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.”

Views from the Choir Loft

Guerrero’s Gloria from “Missa Iste Sanctus”

Jeff Ostrowski · May 9, 2017

N 2001, as a college sophomore, I began creating polyphonic rehearsal CDs for my church choir. The newspaper in Kansas was so fascinated by young people gathering to sing ancient music they featured us—and later, a television station ran a segment about us. (Perhaps there wasn’t much news in Kansas!) I recently came across a rehearsal track from 2004, which presents a HOSANNA. 1

Participants in this year’s Sacred Music Symposium will learn how to create these rehearsal videos, which I now produce by myself—so please forgive my soprano notes! Friday morning, I recorded a GLORIA by Guerrero:

    * *  PDF • GLORIA from Guerrero’s Missa Iste Sanctus

REHEARSAL VIDEOS for each individual voice await you at #5612.

I will soon release the KYRIE, SANCTUS, BENEDICTUS, HOSANNA, and AGNUS DEI.

WHAT IS THE POINT of all these rehearsal videos? Is this a waste of time, like so many other “internet projects” that make no difference in the real world? On the contrary, the results have been astounding. Just last week (30 April 2017) the first Latin Mass in fifty years was offered in Santa Barbara. The entire church was packed with more than 600 people. Even the choir loft was filled to the brim, and some had to stand for the whole Mass:

Santa Barbara Mass FSSP.la — 2395 Santa Barbara Mass FSSP.la — 2380 Santa Barbara Mass FSSP.la — 2258 Santa Barbara Mass FSSP.la — 2197 Santa Barbara Mass FSSP.la — 2177 Santa Barbara Mass FSSP.la — 2174 Santa Barbara Mass FSSP.la — 2170 Santa Barbara Mass FSSP.la — 2167 Santa Barbara Mass FSSP.la — 2141

Very few of our choir members read music, and some have just begun attending the Latin Mass. Rehearsal videos were indispensable in making sure the FSSP Apostolate in Los Angeles could provide worthy sacred music.

Someone kindly sent me an iPhone excerpt. But please remember microphones never capture choral sound accurately:


The choral sound is “harsh” on the tiny recording device. But I was there—and I can assure you it was anything but harsh.

DR. LUCAS TAPPAN often speaks of the beautiful choral sound found in England, and the following excerpt from Aylesford Priory (near Kent, England) in 1960 certainly demonstrates this, even in a simple little piece like Palestrina’s MISSA BREVIS:

Quick message for liturgical nerds: The priest almost makes a mistake by moving toward the center after the CHRISTE but corrects himself discreetly. Notice, too, his English pronunciation of the word “pax.” The priest butchers the intonation, so the choir pauses before beginning the GLORIA—undoubtedly so they can use the pitch pipe.

If you visit YouTube, you can view the entire video. Even their hymn singing, toward the beginning, is remarkable. Sometimes I’m tempted to get discouraged because our choral sound is still in need of improvement, but remembering Leonard Bernstein helps me. You see, Bernstein often gave “musical explanation sessions”—watched by millions—talking about classical music. When he demonstrated at the keyboard, his piano skills are frequently atrocious: no sense of line, sloppy passagework, and zero attention to counterpoint. I’ve heard children in the second grade perform better. (Bernstein clearly spent no time preparing, because he studied at Curtis with the legendary Vengerova and occasionally showed great keyboard skill, e.g. performing Gershwin.) If Bernstein got away with horrific playing, I console myself, our congregations will surely tolerate our imperfections, so long as we continue to improve.

183 Fr John Berg FSSP IEWING THAT VIDEO from 1960 makes me wonder how Catholic priests felt when the liturgical changes were imposed after Vatican II—especially since the majority of these changes were contrary to what the Council mandated. But the Traditional Mass has been discovered by a whole new generation of Catholics, and finds itself flourishing in a way “experts” assured us would never happen. This coming Sunday, an amazing opportunity comes to Los Angeles:

    REV. FR. JOHN BERG, FSSP
    Superior General, Priestly Fraternity of St. Peter
    Visiting from FSSP Headquarters in Switzerland
    CELEBRATING SOLEMN HIGH MASS (7:00pm)
    Sunday, 14 May 2017 • St. Victor’s Church
    8634 Holloway Dr • West Hollywood, CA 90069

Don’t miss this opportunity! We’d love to see you on Sunday.

As I said earlier, those of us who have discovered the Traditional Mass don’t understand how it could ever have been abandoned—but the same could be said about many other things. For example, nobody cared about J.S. Bach’s music toward the end of his life, because he was considered outdated (although that sounds inconceivable to us now). Or, consider another example. Modern liturgists have tried to convince us that all styles are “equally appropriate” for Mass, and publicly advocate inserting “commercial pop music” into the sacred liturgy. This bizarre notion is presented as unassailable, calling to mind something Leo Bozell (†1997) observed:

The argument moves from the existence of the thing to the correctness of the thing: what is, ought to be. Or, a popular variant: if a thing is, it doesn’t make any difference whether it ought to be—the correct response is to adjust, to learn to live with the thing.

Sing along with the Tenor rehearsal video (or any voice) given above. Or listen again to the Aylesford excerpt. Now brace yourself and listen to Techno based on Star Wars. Or listen to this Bach Concerto, masterfully played by Lipatti. If you really want a jolt, try the OCP song about the Giant Love Ball. Isn’t it apparent that different styles of music evoke different emotions? Who can deny that certain styles possess an inherent dignity—eminently suitable to the public worship of Almighty God—engendering prayerfulness, peace of soul, mystery, and wonder? Why must we be silent about this self-evident truth?




NOTES FROM THIS ARTICLE:

1   This was part of a full Mass setting I composed for my friend’s first Mass. By the way, I hear my younger brother’s deep bass voice on that 2004 recording, so I must have dragged him over from Benedictine college to help me. I was grateful for his help; he’s a fabulous musician.

    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!

    “Rare Photographs” • Hannibal Bugnini
    On 2 September 2025, we included in this article extremely rare photographs of Archbishop Hannibal Bugnini taken in Iran circa 1979. Bugnini had initially been banished by the pope to Uruguay, but he refused to obey. [This is interesting, since Bugnini relied upon ‘blind obedience’ when it came to modifications of the ancient liturgy.] After he refused to obey the order from the pope, Hannibal Bugnini was banished to Iran. You can also watch a short video of Hannibal Bugnini in Iran, dated 10 November 1979. That’s about a week after the USA embassy hostage crisis began in Tehran, and Pope Saint John Paul II had sent the leader of the Iranian Revolution a special letter.

    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.

    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.

“The plan to definitively abolish the traditional Tridentine Mass … if it is true, seems to me to be an insult to the history of the Church and to Sacred Tradition, a diabolical project that seeks to break with the Church of Christ, the apostles, and the saints.”
