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.”

20 November 2020 • Epiphany Sequence?

A very interesting Missale from 1759AD has a Sequence for the Epiphany, but I don’t know where one could find the musical notation. The Seqence is called: “Prompto Gentes Animo Ferte Nunc Altissimo Honorem Et Gloriam.”

From a priest in the Midwest: “That video by Andrea Leal which explains hymn meters and hymn text exchange is informative and a truly great explanation. Thank you for sending it to me. I hope all is well with you. God bless you as we soon enter into Advent.”

“Alma Redemptoris Mater” • Thirteen (13) Organ Accompaniments

When it comes to Gregorian harmonizations, this piece is surely the “pons asinorum.”

16 November 2020 • Exciting addition!

By kind permission of the Trustees of the London Oratory, we have added Mæstro Patrick Russill’s outstanding organ accompaniment for “Salve Regina” to the other versions currently available for free PDF download. Patrick Russill needs no introduction among church musicians the world over, and many consider his harmonization the finest of all.

6 November 2020 • FEEDBACK

The director of music at EWTN wrote to us about the Brébeuf hymnal: “I do believe your hymnal has the best harmonizations available. We have used several of your harmonizations on EWTN. I have recommended to other hymnal editors that they get aligned with Corpus Christi Watershed to improve their harmonizations. Take care.”

Msgr. Schmitt backs up Rev. Fortescue

My colleague, Andrea Leal, recently posted something extraordinary: an English translation of a NOTITIAE document from 1970 which explains why the reformers did such violence to the ancient Proprium Missæ. The author of that document erroneously claims that Gregorian composers changed the wording for musical purposes, but the real reason Missal and Gradual don’t always […]

“Polyphonic Credo” during Communion?

It sounds strange to Americans, but a very common European tradition is to sing a polyphonic “Agnus Dei” during the distribution of Holy Communion, famously defended by Cardinal Ratzinger in 1995. Monsignor Francis P. Schmitt wrote about visiting Saint Joseph Oratory in Montreal, and says: “A polyphonic Creed was sung during the distribution of Communion.” […]

The Best We’ve Done?

Perhaps the most significant item we’ve yet had the honor of producing is an English translation of an extremely rare document from 1970. A member of the Consilium—Father Adalbert Franquesa Garrós—explains why the reformers felt it necessary to destroy most of the ancient Mass propers. In particular, this reformer priest claims that unless verses of […]

President’s Corner

    Good Friday Flowers
    Good Friday has a series of prayers for various parties: the pope, catechumens, pagans, heretics, schismatics, and so forth. In the old liturgical books, there was no official ‘name’ for these prayers. (This wasn’t unusual as ‘headers’ and ‘titles’ for each section is a rather modern idea.) The Missal simply instructed the priest to go to the Epistle side and begin. In the SHERBORNE MISSAL, each prayer begins with a different—utterly spectacular—flower. This PDF file shows the first few prayers. Has anyone counted the ‘initial’ drop-cap flowers in the SHERBORNE MISSAL? Surely there are more than 1,000.

    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.

    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

    “Dies Irae” • A Monstrous Translation
    It isn’t easy to determine what Alice King MacGilton hoped to accomplish with her very popular book—A Study of Latin Hymns (1918)—which continued to be reprinted in new editions for at least 34 years. This PDF file shows her attempt to translate the DIES IRAE “in the fewest words possible.” There’s a place for dynamic equivalency, but this is repugnant. In particular, look what she does to “Quærens me sedísti lassus.”
    —Jeff Ostrowski
    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.
    —Jeff Ostrowski
    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.

Random Quote

Don Fernando de las Infantas wrote to the Pope, trying to get him to stop Palestrina from corrupting all the plainsong editions: “The errors which certain musicians, in all good faith, think they have found in plainchant are not errors at all, but on the contrary contain some of the most beautiful musical passages ever written.”

— Don Fernando de las Infantas (1578 A.D.)
