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.”

Jeff Ostrowski · February 26, 2022

EADERS WILL RECALL that I usually introduce polyphony with multiple sections in a “piecemeal” manner. Several examples can be found at this link—but most people find it more convenient to explore LALEMANT POLYPHONIC. There’s no real “mystery” to piecemeal polyphony; it just means introducing a piece slowly, rather than attempting to teach your choir a 3-section KYRIE ELEYSON or a 3-section AGNUS DEI all at once. Today, I introduce part 2 (“Christe”) of a composition by Verdelot. As time goes on, I will add the other sections.

Going Way Back: This music is from a much earlier period (stile antico) than compositions we usually sing. You can really tell it’s different, too! The long vocal lines are different. The musica ficta is different. The harmonic rhythm and tonality are different. The lengths of the notes are different (especially the “unequal” ending notes). And the text underlay! To be honest, I massively modified the text underlay; it was just too different from what my choirs are used to. I wasn’t brave enough to leave it alone! The further you go back in music history, the more difficult the tessitura—but that is not a problem in this particular example. We usually sing Guerrero, Victoria, Palestrina, and other High Renaissance composers. We usually do not sing composers such as Costanzo Festa, Adrian Willaert, Nicolas Gombert, Josquin des Prez, Johannes Ockeghem, and Pierre de la Rue.

Jeff’s Squeaky Soprano: To save rehearsal time, I created practice videos for my choir members who struggle with reading music. I’m a baritone, so you’ll have to pardon my squeaky Soprano voice:

REHEARSAL VIDEOS for each individual voice and the (free) PDF score await you at #54702.

Most readers won’t click on the individual voice parts, and that makes me sad. When we post a “scandalous” liturgical video, we get 40,000 views. I wish we could get as many views for the rehearsal videos—we must revive authentic sacred music!

    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

    “Gregorian Chant Quiz” • 24 March 2026
    How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!

    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.

    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

“We turn to the East when we stand to pray, since this is where the sun and the stars rise. It is not, of course, as if God were there alone and had forsaken the rest of creation. Rather, when these earthly bodies of ours are turned towards the more excellent, heavenly bodies, our minds are thereby prompted to turn towards the most excellent being, that is, to our Lord.”

— Saint Augustine of Hippo
