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.”

“Regína Caéli Laetáre” • 18 organ accompaniments

Jeff Ostrowski · April 12, 2023

APPROCHEMENT. Do you know what “rapprochement” means? It’s when two parties come to an understanding. Readers will probably agree that (many) Catholic priests and musicians need a rapprochement—but how can this be achieved? In my opinion, church musicians must follow the words of our Savior (Mt 10:16): “Be ye wise as serpents and innocent as doves.” Regrettably, most priests have never heard a decent choir singing in real life. I’m not talking about a QUARTET—because a soloist singing each part isn’t the same. I’m talking about a rich, sonorous, full, gorgeous choral sound, which I believe will move even a hardened soul when experienced in real life. Here’s a live recording of our volunteer choir singing the Recessional last Sunday:

Regína Cǽli Lætáre • Back in 2020, I posted seventeen (17) accompaniments for the simple Sálve Regína. I promised to do something similar for the other Marian antiphons, and today I offer eighteen (18) organ accompaniments—see below—for the simple Regína Coéli Laetáre. The vast majority follow the rhythmic markings of Dom André Mocquereau, which means they use a distinctive method of syncopating the chords. [Those interested in this should see pages 65-66 of The Politics of Plainchant in fin-de-siècle France by Katharine Ellis.] You can download the French singer’s score, but the Germans sing it differently.

Resplendent Not Repulsive • A word of caution, if I may. Earlier I said church musicians must be “wise as serpents.” For this reason, I suggest we must present music—at least initially—in a way that will attract people, rather than repulse them. Plainsong sung poorly (in a sluggish, lifeless manner) can leave a bad taste in people’s mouths. We who have been studying music for decades already fully understand the beauty of the Marian antiphons, and how important they are. Yet, I worry that if they are a presented in the wrong way, they can have the opposite effect of what we intend. In some (not all) parishes, it might be worth considering including “bright and accessible” pieces along with the Marian antiphons. Below is a live recording of our volunteer choir singing a hymn from the Brébeuf Catholic Hymnal last Sunday. When the women sing in unison, isn’t it gorgeous?

Eighteen Accompaniments • Below I’ve assembled eighteen (18) different organ accompaniments for the simple version of the “Regína Coéli Laetáre,” which is the Marian antiphon for Eastertide:

True Story • I had never heard of “Jan Kern”—but this morning I saw he’s mentioned by Monsignor Francis P. Schmitt on page 78 of Church Music Transgressed: Reflections on “Reform” (1977). How crazy is that? I just happened to be reading that exact page, whereas I had unsuccessfully searched the internet for information about Jan Kern moments earlier. Never forget: When you learn a new word, you’ll see it within 24 hours!

President’s Corner

    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.

    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.
    —Jeff Ostrowski
    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.
