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.

    Music List • (3rd Sund. Ordinary Time)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for this coming Sunday: the 3rd Sunday in Ordinary Time (Year A). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the monumental feasts website alongside the official texts in Latin.

    “Holy Name Hymn” (2-Voice Arrangement)
    When we post a direct URL link, we frequently get thousands of downloads. But when scrolling is required, very few take the time. I mention this because those who click on this URL link and scroll to the bottom can download—completely free of charge—a clever 2-voice arrangement for a famous hymn to the Most Holy Name of Jesus. In a pinch, it can be nicely sung by one male and one female! It will be of interest to those who seek arrangements for two voices.

    PDF Download • Introit (3rd Sn. Ord.)
    This coming Sunday, 25 January 2026, is the 3rd Sunday in Ordinary Time (Year A). The ENTRANCE CHANT (“Dóminus secus mare”) is somewhat rare because it comes from the New Testament. The authentic version in Latin—of astounding antiquity—was jettisoned in 1955 but restored in 1970. This rehearsal video has me attempting to sing the melody while simultaneously accompanying myself on the organ. I encourage you to print off the organ accompaniment (PDF) and play through it because it has extremely ‘happy’ harmonies.

    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.
    —Jeff Ostrowski
    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.
