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.”

“Benedictus” (Missa Iste Sanctus) • All voices recorded by Corrinne May

Jeff Ostrowski · December 21, 2021

OT LONG AGO, we spoke of the inscrutable decree by Bishop Robert E. Guglielmone, who declared that “the beauty of the Gregorian Chant” and a “sense of reverence” during the Holy Mass are “not consistent” with Vatican II. How can anyone believe such a claim? Vatican II said: “The musical tradition of the universal Church is a treasure of inestimable value, greater even than that of any other art” (SC §112). Vatican II said: “Choirs must be diligently promoted” (SC §114). Vatican II said: “the pipe organ is to be held in high esteem” (SC §120). Vatican II said: “The treasury of sacred music is to be preserved and fostered with great care” (SC §114).

Not Just Plainchant: Vatican II said Gregorian Chant must be given “first place” (SC §116) under ordinary circumstances, but also explicitly praised polyphony at Mass. Polyphony is the highest form of music, because each voice has its own melody. At the same time, thanks to the rules of counterpoint—which took hundreds of years to figure out—the independent melodies create harmony. In Masses by the great composers (such as Palestrina, Victoria, Morales, and Guerrero), the melodies themselves are based on Gregorian Chant, but sometimes the melodies are flipped upside down (inversion) or stretched out (augmentation).

They Could Not Kill This: The 20th century saw the decline of the arts, thanks to “sophisticated” avant-garde music.1 But polyphony survived, because sensible musicians realized it was the greatest music of all. Polyphony continued to be taught at secular universities, even by professors who (sometimes) were atheists! Regarding “contemporary” Catholic liturgical music—originally classified as The Hootenanny Mass—composer James MacMillan summarizes: “A lot of the favored new settings are musically illiterate, almost is if they were written by semi-trained teenagers, getting to grips with musical rudiments.” No serious conservatory would ever teach music by composers like David Haas, Rory Cooney, Marty Haugen, Michael Joncas, and Dan Schutte.

Another Reason: Polyphony also survived the “dark days” of the 1970s and 1980s because it’s an absolute delight to sing. The gorgeous lines by Father Francisco Guerrero practically sing themselves! And what a joy it is to work with fine singers! One of the greatest singers I know is my colleague, Corrinne May. She recently recorded all the voices for “Benedíctus Qui Venit” (Missa Iste Sanctus) by Father Guerrero. My singers really appreciate these rehearsal videos:

NOTES FROM THIS ARTICLE:

1   I can’t tell you about “avant-garde” music, because you won’t believe me. If I tell you composers wrote “music” which requires the pianist to fire a nuclear weapon into the audience, you won’t believe me. If I tell you composers wrote “music” which requires placing radios on the stage of Carnegie Hall and listening to static, you won’t believe me. If I tell you composers wrote “music” which requires the pianist to beat the piano strings with a dead fish, you won’t believe me. If I tell you composers wrote “music” which requires the audience to be placed on buses and taken around the city, you won’t believe me. But all those are examples of avant-garde music. There’s even a piece where the pianist just sits in front of the keyboard for 4 minutes and 33 seconds; and that is supposed to be “Classical Music.”

    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

It is known that the “mora vocis” is part of the compulsory rules of recital of the “Vaticana” and is indicated in the Editio typica and its reprints by a somewhat larger spacing of the neume (one space-line) within one group of neuma.
