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.”

Jeff Ostrowski · January 4, 2023

RISONERS AT ALCATRAZ were sometimes consigned to “THE HOLE,” and could remain alone (in total darkness) for nineteen days. One prisoner later recounted his method of keeping his sanity: “What I used to do is, I’d tear a button off my coveralls, flip it up in the air, then I’d turn around in circles, and I’d get down on my hands and knees to hunt for that button. When I found the button, I’d stand up and do it again.” This went on hour after hour, day after day, week after week. Why do I bring this up? Well, I certainly realize a choirmaster’s vocation can be difficult, with many obstacles to overcome. Yet, we should remember the many blessings we’ve received from God. Indeed, millions of people would gladly exchange their heavy crosses—such as extreme poverty, oppression, disabilities, and illness—for the (relatively) light crosses Jesus has placed on our shoulders. That doesn’t mean we should go looking for trouble. On the contrary, we should steal every good idea we can from excellent choirmasters. Today, I will present two ‘tricks’ I consider crucial.

Crucial Technique #1 • Needless to say, not everyone has spent years in a conservatory studying music theory. Nevertheless, one of the crucial ‘tricks’ when it comes to directing choirs is to select excellent harmonizations. Avoid harmonizations which are dull, stagnant, uninspired, repetitive, and utilize poor voice-leading. Currently, the best collection—and the most plentiful source—of hymn harmonizations is the Brébeuf Catholic Hymnal. The harmonies are beautiful, the voice-leading is pristine, and the vocal ranges are are comfortable.

The Spice Of Life • What is the “spice” of life? Variety is the spice of life. The Brébeuf Hymnal embraces multifarious harmonic approaches. Indeed, it even contains harmonizations for plainsong! Good harmonies often “go somewhere”—i.e. they have a structure which is interesting for the ear. Consider the following harmonization of Véni Creátor Spíritus. The SOPRANO (broadly speaking) ascends; therefore, the BASS descends in perfect stepwise motion, more than an octave:

Needless to say, the Brébeuf Hymnal did not “invent” this principle. For instance, this technique is a mainstay in the harmonizations by the LEMMENSINSTITUUT:

Failure To Explain • I was attempting to explain this to a friend of mine. She said: “Jeff, you should record these harmonies with human voices, to illustrate what you mean.” Therefore, with the help of Corrinne May, we took one of the plainsong harmonizations from the Brébeuf Hymnal and recorded it with human voices. See if you can hear the perfect descending stepwise motion in the BASS, contrasting with the ascending SOPRANO lines:

“Extension” Scores • The musical score posted above is part of the “Brébeuf Extension series.” Basically, those are private scores created for my choir—using harmonies & texts from the Brébeuf Hymnal—sung completely in Latin, not English. I have tons of them ready to be released … but I need to figure out a way to post these online. My friends (Veronica Brandt, Matthew Frederes, and James Doherty) are helping me with this, because I’m no good with computers.

Crucial Technique #2 • I promised to give away two choirmaster ‘tricks’ in this article. The second is this: Always be flexible. Prepare a PLAN B … and a PLAN C and PLAN D. For example, last Sunday we had nineteen (19) choir members missing, due to illness and holiday travel. Therefore, instead of doing a polyphonic KYRIE, I asked the choir to pull out KYRIE II from the Père Daniel Kyriale. Here’s how that sounded:

A directive issued under Pope Pius XII says: “In general it is better to do something well on a small scale than to attempt something elaborate without sufficient resources to do it properly” (De Musica Sacra, 3 September 1958, §60a). The arrangement above—Corde Natus Ex Parentis—should only be attempted by singers who have good pitch and a certain musical “sensitivity.” In my view, amateurs should not attempt it unless they are willing to invest considerable rehearsal time. PLAINSONG, on the other hand, is usually less demanding—and it’s an excellent way to get amateurs singing … and listening to each other!

    “Reminder” — Month of April (2026)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. It couldn’t be easier to subscribe! Just scroll to the bottom of any blog article and enter your email address.

    Simplified Accompaniment (Easter Hymn)
    Number 36 in the Brébeuf Hymnal is “At the Lamb’s high feast we sing,” an English translation for Ad Cenam Agni Próvidi (which was called “Ad Régias Agni Dapes” starting 1631). As of this morning, you can download a simplified keyboard accompaniment for it. Simply click here and scroll to the bottom. Many organists are forced to serve simultaneously as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult—which explains why choirmasters appreciate these simplified keyboard accompaniments. Sadly, many readers will click that link but forget to scroll to the bottom where the simplified PDF file is located.

    PDF Download • “Quasi Modo Sunday”
    The Introit for “Quasi Modo Sunday” (12 April 2026) is particularly beautiful. The musical score can be downloaded as a PDF file, and so can the organ accompaniment. The official language of the Catholic Church is Latin (whereas Greek is our mother tongue). Vatican II said Gregorian Chant must be given “first place” under normal circumstances. As a result, some parishes will rightly sing the authentic version. On the other hand, because so many USA dioceses disobey the mandate of Vatican II, some musicians sing plainsong in the vernacular. I have attempted to simultaneously accompany myself on the pipe organ while singing the English version. Although very few take advantage of it, the complete Proprium Missae is posted at the flourishing feasts website.

Quick Thoughts

    PDF Download • “Anima Christi”
    I received a request for an organ accompaniment I created way back in 2007 for the “Anima Christi” Gregorian Chant. You can download this PDF file which has the score in plainsong followed by a keyboard accompaniment. Many melodies have been paired with “Anima Christi” over the centuries, but this is—perhaps—the most common one.

    PDF • “Liturgical Law” (467 Pages)
    On Good Friday during the middle ages, the pope privately recited THE ENTIRE PSALTER. If you don’t believe me, see for yourself by reading this passage by Dom Charles Augustine Bachofen (d. 1943). His famous book—called “Liturgical Law: A Handbook Of The Roman Liturgy”—was published by the Benjamin Herder Book Company, which was the American arm (operating out of St. Louis, Missouri) of one of the world’s most significant Catholic publishers. Dom Charles Augustine Bachofen was born in Switzerland but spent his career between the Benedictine monasteries at Conception (Missouri) and Mount Angel (Oregon). His 1931 masterpiece, Liturgical Law can be downloaded as a PDF file … 467 pages!

    “Gregorian Chant Quiz” • 24 March 2026
    How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!
