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:

REHEARSAL VIDEOS for each individual voice and the (free) PDF score await you at #5305.

This “Benedictus” goes along with the SANCTUS and HOSANNA, which is #5454.

Rehearsal videos for the KYRIE (Missa Iste Sanctus) can be found at #5294

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.”

    “Reminder” — Month of April (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. It couldn’t be easier to subscribe! Just scroll to the bottom of any blog article and enter your email address.

    Simplified Accompaniment (Easter Hymn)
    Number 36 in the Brébeuf Hymnal is “At the Lamb’s high feast we sing,” an English translation for Ad Cenam Agni Próvidi (which was called “Ad Régias Agni Dapes” starting 1631). As of this morning, you can download a simplified keyboard accompaniment for it. Simply click here and scroll to the bottom. Many organists are forced to serve simultaneously as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult—which explains why choirmasters appreciate these simplified keyboard accompaniments. Sadly, many readers will click that link but forget to scroll to the bottom where the simplified PDF file is located.

    PDF Download • “Quasi Modo Sunday”
    The Introit for “Quasi Modo Sunday” (12 April 2026) is particularly beautiful. The musical score can be downloaded as a PDF file, and so can the organ accompaniment. The official language of the Catholic Church is Latin (whereas Greek is our mother tongue). Vatican II said Gregorian Chant must be given “first place” under normal circumstances. As a result, some parishes will rightly sing the authentic version. On the other hand, because so many USA dioceses disobey the mandate of Vatican II, some musicians sing plainsong in the vernacular. I have attempted to simultaneously accompany myself on the pipe organ while singing the English version. Although very few take advantage of it, the complete Proprium Missae is posted at the flourishing feasts website.

Quick Thoughts

    PDF Download • “Anima Christi”
    I received a request for an organ accompaniment I created way back in 2007 for the “Anima Christi” Gregorian Chant. You can download this PDF file which has the score in plainsong followed by a keyboard accompaniment. Many melodies have been paired with “Anima Christi” over the centuries, but this is—perhaps—the most common one.

    PDF • “Liturgical Law” (467 Pages)
    On Good Friday during the middle ages, the pope privately recited THE ENTIRE PSALTER. If you don’t believe me, see for yourself by reading this passage by Dom Charles Augustine Bachofen (d. 1943). His famous book—called “Liturgical Law: A Handbook Of The Roman Liturgy”—was published by the Benjamin Herder Book Company, which was the American arm (operating out of St. Louis, Missouri) of one of the world’s most significant Catholic publishers. Dom Charles Augustine Bachofen was born in Switzerland but spent his career between the Benedictine monasteries at Conception (Missouri) and Mount Angel (Oregon). His 1931 masterpiece, Liturgical Law can be downloaded as a PDF file … 467 pages!

    “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!

Random Quote

“A father cannot introduce mistrust and division among his faithful children. He cannot humiliate some by setting them against others. He cannot ostracize some of his priests. The peace and unity that the Church claims to offer to the world must first be lived within the Church. ”
