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.”

31 December 2020 • “COMITES CHRISTI”

The feasts for Saint Stephen Proto-Martyr (26 December), Saint John the Evangelist The Disciple Whom Jesus Loved (27 December), and the Feast of the Holy Innocents (28 December) seem untouched by any liturgical reforms. These are very powerful feasts—I believe they once possessed octaves—and I believe they could sometimes “overpower” a Sunday feast. The rules […]

23 December 2020 • A 5th? or 4th?

I have noticed that where the Editio Vaticana has a descending perfect fourth for the Gradual of Christmas Midnight Mass, many ancient manuscripts have a descending perfect fifth, which is pretty cool: Example A — Example B. The Vatican Edition is a CENTO, and never made any claim to be anything other than a CENTO. […]

“Martinelli’s Letter” (dated 18 February 1910)

My recent post on the repercussion has induced some to ask: “Can we just sing whatever rhythm we want for the Vatican Edition? What about mensuralism? What about Bonvin and Vollaerts?” For those of us who work in the Extraordinary Form, we must follow the rhythm of the Editio Vaticana, and this was addressed in […]

9 December 2020 • A Cool Tradition

Before the reforms of the “Code of Rubrics” (1961), antiphons at Vespers were abbreviated in a cool way. For example, look at this antiphon, Ecce Veniet (from Vespers on the 4th Sunday of Advent). But that tradition—as far as I know—ended in 1961, with §191 which said: “The whole antiphon is always said before and […]

30 November 2020 • “Case in point”

The Solesmes rhythmic markings, which often contradict the official rhythm, do such damage to the antiphons of the Divine Office that—in my humble opinion—they should be abandoned. (In reality, this will never happen.) But sometimes, they do great damage to the melody of the Graduale Romanum, and I would offer the Offertory for the 1st […]

27 November 2020 • ACCENTS

Certain Latin words are constantly mispronounced. For example, Carl Orff’s Carmina Burana is supposed to be pronounced “Cármina” but people frequently pronounce it as “Carmína”—wrong! Another example: Nova organi harmonia is supposed to be pronounced “órgani” but many people erroneously say “orgáni.” A somewhat tricky word is incipit. In Latin, it would be “íncipit” while […]

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.”

18 November 2020 • FEEDBACK

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.”

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 […]

PDF Download • Vespers for the Dead

Mr. Albert Bloomfield kindly sent me “Vespers for the Dead”—which does not fulfill a priest’s obligation to pray the Divine Office, yet is often prayed when a loved one dies. Here is formatting A, and here it is again with formatting B.

20 October 2020 • “What we can’t share”

Almighty God has given to us the example of the Jesuit Martyrs of North America, whose feast day we celebrated yesterday. Of course, along with those eight martyrs we honor their associates, e.g Father François Bressani. I can’t share with you the torments Father Bressani underwent at the hands of Iroquois: it is too brutal. […]

    Music List • (5th Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 5th Sunday of Lent (22 March 2026). If such a thing interests you, feel free to download it as a PDF file. Traditionally, this Sunday was called ‘Passion’ Sunday. Starting in 1956, certain church leaders attempted rename both ‘Passion’ Sunday and ‘Palm’ Sunday—but it didn’t work. For example, Monsignor Frederick McManus tried to get people to call PALM SUNDAY “Second Passion Sunday”—but the faithful rejected that. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

    Music List • (Holy Thursday, 2026)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for Holy Thursday, which is 2 April 2026. If such a thing interests you, feel free to download it as a PDF file. I’m not sure I’ve ever heard a more piercingly beautiful INTROIT, and I have come to absolutely love the SATB version of ‘Ubi cáritas’ we are singing (joined by our burgeoning children’s choir). I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.
    —Jeff Ostrowski
    “O Escam Viatorum” • (Holy Thursday)
    When I was very young, I erroneously believed the four psalms provided by the 1957 Liber Usualis—for Communion on Holy Thursday—were the “correct” music to sing on that first day of the TRIDUUM SACRUM. Those four psalms are: Psalm 22 (Dóminus regit me et nihil mihi déerit); Psalm 71 (Deus judícium tuum regi da); Psalm 103 (Bénedic ánima méa); and Psalm 150 (Laudáte Dóminum in sanctis ejus). It turns out I was way out in left field! While nothing forbids singing those psalms, many other options are equally valid. Our volunteer parish choir will sing this COMMUNION PIECE (joined by our burgeoning children’s choir) on Holy Thursday during Holy Communion. Needless to say, this will happen after the proper antiphon from the GRADUALE ROMANUM has been sung.

Quick Thoughts

    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.
    —Jeff Ostrowski
    Stumped by “Episcopalian Hymnal” (1910)
    Some consider Songs of Syon (1910) the greatest Episcopalian hymnal ever printed. As a Roman Catholic, I have no right to weigh in one way or the other. However, this particular page has me stumped. I just know I’ve heard that tune somewhere! If you can help, please email me. I’m talking about the text which begins: “This is the day the Lord hath made; In unbeclouded light array’d.” The book is by George Ratcliffe Woodward, and its complete title is: Songs of Syon: A Collection of Psalms, Hymns, and Spiritual Songs. Back in 2016, Corpus Christi Watershed scanned and uploaded this insanely rare book. For years our website was the sole place one could download it as a PDF file.
    —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.
