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.”

Gregorian Chant … with Organ Accompaniment?

Jeff Ostrowski · April 6, 2026

AROLD C. SCHONBERG served as chief music critic for The New York Times from 1960 to 1980. Schonberg’s heart belonged to the grand Romantic tradition of performance—with its expressive individuality, big sound, and interpretive freedom—so we shouldn’t be astounded to learn that he was skeptical of the so-called ‘authentic instruments’ craze. Schonberg was ruthless towards advocates of ‘historically informed’ performances, who wrote verbose articles explaining in a pedantic and serious tone (!) that period instruments were “supposed” to play out of tune. But as time went on, performers learned how to play the older instruments in tune. In other words, the problem was a lack of technique, rather than any deficiency in the instruments themselves. In that sense, Schonberg was vindicated.

Period Instruments • In a moment, I’ll explain why I bring up the ‘early music’ movement. But first, please listen to this ‘live’ recording of our children’s choir joining our volunteer parish choir to sing the INTROIT on Holy Thursday:

Here’s the direct URL link.

That musical score can be downloaded free of charge at the flourishing feasts website.

(1 of 3) Authentic Performance • There was a time in my life when I believed the only ‘correct’ way of singing Gregorian Chant was a cappella by men only. The legendary Father Valentine Young, OFM, eventually made me realize how wrong I was. He showed me that plainsong accompanied on the pipe organ can be very beautiful. But I also love a cappella plainchant sung by just men. And I also cherish a cappella plainsong sung by females only. (The only version I hate is men and women in octaves a cappella, although that’s the way Westminster Cathedral in England always sang plainsong.)

(2 of 3) Authentic Performance • Someone might surmise that I’m a fan of ‘historically informed’ performances because I’ve spent the last three decades of my life studying adiastematic notation. As a matter of fact, I’m someone who’s quite skeptical of that movement. For instance, written correspondence has been discovered—from composers such as Sebastian Bach and Wolfgang Amadeus Mozart—in which they recount instances of their music being played by enormously large performing forces. The composers are ecstatic with joy! That suggests “smaller” performing forces were the result of financial limitations. Many ‘early music’ groups cover up or downplay such evidence … because large ensembles are quite a bit more expensive.

(3 of 3) Authentic Performance • Broadly speaking, I’m in favor of whatever produces the best music. For example, the performances I’ve heard played on a Piano-Forte pale in comparison to the interpretations by pianists of the Golden Age … and it’s not even close. In other words, who cares if something is performed on period instruments if the result is uninspired and dull?

Conclusion • There will always be people who say that when Mozart is performed by musicians wearing powdered wigs “it sounds better.” I reject such an idea. Is accompanied Gregorian Chant a development? Of course! On the other hand, the entire history of the Catholic Church includes development after development. For a long time, the pipe organ was forbidden (owing to certain associations it had). But as the centuries rolled along, those associations fell away—and the Second Vatican Council extolled the pipe organ’s use at liturgical services.

Addendum • For the record, I discovered a version of Nos Autem with a mysterious melody. Perhaps one of our readers could tell me whether they recognize it? Does anyone know its provenance?

    Responsorial Psalm Fauxbourdon?
    When it comes to singing Responsorial Psalms in Fauxbourdon, what does this sound like in practice? Can such a thing be done successfully with volunteer choirs in real Catholic parishes? Listen to this audio excerpt from Good Friday and see what you think. Our parish volunteer choir did so well this year—and the ceremonies were ‘standing room only’. For the record, that musical score can be downloaded (completely free of charge) from the flourishing feasts website.

    Music List • (Easter Sunday, 2026)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for Easter Sunday—a.k.a. “Ad Missam in die Paschae”—which is 5 April 2026. Please feel free to download it as a PDF file if such a thing interests you. The Fauxbourdon for Communion is particularly moving.

    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.

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

Let us ponder the incontrovertible fact that Eucharistic Adoration in the Ordinary Form (“Novus Ordo”) is always and everywhere celebrated “ad orientem.” Why, then, is there such opposition to Mass being celebrated in that way, which is actually stipulated by the 1970 Missal rubrics?
