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.”

Released • Jeff Ostrowski’s Seminar: “Secrets of the Conscientious Choirmaster” (9+ hours)

Corpus Christi Watershed · January 10, 2024

NOWLEDGE IS POWER—at least for the conscientious choirmaster! By popular demand, Jeff Ostrowski has spent six months creating a video seminar based upon innumerable lectures, masterclasses, and tutorials he’s presented over the last decade at the Sacred Music Symposium. Mr. Ostrowski, an organist and choirmaster, was already internationally-known as a composer before the age of thirty. He founded—and still organizes—the annual SACRED MUSIC SYMPOSIUM in Los Angeles. You’re cordially invited to read the glowing reviews by participants of this event, more than a hundred of which have been posted on its website. (They were submitted by choir directors across the globe.) To those who assisted him, Mr. Ostrowski wrote this note.

Examples
Jeff’s Volunteer Choir

Jeff Ostrowski selected all his singers from among the congregation. In other words, 100% of the singers he directs came from families in his parish. His choirs contain zero “outside” singers, zero non-Catholics, and zero paid singers. Many members had never sung—in any choir—before he recruited them to sing at Mass.

*  Example • “Veni Creator Spiritus” (sung in English)
—Live recording by Jeff’s volunteer choir.

*  Example • “O Sola Magnarum Urbium” (females only)
—They had never rehearsed this piece before singing it!

*  Example • “Songs Of Thankfulness And Praise” (In Epiphania Domini)
—Live recording by Jeff’s volunteer choir.

*  Example • Pange Lingua Gloriosi (English Translation)
—Studio recording by members of Jeff’s volunteer choir.

    Music List • (Easter Sunday, 2026)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for Easter Sunday—a.k.a. “Ad Missam in die Paschae”—which is 5 April 2026. Please feel free to download it as a PDF file if such a thing interests you. The Fauxbourdon for Communion is particularly moving.
    —Jeff Ostrowski
    PDF Download • “Sprinkling Rite”
    Liturgical reformers who gained power after Vatican II frequently caused great suffering to musicians. With the stroke of a pen, they sometimes make changes that would require thousands—or even millions—of man hours (work undertaken by composers and editors). The Sprinkling Rite during Eastertide is but one tiny example. The version given in that PDF document was the original melody for Roman Missal, Third Edition. Some still prefer that version. However, at the last moment, an “unknown hand” tinkered with a few notes in the antiphon. Those who examine the current edition can verify this with their own eyes.

    ‘Sarum’ Good Friday?
    Plainsong of the Roman Rite has many variants—i.e. slight ‘variations’ or ‘alterations’ made to the ancient melodies. Variants often thrive in particular religious orders. Likewise, before Henry VIII broke away from the Catholic Church, Gregorian Chant variants were frequently associated with individual cathedrals in England: Hereford, Lincoln, Salisbury, and so forth. In the early 20th century, the (Anglican) organist at Westminster Abbey married “Let All Mortal Flesh Keep Silence” to this beautiful variant melody from England. Those who sing Gregorian Chant on Good Friday will recognize the melody. What do you think of this pairing?

Quick Thoughts

    “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!

    PDF Download • “Ubi Caritas” (SATB)
    I remember singing “Ubi Cáritas” by Maurice Duruflé at the conservatory. I was deeply moved by it. However, some feel Duruflé’s version isn’t suitable for small choirs since it’s written for 6 voices and the bass tessitura is quite low. That’s why I was absolutely thrilled to discover this “Ubi cáritas” (SATB) for smaller choirs by Énemond Moreau, who studied with OSCAR DEPUYDT (d. 1925), an orphan who became a towering figure of Catholic music. Depuydt’s students include: Flor Peeters (d. 1986); Monsignor Jules Van Nuffel (d. 1953); Arthur Meulemans (d. 1966); Monsignor Jules Vyverman (d. 1989); and Gustaaf Nees (d. 1965). Rehearsal videos for each individual voice await you at #19705. When I came across the astonishing English translation for “Ubi Cáritas” by Monsignor Ronald Knox—matching the Latin’s meter—I decided to add those lyrics as an option (for churches which have banned Latin). My wife and I made this recording to give you some idea how it sounds.

    PDF Download • “Holy, Holy, Holy”
    For vigil Masses on Saturday (a.k.a. “anticipated” Masses) we use this simpler setting of the “Holy, Holy, Holy” by Monsignor Jules Vyverman (d. 1989), a Belgian priest, organist, composer, and music educator who ultimately succeeded another ‘Jules’ (CANON JULES VAN NUFFEL) as director of the Lemmensinstituut in Belgium. Although I could be wrong, my understanding is that the LEMMENSINSTITUUT eventually merged with “Catholic University of Leuven” (originally founded in 1425). That’s the university Fulton J. Sheen attended.

Random Quote

The Second Plenary Council of Baltimore (Tit. VI, Cap. iii, 379) did order that Vespers be sung, and in their entirety, in all churches on Sundays and feast days and that Vespers be not omitted on account of other services. However, the Fathers of the Council inserted the clause, “quatenus fieri potest,” in consideration of practical difficulties in the carrying out of the decree.
