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.”

Agnus Dei • “Missa Mille Regretz” by Fr. Cristóbal de Morales (d. 1553)

Jeff Ostrowski · October 3, 2017

OOKING AT MUSIC on the page is one thing, but hearing it real life is a different matter. I’ll never forget hearing Dr. Alfred Calabrese run through Guerrero’s KYRIE on the opening day of our very first Sacred Music Symposium. As a composer, I was in awe of what Guerrero had done: his grasp of musical DENSITY was life-changing. (No recording can capture this.)

These composers were aware of the overtone series, which is sometimes described as a series of “imaginary notes.” Let us consider an AGNUS DEI by Guerrero’s teacher, Fr. Cristóbal de Morales. The following recording—which I consider to be quite beautiful, especially for those familiar with this piece—was created by members of the volunteer choir I direct here at FSSP.la.

In measure 38, Tenors combine into unison on C—do you hear an imaginary girl’s voice singing a high G? (That’s a strong overtone.) Listen to the 1:31 marker:

REHEARSAL VIDEOS for each individual voice await you at #4297.
The full PDF score can be downloaded there.

Please download this Mp3, and listen to it carefully a billion times in your car:

…what a gorgeous piece!

THE FRATERNITY OF SAINT PETER in Los Angeles released a Promo Video celebrating the 10-year anniversary of “Summorum Pontificum.” The recording above was chosen as the soundtrack, and here’s a translation for the Chanson which Fr. Morales used as his melodic basis for Missa Mille Regretz:

Modern French:
Mille regrets de vous abandonner
et d’être éloigné de votre
visage amoureux.
J’ai si grand deuil
et peine douloureuse
qu’on me verra vite mourir.

English Translation:
A thousand regrets at deserting you
and leaving behind your loving face,
I feel so much sadness
and such painful distress,
that it seems to me my days
will soon dwindle away.

It’s fitting, in a way, because many priests I’ve asked about the 1960s reforms have expressed regret. When they opened up the new Missal for the first time (they explain) they saw that much of the beautiful symbolism and holy gestures of the ancient liturgy had been eliminated. As one bishop put it, “I knew it was gone for good.” Nobody at that time could have even hoped for something like “Summorum Pontificum.”

    PDF Download • “For Pentecost Sunday”
    Yesterday morning, I recorded myself singing the ENTRANCE CHANT for Pentecost Sunday while simultaneously accompanying myself on the pipe organ. Click here to see how that came out. At the end of the antiphon, there’s a triple Allelúja and I just love the chord at the end of the 2nd iteration. The organ accompaniment—along with the musical score for singers—can be downloaded free of charge at the flourishing feasts website. For the record, the antiphon on Pentecost Sunday doesn’t come from a psalm; it comes from the book of Wisdom.

    PDF Download • “Organ Accompaniment”
    Over the past few years, I’ve been harmonizing all the vernacular plainsong Introit settings by the CHAUMONOT COMPOSERS GROUP. This coming Sunday—10 May 2026—is the 6th Sunday of Easter (Year A). The following declaration will probably smack of “blowing my own horn.” However, I’d rank this accompaniment as my best yet. In this rehearsal video, I attempt to sing it while simultaneously accompanying myself on the pipe organ. The musical score [for singers] as well as my organ accompaniment can be downloaded free of charge from the flourishing feasts website.

    “Gregorian Chant Quiz” • 4 May 2026
    A few days ago, the CORPUS CHRISTI WATERSHED Facebook page posted this Gregorian Chant quiz regarding a rubric for the SEQUENCE for the feast of Corpus Christi: “Lauda Sion Salvatórem.” There is no audience more intelligent than ours—yet surprisingly nobody has been able to guess the rubric. Drop me an email with the right answer, and I’ll affirm your brilliance to everyone I encounter!

Quick Thoughts

    “Thee” + “Thou” + “Thine”
    Few musicians realize that various English translations of Sacred Scripture were granted formal approval by the USCCB and the Vatican for liturgical use in the United States of America. But don’t take my word for it! Here are four documents proving this, which you can examine with your own eyes. Some believe the words “Thine” and “Thou” and “Thee” were forbidden after Vatican II—but that’s incorrect. For example, they’re found in the English translation of the ‘Our Father’ at Mass. Moreover, the Revised Standard Version (Catholic Edition) mentioned in those four documents employs “Thine” and “Thou” and “Thee.” It was published with a FOREWORD by Westminster’s Roman Catholic Archbishop (John Cardinal Heenan).

    Simplified Version • “Canon in D” (Pachelbel)
    I published an article on 11 November 2023 called Wedding March For The Lazy Organist, which rather offhandedly made reference to a simplified version I created in 2007 for Pachelbel’s Canon. I often use it as a PROCESSIONAL for weddings and quinceañeras. Many organists say they “hate” Pachelbel’s Canon. But I love it. I think it’s bright and beautiful. I created that ‘simplified version’ for musicians coming to grips with playing the pipe organ. It can be downloaded as a free PDF if you visit Andrea Leal’s article dated 15 August 2022: Manuals Only: Organ Interludes Based on Plainsong. Specifically, it is page 84 in that collection—generously offered as a free PDF download. Johann Pachelbel (d. 1706) was a renowned German organist, violinist, teacher, and composer of over 500 works. A friend of Bach’s family, he taught Johann Christoph Bach (Sebastian Bach’s eldest brother) and lived in his house. Those who read Pachelbel’s biography will notice his connection to two German cities adopted as famous hymn tune names: EISENACH and ERFURT.

Random Quote

“The replies to this committee (of which Mgr Bugnini was the secretary) reveal a desire to reform the liturgy. In what sense? Out of 2,109 responses from bishops, just three expressed the desire to restore Communion under both kinds. There was a sizable demand for limited use of the vernacular, but only one French bishop wanted the entire Mass in French.”

— Fr. Dominic Allain (2019)
