PDF Download • Brief Polyphonic “Asperges Me” for SATB by Father Guerrero (d. 1599)

Jeff Ostrowski · September 20, 2022

ORE THAN FIVE YEARS AGO, I decided to stop 1 composing music—and I can still remember the very day it happened. Dr. Calabrese was visiting Los Angeles, conducting the KYRIE from Father Guerrero’s Missa Beata Mater. Hearing that brief piece with only four voices, something powerful struck me. I realized Guerrero was composing “on a different level.” What I heard was the RESULT of a genuine genius—from boyhood immersed in the world’s most powerful music—composing in a way that makes the human voice sound as magnificent as it can in this world.

Physically Present • Recordings don’t count here. Nor do notes on a page. It’s all about being physically present and hearing Father Guerrero’s pristine counterpoint, his manipulation of overtones, his astounding use of imitation, his uncanny control of dissonance & consonance, and his incomparable rhythmic mastery. It required 400 years of musical experimentation all across Europe to produce the polyphonic miracle of Francisco Guerrero. I realized my efforts at composition were akin to demanding that I play alongside Larry Bird, Wilt Chamberlain, and Michael Jordan.

A Tiny Piece • The following is not even a real piece. Rather, it’s a brief excerpt of a very long composition by Father Guerrero. Nevertheless, I find it utterly captivating, and here’s my attempt at recording all the voices myself (to approximate how it sounds):

M Rehearsal videos for each individual voice await you at #47772.

Sadness: Most readers won’t click on the individual voice parts, and that makes me sad. When we post a “scandalous” liturgical video, we get 40,000 views. I wish we could garner as many views for the rehearsal videos because it’s incumbent upon us to revive authentic sacred music!

1 Technically, I have not completely stopped composing, but the small things I do compose—such as Gregorian accompaniments and short antiphons—are not “composing” in the sense of writing large-scale works (such as symphonies). Once in a blue moon, I still compose a larger work, but always under a fake name. I find that when I use my real name, people don’t tell me the honest truth vis-à-vis their feelings about my compositions. But when they believe somebody else wrote the piece, their praise (or criticism) tends to be more sincere.

President’s Corner

    PDF Download • “Polyphonic Extension” (Kevin Allen) for Gloria III
    EVIN ALLEN was commissioned by Sacred Music Symposium 2025 to compose a polyphonic ‘middle section’ for the GLORIA from Mass III, often denoted by its trope name: Missa Kyrie Deus sempiterne. This year, I’m traveling from Singapore to serve on the symposium faculty. I will be conducting Palestrina’s ‘Ave Maria’ as well as teaching plainsong to the men. A few days ago, I was asked to record rehearsal videos for this beautiful polyphonic extension. (See below.) This polyphonic composition fits ‘inside’ GLORIA III. That is, the congregation sings for the beginning and end, but the choir alone adds polyphony to the middle. The easiest way to understand how everything fits together is by examining this congregational insert. You may download the score, generously made available to the whole world—free of charge—by CORPUS CHRISTI WATERSHED:

    Free rehearsal videos for each individual voice await you at #24366. Related News • My colleague, Jeff Ostrowski, composed an organ accompaniment for this same GLORIA a few months ago. Obviously, the organist should drop out when the polyphony is being sung.

    “Booklet of Eucharistic Hymns” (16 pages)
    I was asked to create a booklet for my parish to use during our CORPUS CHRISTI PROCESSION on 22 June 2025. Would you be willing to look over the DRAFT BOOKLET (16 pages) I came up with? I tried to include a variety of hymns: some have a refrain; some are in major, others in minor; some are metered, others are plainsong; some are in Spanish, some are in Latin, but most are in English. Normally, we’d use the Brébeuf Hymnal—but we can’t risk having our congregation carry those heavy books all over the city to various churches.
    —Jeff Ostrowski
    “Yahweh” in church songs?
    My pastor asked me to write a weekly column for our parish bulletin. The one scheduled to run on 22 June 2025 is called “Three Words in a Psalm” and speaks of translating the TETRAGRAMMATON. You can read the article at this column repository. All of them are quite brief because I was asked to keep within a certain word limit.

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

At the Catholic gathering (Katholikentag) held at Breslau in August, the Papal Nuncio celebrated Mass for 80,000 participants, facing the people (the “Missa versus populum”).
