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.”

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!

President’s Corner

    Which Mass?
    In 1905, when the Vatican Commission on Gregorian Chant began publishing the EDITIO VATICANA—still the Church’s official edition— they assigned different Masses to different types of feasts. However, they were careful to add a note (which began with the words “Qualislibet cantus hujus Ordinarii…”) making clear “chants from one Mass may be used together with those from others.” Sadly, I sometimes worked for TLM priests who weren’t fluent in Latin. As a result, they stubbornly insisted Mass settings were ‘assigned’ to different feasts and seasons (which is false). To understand the great variety, one should examine the 1904 KYRIALE of Dr. Peter Wagner. One should also look through Dom Mocquereau’s Liber Usualis (1904), in which the Masses are all mixed up. For instance, Gloria II in his book ended up being moved to the ‘ad libitum’ appendix in the EDITIO VATICANA.

    PDF Download • “Atténde Dómine”
    Although it isn’t nearly as ancient as other hymns in the plainsong repertoire, Atténde Dómine, et miserére, quía peccávimus tíbi (“Look down, O Lord, and have mercy, for we have sinned against Thee”) has become one of the most popular hymns for LENT—perhaps because it was included in the famous Liber Usualis of Solesmes. This musical score (PDF file) has an incredibly accurate version in English, as well as a nice version in Spanish, and also the original Latin. Although I don’t claim to have a great singing voice, this morning I recorded this rehearsal video.

Quick Thoughts

    Extreme Unction
    Those who search Google for “CCCC MS 079” will discover high resolution images of a medieval Pontificale (“Cambridge, Corpus Christi College, MS 079”). One of the pages contains this absolutely gorgeous depiction of the Sacrament of Extreme Unction.

    PDF Chart • “Plainsong Rhythm”
    I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”

    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.

Random Quote

“Oh, the happy choir director who is hired to start work on a brand new choir, or who walks into his first rehearsal a total stranger to the existing group—what a fortunate man he is! The new choir director who is a former member of the choir, or a member of the congregation, or the nephew of the alto soloist, or a former altar boy, or otherwise well acquainted with the choir, is in for a few headaches.”

— Paul Hume (1956)
