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.”

Your Christmas Present!

Jeff Ostrowski · December 24, 2017

90902 CCW present E RECENTLY launched a special fundraising drive, and promised to release certain items if we met our goal. Thanks to your generosity, we succeeded; so below are the files we promised. Of course the money is important—because it allows us to survive—but on a level you might not realize, the fundraising also gives encouragement. It demonstrates that our efforts matter enough to readers that they’ll donate (and church musicians are not wealthy). We enjoyed reading the little “notes” you sent in with your pledges, even the electronic ones.

When our contributors get discouraged, I always say the same thing: “Remember we are trying to do something positive. This is not easy; and the proof is how few Catholic websites are positive vs. how many Catholic websites consist of negativity, gossip, and scandal.”

Merry Christmas!

    Music List • “5th Sunday of Easter” (Year A)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for the 5th Sunday of Easter Sunday—a.k.a. “Dominica V Paschae”—which is 3 May 2026. Please feel free to download it as a PDF file if such a thing interests you. The COMMUNION (“Tanto Témpore Vobíscum Sum”) is rather somber, with awesome fauxbourdon psalm verses. The ENTRANCE CHANT is bright and happy.

    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?

    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.

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!

Random Quote

“The chapter decides that henceforth neither singers nor instrumentalists may be loaned to any outside individual or organization, any more than can the chalices or copes owned by the cathedral. This prohibition applies to all those days of the church calendar for which polyphony is designated.” [From “The Life of Father Francisco Guerrero.”]
