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.”

Jeff Ostrowski · July 3, 2021

E DON’T KNOW very much about how the Last Supper would have looked. Most scholars believe the Apostles and our Blessed Lord would have been laying down (“reclining”) as they ate. Some scholars have tried to guess how Jewish rituals might have influenced the early Christian rites and “disciplina arcana”—and Father Adrian Fortescue did as well. Because of the words “Postquam cœnatum est,” we know that the chalice our Lord consecrated was the fourth (last) Hallel cup. I am certainly not qualified to add to this type of scholarship in any way.

Dogs In Church: In spite of what certain internet authors assert, there is much we don’t know about the sacred liturgy even in “modern” times—such as the 16th century. Contemporaneous documents show it was quite common to bring dogs into church at that time. The noisy dog sounds were something prayerful Catholics complained about vociferously. What exactly did that look like? It’s doubtful there would have been silence in the nave of the church—even while complex polyphony was being sung! And people back in those days (who had to work so hard) often smelled bad … which is why incense was used according to some sources. Furthermore, how long did it take the Celebrant to pray the Canon? Examining the length of certain settings (SANCTUS + HOSANNA + BENEDICTUS + HOSANNA), it would seem the priest took a very long time saying the Canon.

Make It Fit Our Times: Therefore, Catholics have always needed to adapt traditional music to the sacred liturgy of the times. In today’s environment—for a variety of reasons—it might be imprudent to attempt a full Renaissance setting of the CREDO, which can easily last 9 minutes or more. Therefore, we are “stealing” something from the Germans. The Germans sing the Creed in plainsong, but switch to polyphony for the “Et Incarnatus Est” section. My choir has been singing Credo VII with added polyphonic sections.

An Example: I don’t like hearing my Soprano voice (I’m a Baritone), but my colleague Keven Smith has encouraged me to continue—so here’s my attempt at a simulation video:

—Based off something Father Guerrero published in 1566AD.

Rehearsal videos for each individual voice await you at #62964 .

Singing Is Physical: There is something I wish I could get across: Singing is physical. A recording device cannot reproduce a choral sound. The piano is a percussive instrument, and can be recorded with greater fidelity than a choir. What I’m trying to say is this: A choral sound is something physical, and microphones cannot capture it. We must form choirs; and this requires a minimum of three singers per part. When just two singers tackle a part, one voice will always dominate the other. You don’t have a choir until you have a minimum of three (3) singers per part. Four soloists singing SATB cannot substitute for an actual choir. Listen to this live hymn recording from last week at our parish and see whether you agree no individual voices “stick out.” Because choral music is physical—I’m talking about the sound waves created—there’s nothing as powerful as hearing a real choir sing in real life, especially if they are in “mixed formation.” I believe that we must form choirs and show priests how an actual choir sounds in real life; only then will we begin to see progress in the realm of Catholic Church music.

You can hear an excerpt of my choir singing that Guerrero Credo extension—but please realize that was the first time we attempted it, and it will improve as we continue to sing it.

    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.
