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!

    PDF Download • Introit (2nd Sn. Ord.)
    This coming Sunday, 18 January 2026, is the 3rd Sunday in Ordinary Time (Year A). The ENTRANCE CHANT is set according to the fourth mode, which sounds ‘serious’ or ‘dark’ or ‘haunting’ or ‘mysterious’—and its English adaptation corresponds to the authentic version (“Omnis terra adóret”) found in the GRADUALE ROMANUM. In this rehearsal video (click here) I attempt to sing the melody while simultaneously accompanying myself on the organ. I encourage you to print off the organ accompaniment (PDF) and play through it, because the harmonies are delightful.

    Spectacular Communion Setting!
    The FAUXBOURDON setting of the Communion for the Baptism of the Lord (which will occur this coming Sunday) strikes me as quite spectacular. The verses—composed by the fifth century Christian poet, Coelius Sedulius—come from a long alphabetical acrostic and are deservedly famous. The feast of the LORD’S BAPTISM was traditionally the octave day of Epiphany, but in the 1962 kalendar it was made ‘more explicit’ or emphasized. The 1970 MISSALE ROMANUM elevated this feast even further.

    PDF • “Music List” (Sunday, 11 January)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for Feast of the Baptism of the Lord (SUNDAY, 11 January 2025). If such a thing interests you, feel free to download it as a PDF file. The FAUXBOURDON verses for the Communion Antiphon—to say nothing of the antiphon itself—are breathtaking. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the monumental feasts website alongside the official texts in Latin.

    “Reminder” — Month of January (2026)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.

    PDF Download • “In Paradisum” in English
    We always sing the IN PARADISUM in Latin, as printed on this PDF score. I have an appallingly bad memory (meaning I’d be a horrible witness in court). In any event, it’s been brought to my attention that 15 years ago I created this organ accompaniment for the famous and beautiful ‘IN PARADISUM’ Gregorian chant sung in English according to ‘MR3’ (Roman Missal, Third Edition). If anyone desires such a thing, feel free to download and print. Looking back, I wish I’d brought the TENOR and BASS voices into a unison (on B-Natural) for the word “welcome” on the second line.

Random Quote

“There are no hymns, in this sense, till the fourth century; they were not admitted to the Roman office till the twelfth. No Eastern rite to this day knows this kind of hymn. Indeed, in our Roman rite we still have the archaic offices of the last days of Holy Week and of the Easter octave, which—just because they are archaic—have no hymns.”

— Adrian Fortescue (25 March 1916)
