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:

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.

    Music List • (5th Sund. Ordinary Time)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for this coming Sunday, 8 February 2026, which is the 5th Sunday in Ordinary Time (Year A). If such a thing interests you, feel free to download it as a PDF file. You will probably notice it isn’t as ‘complete’ or ‘spiffy’ as usual, owing to some difficulties which took place this week.

    PDF • “Communion” (5th Sunday in Ordin.)
    The COMMUNION ANTIPHON for this coming Sunday, 8 February 2026—which is the 5th Sunday in Ordinary Time (Year A)—is truly delightful. You can download the musical score completely free of charge. This text will be familiar to altar boys, because it’s PSALM 42. The Feder Missal makes the following claim about that psalm: “A hymn of a temple musician from Jerusalem: he is an exile in a heathen land, and he longs for the holy city and his ministry in the Temple there. The Church makes his words her own.”

    Funeral Music “Template” • For Families
    Many have requested the MUSICAL TEMPLATE for funerals we give to families at our parish. The family of the deceased is usually involved in selecting Number 12 on that sheet. This template was difficult to assemble, because the “Ordo Exsequiarum” has never been translated into English, and the assigned chants and hymns are given in different liturgical books (Lectionary, Gradual, Order of Christian Funerals, and so on). Please notify me if you spot errors or broken links. Readers will be particularly interested in some of the plainsong musical settings, which are truly haunting in their beauty.

    PDF Chart • “Plainsong Rhythm”
    I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”

    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.

Random Quote

According to the Instruction “Musicam sacram” of 5 March 1967, Article 34 §1, the polyphonic “Ordinarium Missae” can in the future still be sung suetis normis, “according to the customary norms,” i.e. by the choir. In fact, this form of the high Mass is placed in high relief compared to the other forms, among which the congregationally sung Gregorian chant Mass deserves our special attention.

— Monsignor Overath (President, “Consociatio Internationalis Musicæ Sacræ” founded by Pope Saint Paul VI
