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.”

Does Polyphony “Fit” Ordinary Form Masses?

Jeff Ostrowski · July 11, 2017

URING THE SACRED MUSIC SYMPOSIUM, I described how to painlessly add polyphony to the Ordinary Form by “sneaking it in” with choral extensions. So much information was shared during our conference—from 7:30am until 9:30pm each day, literally—that I wasn’t able to spend sufficient time explaining.

Therefore, I’ve created this video:

REHEARSAL VIDEOS for each individual voice await you at #4884.
As always, the PDF score can be downloaded there, too.


If you desire an Mp3 version of this video, click here.


IF YOU DON’T HAVE enough voices to do the example above, consider the following: Guerrero “Iste Sanctus” (#5294); Palestrina Short (#6482); Palestrina Longer (#6995); Guerrero “Beata Mater” (#3347, #3661, #3579); Durieux (#4638); Palestrina “Impleta sunt” (#5053, #5054); Brudieu (#4327).

The Mass setting in the video is from Victoria’s Officium Defunctorum. This is a famous piece, and I was too scared to “vandalize it” by transposing it up a whole step—but my choir will most likely do so. Fr. Victoria’s work is based on the Requiem KYRIE, so I could have chosen the plainsong accordingly, but only if we were singing it for an actual Requiem. Despite what some assert, these are not rigid rules that can’t be changed. For example, most editors choose Mode II for Allegri’s Miserere Mei, but the actual music is based on the Tonus Peregrinus. Indeed, Sanctus VIII was taken verbatim from O Quam Suavis Est; but does that mean Sanctus VIII can only be sung on feasts where that Antiphon is employed? I think not.

I recorded all the voices for the above video except the third section, which was recorded by volunteers at Sacred Music Symposium 2017. Can you hear the difference? Listen closely to the richness in the third section, which begins at the 2:17 marker.

Don’t expect the congregation to understand immediately when they are supposed to sing. It will take at least a year before they begin to understand. At the Symposium, we spoke of the importance of using the same structure every Sunday for a long time before the good fruits become evident. That is why I would never dream of introducing the propers at OF Masses unless the congregation had a book such as the Isaac Jogues Pew Lectionary, which has 100% of the propers in Latin and English. I repeat: it takes years to reintroduce authentic liturgy, because our people have been robbed for half a century.

    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.

    “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.

    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.

    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

“Now we are aware of the fact that during recent years some artists, gravely offending against Christian piety, have dared to bring into churches works devoid of any religious inspiration and completely at variance with the right rules of art.”

— Ven. Pope Pius XII (25 December 1955)
