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.”

“Novus Ordo Parish … With Polyphony?” • Is that possible? How specifically does that work?

O SERIOUS PERSON would deny a great rupture occurred in the late 1960s. Before that time, the Mass was layered—meaning multiple things took place simultaneously. For instance, the SANCTUS was sung while the priest was praying the Canon. This was not unique to the Roman Rite. Every other Catholic rite was thus layered: the Alexandrian rites; the Byzantine rites; the Chaldean rites; and so forth. According to Father Adrian Fortescue: “The Eastern rites have developed this principle of simultaneous prayers much more than in the West. Large portions of their liturgies may be described as two services going on at once, one performed by the celebrant in a whisper at the altar, the other sung by the people, led by the deacon, outside the Ikonostasion (where there is one).” But starting in 1970, the Roman Rite became linear,1 except for a few spots. One such spot is the ENTRANCE CHANT, sung while the celebrant incenses the altar. Our choir recently returned from summer vacation, and here’s a live recording of them singing the ENTRANCE CHANT on 31 August 2025:

Here’s the direct URL link.

Offertory Incense • Another ‘non-linear’ spot in the Novus Ordo is the OFFERTORY. Below is a live recording of our choir singing Hymn #505 at that same Mass (31 August 2025) while the priest incenses the altar. The part where the voices ‘split’ into harmonious lines is not to be missed:

Reacting to Rupture • Broadly speaking, however, the 1970 MISSALE ROMANUM got rid of layering, and—as noted above—that’s a major rupture. Psychologists warn against “maladaptive rumination” (i.e. constant negative thoughts), and Father Valentine Young said something along those same lines:

“Looking back over my life, I probably suffered more from things that never happened than from things that actually did.”

Are we called by God to spend all our time ruminating over that rupture? Should we spend 4 hours each morning lamenting it and 4 hours each afternoon complaining about it? Wouldn’t it be better to accept the hand we’ve been dealt and then—having offered our lives to Christ—do the very best we can?

Polyphony for the Ordinary Form • The Second Vatican Council solemnly declared: “The treasury of sacred music is to be preserved and fostered with very great care” (SC §114). However, because the Novus Ordo is not a ‘layered’ service, it’s sometimes difficult to follow the mandate of Vatican II. Many have written to us asking some variant of the following question:

“How can choirmasters introduce
polyphony to the Ordinary Form
without getting fired?”

Jeff’s Solution • Well, for the past fifteen years, I’ve urged readers to consider using something I call “choral extensions.” But many still request specific instruction on how exactly such extensions work in real life. To that end, I have assembled the following list:

(a) Here’s an example of a “choral extension” for the KYRIE by William Byrd. You can learn more about that by locating #88208 at LALEMANT POLYPHONIC. The following was recorded live last week by our volunteer choir, and the “choral extension”—our way of complying with SACROSANCTUM CONCILIUM §114—comes at the end:

*  Mp3 Download • “Byrd Kyrie” (CHORAL EXTENSION)

(b) Here’s an example of a “choral extension” for the ALLELUIA by Giovanni Pierluigi da Palestrina. You can learn more about that by locating #26561 at LALEMANT POLYPHONIC. The following was recorded live last week by our volunteer choir. Again, the “choral extension” (our way of complying with SACROSANCTUM CONCILIUM §114) comes at the very end:

*  Mp3 Download • Palestrina Alleluia (CHORAL EXTENSION)

(c) Here’s an example of a “choral extension” for the AGNUS DEI by Zipoli. You can learn more about that by locating #28784 at LALEMANT POLYPHONIC. The following was recorded live last week by our volunteer choir:

*  Mp3 Download • Zipoli “Agnus Dei” (CHORAL EXTENSION)

(d) This one is not strictly speaking a “choral extension” (per se). It’s the gorgeous fauxbourdon verses we sing for the COMMUNION ANTIPHON, as found on the feasts website. The following was recorded live last week by our volunteer choir. The haunting “Glory be” at the end is not to be missed:

*  Mp3 Download • Communion Fauxbourdon

If you listen carefully, you can hear a few members of the congregation trying to join in. They’re not supposed to join in, but we must not blame them for being confused, because faithful Catholics have been jerked around (liturgically-speaking) for the last 60+ years. It’s going to take some time to reëstablish traditions.

