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.”

Choirs Love This Piece!

Back in 2001, I created an arrangement of “O Filii Et Filiae” based on the work of Monsignor Jules Van Nuffel. You can access free rehearsal videos at #5909. Choirs absolutely love singing this piece. You can hear my volunteer choir singing a live recording.

Holy Thursday Introit • “Pure” Vaticana

Many people wonder what Cantus Gregorianus sounds like when sung according to the “official rhythm.” You can hear the Introit for Maundy Thursday sung that way—i.e. according to the “pure” Editio Vaticana—if you click here. Technically, this is the only interpretation allowed by the Church; cf. the letter of Cardinal Martinelli (18 February 1910).

“Ah, Holy Jesus, How Hast Thou Offended?”

A wonderful passiontide hymn is #692 in the Brébeuf hymnal. It works especially well for Communion. Here is a live recording from last Sunday, sung by the fabulous female singers in my volunteer parish choir.

PDF Download • “Palm Sunday Hymn”

During the procession on Palm Sunday, the 1962 rubrics allow alius cantus in honorem Christi Regis—“a hymn or song in honor of Christ the King.” A simple yet beautiful Gregorian hymn you might consider is Te Sæculorum Principem, which was composed for the feast of Christ the King by Father Vittorio Genovesi (d. 1967). The […]

Free Organ Accompaniment • “Vexilla Regis”

During Passiontide, the hymn at Vespers is the mighty Vexilla Regis Prodeunt of Bishop Venantius Fortunatus. In 2015, I composed an organ accompaniment for this hymn with each verse written out. This comes in pretty handy on occasions when the organist must “lead the hymn from the organ bench.” Please feel free to download my […]

President’s Corner

    Music List • (3rd Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 3rd Sunday of Lent (8 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has magnificent propers. Its stern INTROIT (“Óculi mei semper ad Dóminum”) is breathtaking, and the COMMUNION (“Qui bíberit aquam”) with its fauxbourdon verses is wonderful. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.
    —Jeff Ostrowski
    “Samaritánæ” (3rd Sunday of Lent)
    With regard to the COMMUNION for the 3rd Sunday of Lent (Year A), the Ordo Cantus Missae—which was published in 1969 by the Vatican, bearing Hannibal Bugnini’s signature and approbation in its PREFACE—inexplicably introduced a variant melody and slightly different words, as you can see by this comparison chart. When it comes to such items, they’re always done in secrecy by unnamed people. (Although it is known that Dom Eugène Cardine collaborated in the creation of the GRADUALE SIMPLEX, a book considered by some to be a travesty.)

    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.

Quick Thoughts

    Grotesque Pairing • “Passion Chorale”
    One of our rarest releases was undoubtably this PDF scan of the complete Pope Pius XII Hymnal (1959) by Father Joseph Roff, a student of Healey Willan. One of the scarcest titles in existence, this book was provided to us by Mr. Peter Meggison. Back in 2018, we scanned each page and uploaded it to our website, making it freely available to everyone. Readers are probably sick of hearing me say this, but just because we upload something that doesn’t necessarily mean it’s wonderful or worthy of imitation. We upload many publications precisely because they are ‘grotesque’, interesting, or revealing. Whereas the Brébeuf Catholic Hymnal had an editorial board that was careful and sensitive vis-à-vis pairing texts with tunes, the Pope Pius XII Hymnal (1959) seems to have been rather reckless in this regard. Please take a look at what they did with the PASSION CHORALE and see whether you agree.

    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.
    —Corpus Christi Watershed
    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.”

In the United States, Archbishop Kenrick had said in his “Moral Theology” that it was acceptable to sing the “Véni Sáncte Spíritus” before the sermon.
