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.

    PDF Download • Communion for Sunday
    The COMMUNION ANTIPHON with fauxbourdon psalm verses for this coming Sunday (3 May 2026) is elegant and poignant. It’s such a shame it only comes every three years. This piece—along with all the musical scores for this coming Sunday, which is the 5th Sunday of Easter (Year A)—can be downloaded free of charge from the flourishing feasts website. By the way, how is it already 2026?
    —Jeff Ostrowski
    Season’s End Repertoire
    Looking at the REPERTOIRE SHEET until the end of the choral season, I see that I’ve fallen behind schedule. (The last three months have been extraordinarily busy.) As you know, I have been providing organ harmonies for all the ENTRANCE CHANTS—as well as rehearsal videos—and you can see I’m behind where I planned to be. Now I must make up lost ground. However, the choir picks up the ENTRANCE CHANT with ease, so I’m sure it will all work out. My ‘unofficial’ harmonizations are being posted each week at the flourishing feasts website.
    —Jeff Ostrowski
    PDF Download • “Funeral Procession”
    From a mediæval Book of Hours, I was sent this glorious depiction of a Roman Catholic funeral procession by Simon Bening (d. 1561). The image resolution is extremely high. I’m not sure I know of a more beautiful illustration of a mediæval church. And I love how the servers are wearing red and pink cassocks!

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!
    —Jeff Ostrowski

Random Quote

“Since the English is not meant to be sung, but only to tell people who do not understand Latin what the text means, a simple paraphrase in prose is sufficient. The versions are not always very literal. Literal translations from Latin hymns would often look odd in English. I have tried to give in a readable, generally rhythmic form the real meaning of the text.”

— Fr. Adrian Fortescue (1913)
