Jesus said to them: “I have come into this world so that a sentence may fall upon it, that those who are blind should see, and those who see should become blind. If you were blind, you would not be guilty. It is because you protest, ‘We can see clearly,’ that you cannot be rid of your guilt.”

Views from the Choir Loft

“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

    “Common” Responsorial Psalm?
    I try to avoid arguing about liturgical legislation (even with Catholic priests) because it seems like many folks hold certain views—and nothing will ever persuade them to believe differently. You can show them 100 church documents, but it matters not. They won’t budge. Sometimes I’m confronted by people who insist that “there’s no such thing” as a COMMON RESPONSORIAL PSALM. When that happens, I show them a copy of the official legislation in Latin. I have occasionally prevailed by means of this method.

    “Music List” • 5th Sunday of Easter (Year C)
    Some have expressed interest in perusing the ORDER OF MUSIC I prepared for the 5th Sunday of Easter (18 May 2025). If such a thing interests you, feel free to download it as a PDF file. The Communion Antiphon was ‘restored’ the 1970 Missale Romanum (a.k.a. MISSALE RECENS) from an obscure martyr’s feast. Our choir is on break this Sunday, so the selections are relatively simple in nature.
    —Jeff Ostrowski
    Communion Chant (5th Sunday of Easter)
    This coming Sunday—18 May 2025—is the 5th Sunday of Easter, Year C (MISSALE RECENS). The COMMUNION ANTIPHON “Ego Sum Vitis Vera” assigned by the Church is rather interesting, because it comes from a rare martyr’s feast: viz. Saint Vitalis of Milan. It was never part of the EDITIO VATICANA, which is the still the Church’s official edition. As a result, the musical notation had to be printed in the Ordo Cantus Missae, which appeared in 1970.

Quick Thoughts

    Antiphons Don’t Match?
    A reader wants to know why the Entrance and Communion antiphons in certain publications deviate from what’s prescribed by the GRADUALE ROMANUM published after Vatican II. Click here to read our answer. The short answer is: the Adalbert Propers were never intended to be sung. They were intended for private Masses only (or Masses without music). The “Graduale Parvum,” published by the John Henry Newman Institute of Liturgical Music in 2023, mostly uses the Adalbert Propers—but sometimes uses the GRADUALE text: e.g. Solemnity of Saints Peter and Paul (29 June).

    When to Sit, Stand and Kneel like it’s 1962
    There are lots of different guides to postures for Mass, but I couldn’t find one which matched our local Latin Mass, so I made this one: sit-stand-kneel-crop
    —Veronica Brandt
    The Funeral Rites of the Graduale Romanum
    Lately I have been paging through the 1974 Graduale Romanum (see p. 678 ff.) and have been fascinated by the funeral rites found therein, especially the simply-beautiful Psalmody that is appointed for all the different occasions before and after the funeral Mass: at the vigil/wake, at the house of the deceased, processing to the church, at the church, processing to the cemetery, and at the cemetery. Would that this “stational Psalmody” of the Novus Ordo funeral rites saw wider usage! If you or anyone you know have ever used it, please do let me know.
    —Daniel Tucker

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)
