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.”

President’s Corner

    PDF Download • “Eb Organ Postlude”
    Gustav Adolf Merkel (d. 1885) was a German organist, teacher, and composer. Although a Lutheran himself, he held the appointment at the (Roman Catholic) Cathedral of Dresden from 1864 until his death. You can download his Organ Postlude in E-Flat, which I like very much. He has an interesting way of marking the pedal notes. What do you think?
    —Jeff Ostrowski
    Music List • (Palm Sunday, 2026)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for Palm Sunday—a.k.a. “Dominica in palmis de Passione Domini”—which is 29 March 2026. Please feel free to download it as a PDF file if such a thing interests you. The OFFERTORY (Impropérium exspectávit cor meum) is quite moving. Even though the COMMUNION ANTIPHON is relatively simple, the Fauxbourdon makes it sound outstanding.
    —Jeff Ostrowski
    Easter • Would You Sing This Hymn?
    He who examines Laudes Dei: a hymnal for Catholic congregations (St. Louis, 1894) will discover this pairing of a hymn for Easter. For the record, this isn’t the only Catholic hymn book to marry that text and melody; e.g. Saint Mark’s Hymnal for Use in the Roman Catholic Church in the United States (Peoria, 1910) does the same thing. Sometimes an unexpected pairing—chosen with sensitivity—can be superb, forcing singers to experience the text in a ‘fresh’ and wonderful way. On the other hand, we sometimes encounter something I’ve called “PERNICIOUS HYMN PAIRINGS.” If you find the subject in intriguing, feel free to peruse an article I published in May of 2023. As always, my email inbox is open if you have a bone to pick with my take.

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 Vatican Council has not been treated as a part of the entire living Tradition of the Church, but as an end of Tradition, a new start from zero. The truth is that this particular council defined no dogma at all, and deliberately chose to remain on a modest level, as a merely pastoral council; and yet many treat it as though it had made itself into a sort of superdogma which takes away the importance of all the rest.”

— Cardinal Ratzinger (speaking formally as head of the CDF)
