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.”

PDF Download • Organ Interludes Based on Plainsong (Manuals Only) — 104 pages!

Andrea Leal · August 15, 2022

XCITING NEWS! Mr. Stephen Perez is offering a terrific collection of modal organ interludes as a free PDF download. Many of these interludes are based on the most beloved Gregorian chant melodies: Pange Lingua, Ave Maris Stella, Lauda Sion, Puer Natus, Creator Alme Siderum, Ave Maria, Vidi Aquam, Vexilla Regis, Veni Creator Spiritus, Assumpta Est Maria, and so forth. The selections were chosen with great care, including marvelous composers such as Flor Peeters, Dom Gregory Murray, Dom Alphege Shebbeare, John Lee, Oreste Ravanello, J.S. Bach, and many others. Best of all, these interludes are within reach of the ‘average’ organist, since they are for manuals only.

Dom Gregory Murray’s pieces are particularly beautiful. My parish is currently without an organist, since the person who had been serving as our organist recently entered the seminary. I asked my colleague, Jeff Ostrowski, to record a few of the Murray interludes, so readers can get an idea what they sound like. Mr. Ostrowski chose to record INTERLUDE 37—based on Sanctus VIII—as well as INTERLUDE 59.

    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.)
    —Jeff Ostrowski
    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.
    —Jeff Ostrowski
    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.”
    —Jeff Ostrowski

Random Quote

“Gloria, Credo, etc., may not be broken into detached fragments; it is wrong to omit or hurry over the Proper of the day; it is not permitted to substitute organ playing for the Proper; it is wrong to use, however briefly, themes from theatrical or dance music, from popular songs, love-songs, comic songs; drums, cymbals, piano, bag-pipes are too noisy for Church use .”

— Pope Leo XIII (25 September 1884))