Final Thoughts • On a weekly basis, we involve the congregation in many pieces; not just the first section of each choral extension. For instance, they love singing melodies from the Brébeuf Catholic Hymnal. We also make plenty of room for unaccompanied plainsong. Here’s an example from last Sunday:

Here’s the direct URL link.

Renewal of Challenge • In many recent articles, I’ve been recommending the Brébeuf Catholic Hymnal. I believe this book is indispensable for any serious Catholic choirmaster. (I certainly couldn’t run my choral program without it.) I don’t use the “P-word” word lightly, but I’m comfortable calling the BRÉBEUF HYMNAL peerless. Indeed, one of the main authors for the Church Music Association of America weblog declared (6/10/2022) that the BRÉBEUF HYMNAL “has no parallel and not even any close competitor.” For years, I’ve been searching for a qualified partner who’s willing to debate this assertion over zoom. Today—9 September 2025—I respectfully renew my challenge. Our website garners millions of hits, but so far nobody has accepted my challenge.

1 The Extraordinary Form was like a movie in which the soundtrack, the videography, the sound effects, and the dialogue all took place simultaneously. But in the MISSALE RECENS, only one thing happens at a given time. If the MISSALE RECENS follows the course of every other rite in history, it will become ‘layered’ as time goes on. According to Dr. Adrian Fortescue (who taught at the seminary alongside Monsignor Knox at SAINT EDMUND’S, WARE): “In the Eastern rites constantly the celebrant says one set of prayers while the deacon chants aloud other prayers with the people.”

    PDF Download • “Sprinkling Rite”
    Liturgical reformers who gained power after Vatican II frequently caused great suffering to musicians. With the stroke of a pen, they sometimes make changes that would require thousands—or even millions—of man hours (work undertaken by composers and editors). The Sprinkling Rite during Eastertide is but one tiny example. The version given in that PDF document was the original melody for Roman Missal, Third Edition. Some still prefer that version. However, at the last moment, an “unknown hand” tinkered with a few notes in the antiphon. Those who examine the current edition can verify this with their own eyes.

    ‘Sarum’ Good Friday?
    Plainsong of the Roman Rite has many variants—i.e. slight ‘variations’ or ‘alterations’ made to the ancient melodies. Variants often thrive in particular religious orders. Likewise, before Henry VIII broke away from the Catholic Church, Gregorian Chant variants were frequently associated with individual cathedrals in England: Hereford, Lincoln, Salisbury, and so forth. In the early 20th century, the (Anglican) organist at Westminster Abbey married “Let All Mortal Flesh Keep Silence” to this beautiful variant melody from England. Those who sing Gregorian Chant on Good Friday will recognize the melody. What do you think of this pairing?

    PDF Download • “Eb Organ Postlude”
    Gustav Adolf Merkel (d. 1885) was a German organist, teacher, and composer. Although a Lutheran himself, he held the appointment at the (Roman Catholic) Cathedral of Dresden from 1864 until his death. You can download his Organ Postlude in E-Flat, which I like very much. He has an interesting way of marking the pedal notes. What do you think?

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

“Young people have entrusted me with their absolute preference for the Extraordinary Form… […] But, above all, how can we understand—how can we not be surprised and deeply shocked—that what was the rule yesterday is prohibited today? Is it not true that prohibiting or suspecting the Extraordinary Form can only be inspired by the demon who desires our suffocation and spiritual death?”

— Cardinal Sarah to Edward Pentin (23 September 2019)
