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.”

Those who so desire may now download a live recording of my choir—which consists of 100% volunteer singers—singing the “Advent Kyrie” (KYRIE XVII) last Sunday.

“Urbanite Hymns” • What are those?

Dr. Aaron James, who earned a double doctorate, has stated publicly that the Saint Jean de Brébeuf Hymnal does a wonderful job explaining—by means of gorgeous color plates—the difference between the “Pre-Urbanite” hymns and those which were modified by Pope Urban VIII (d. 1644). Dr. James calls the Brébeuf treatment of the urbanite reform “a […]

28 November 2022 • FEEDBACK

“I can’t thank you enough for that four-part download of the Graduale with 5 lines. That is absolutely brilliant! Since I and another guy from the choir chant the Traditional Propers every Sunday, it has proven to be an invaluable resource. Great job of scanning it, too.” —Email received this morning from S.M.D.

PDF Download • “1st Sunday of Advent”

Those who accompany VESPERS FOR THE FIRST SUNDAY OF ADVENT may wish to download this draft copy. It’s the organ accompaniment I use, since my parish has Vespers (in the Extraordinary Form) with our congregation each Sunday afternoon. It looks pretty ‘junky’ but it gets the job done. Someday I hope to make a much […]

“Trochee Trouble” • Say What?

We have posted many articles discussing the French Vs. German way of interpreting syllabic plainsong—which some refer to as “Trochee Trouble.” Needless to say, we encourage everyone to carefully read all those articles. But some folks still don’t understand what “Trochee Trouble” is all about. Therefore, I have created this 1-Page Sheet that explains it […]

“Progress Made!” • 10-Nov-2022

My volunteer choir has felt the repercussions of this year’s (particularly severe) flu season. Nevertheless, I believe in always—always—giving one’s best as a choir director, even when many singers are absent. You can hear by this brief recording that our singers are starting to blend very nicely. And you can download that choral “warm-up” exercise […]

Mark Your Calendars!

Have you marked your calendar for Sacred Music Symposium 2023? The dates were recently revealed. You don’t want to miss this! This annual event has gained a reputation as the church music conference par excellence vis-à-vis Catholic musicians “in the trenches.”

A God We Cannot “See”

By the Incarnation, our Savior’s divinity was hidden. In the Eucharist, according to Saint Thomas Aquinas, our Savior also ‘hides’ His manhood. We cannot see God—although we can see Him (through faith) in the SANCTISSIMUM, in the eyes of the poor, in the grandeur of the mountains, and so forth. Hymn #746 in the Brébeuf […]

This Coming Sunday’s Introit

You can evaluate my attempt to record this Sunday’s INTROIT according to the official rhythm of the Catholic Church. This INTROIT is very well known because it’s repeated over and over at the end of the year, depending on how many Sundays after Pentecost occur in a particular year.

“Christ the King” • Introit

I have attempted to record the Introit for the Feast of Christ the King according to the official rhythm of the Catholic Church. You can view the YouTube recording of my attempt. Traditionally, our Savior’s “kingship” was celebrated as part of the Epiphany—but in 1925, Pope Pius XI created the “feast of Christ the King” […]

29 October 2022 • FEEDBACK

Good morning! My name is […] and I write to you from Chile. Just a short note to say: thank you for your wonderful website “Corpus Christi Watershed.” As a Catholic organist, I truly appreciate the marvelous work you have done. Your website is a tremendous library open to everyone. Thanks so much, and God […]

PDF Download • Plainchant on 5 lines!

I can’t think of better way to learn Gregorian chant than to download this 651-page PDF file, containing the marvelous Gregorian Vesperale (1915) by Father Karl Weinmann (d. 1929) printed on five lines. If you accompany Vespers directly from the plainsong notation, this makes life easy! It’s also fun to compare the Gregorian chant inside […]

    “Music List” • 22nd in Ordinary Time (Year C)
    Some have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 31 August 2025, which is the 22nd Sunday in Ordinary Time (Year C). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are conveniently stored at the spectacular feasts website alongside the official texts in Latin.
    —Jeff Ostrowski
    “The Worm That Dieth Not”
    My pastor asked me to write a column for our parish bulletin with reflections on the sacred liturgy and church music. In my most recent article, I discuss “The Worm That Dieth Not.” At this website, you can access it conveniently; simply scroll down to the one dated 31 August 2025.
    —Jeff Ostrowski
    A Nice Hymn In Spanish
    In my humble opinion, this is a really beautiful hymn in Spanish. If I practice diligently, I’ll be able to pronounce all the words properly. If you’re someone who’s interested in obtaining a melody only version (suitable for your congregational ORDER OF WORSHIP) you can steal that from this.
    —Jeff Ostrowski

Quick Thoughts

    Solemn “Salve Regina” (Chant)
    How many “S” words can you think of using alliteration? How about Schwann Solemn Salve Score? You can download the SOLEMN SALVE REGINA in Gregorian Chant. The notation follows the official rhythm (EDITIO VATICANA). Canon Jules Van Nuffel, choirmaster of the Cathedral of Saint Rumbold, composed this accompaniment for it (although some feel it isn’t his best work).
    —Corpus Christi Watershed
    Pope Pius XII Hymnal?
    Have you ever heard of the Pope Pius XII Hymnal? It’s a real book, published in the United States in 1959. Here’s a sample page so you can verify with your own eyes it existed.
    —Corpus Christi Watershed
    “Hybrid” Chant Notation?
    Over the years, many have tried to ‘simplify’ plainsong notation. The O’Fallon Propers attempted to simplify the notation—but ended up making matters worse. Dr. Karl Weinmann tried to do the same in the time of Pope Saint Pius X by replacing each porrectus. You can examine a specimen from his edition and see whether you agree he complicated matters. In particular, look at what he did with éxsules fílii Hévae.

Random Quote

“Who dreamed on that day that within a few years, far less than a decade, the Latin past of the Church would be all but expunged, that it would be reduced to a memory fading in the middle distance? The thought of it would have horrified us, but it seemed so far beyond the realm of the possible as to be ridiculous. So we laughed it off.”

— Most Rev’d Robert J. Dwyer, Archbishop of Portland (d. 1976)
