October 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 12 October 2025) talks about an ‘irony’ or ‘paradox’ regarding the 1960s switch to a wider use (amplior locus) of vernacular in the liturgy.

    “American Catholic Hymnal” (1991)
    The American Catholic Hymnal, with IMPRIMATUR granted (25 April 1991) by the Archdiocese of Chicago, is like a compendium of every horrible idea from the 1980s. Imagine being forced to stand all through Communion (even afterwards) when those self-same ‘enlightened’ liturgists moved the SEQUENCE before the Alleluia to make sure congregations wouldn’t have to stand during it. (Even worse, everything about the SEQUENCE—including its name—means it should follow the Alleluia.) And imagine endlessly repeating “Alleluia” during Holy Communion at every single Mass. It was all part of an effort to convince people that Holy Communion was historically a procession (which it wasn’t).

    “Canonic” • Ralph Vaughan Williams
    Fifty years ago, Dr. Theodore Marier made available this clever arrangement (PDF) of “Come down, O love divine” by P. R. Dietterich. The melody was composed in 1906 by Ralph Vaughan Williams (d. 1958) and named in honor of of his birthplace: DOWN AMPNEY. The arrangement isn’t a strict canon, but it does remind one of a canon since the pipe organ employs “points of imitation.” The melody and text are #709 in the Brébeuf Catholic Hymnal.

Random Quote

“I ask that future priests, from their time in the seminary, receive the preparation needed to understand and to celebrate Mass in Latin, and also to use Latin texts and execute Gregorian chant; nor should we forget that the faithful can be taught to recite the more common prayers in Latin, and also to sing parts of the liturgy to Gregorian chant.”
