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.”

Don’t You Agree About These?

If you want to make Jeff Ostrowski really happy, send him an email with effusive praise about the individual voice recordings for hymn #296. [Soprano, Alto, Tenor, Bass] They came out dazzlingly sensational, don’t you agree?

Choral Vowels? Yes? No?

Here’s a live recording of one of the choral “warm-up” exercises my choir enjoys. It was taken during our rehearsal on 27 January 2023. It’s good to make sure each chord is perfectly in tune and balanced before moving to the next one. That only happens when each singer has the correct vowel. If you […]

26 January 2023 • FEEDBACK

“Jeff, I wanted to personally thank you for your spiritual witness at the Symposium & often blogs that you write too.

Good Friday Polyphony by L. Senfl

The editor of the Sacred Music Magazine recently made available to the public this splendid article by our own Charles Weaver. It includes an edition of polyphony for the GOOD FRIDAY “Reproaches.” Renaissance composers often set the various offices of Holy Week; e.g. readers will probably be familiar with the beautiful TENEBRAE setting by Father […]

Coming Soon! • Symposium 2023

A few weeks ago, dates were announced for Sacred Music Symposium 2023. The rehearsal videos are beginning to appear! For example, the KYRIE ELEYSON contains sections by Lassus, Victoria, and Palestrina. You can see and hear Part 1 at this link. Much more information about this wonderful conference will be released soon!

“Have We Gone Mainstream?”

A choir member alerted my wife to this video by Scott Hahn. You perhaps recognize a piece that’s been highly promoted by Corpus Christi Watershed: viz. Father Guerrero’s “Sanctus” from Missa Iste Sanctus. I would be interested to learn which choir made the recording (which heavily abbreviates the piece) and whether they used our rehearsal […]

Desperate! • Needing help after robbery

A few years ago, I had valuable books stolen. Recovery efforts with law enforcement have failed, so I’m reaching out to our readers. Can somebody help me obtain VOLUME II and VOLUME VIII of the Nova organi harmonia published in the 1940s and 1950s by the LEMMENSINSTITUUT? As far as I can tell, these volumes can’t […]

FEEDBACK … from New Hampshire

Jeff, thanks for the rare Gregorian accompaniments. I just love all the work you do! About 2 years ago, my parish made the decision to ditch all the contemporary Mass settings (Marty Haugen, and so forth) and to only use the Latin! We currently use the [name redacted of a disposable missal] … some of their accompaniments […]

2 January 2023 • FEEDBACK

Dear Mr. Ostrowski; I must politely disagree with your friend who said “absolutely nobody cares” about the rare books you share on the blog. The fact is, your raw enthusiasm for these resources teaches me (and presumably others) to care. I admit that sometimes the angles from which you present them—the amount of context, or […]

PDF • “Silent Night” Harmonization

Here’s a handy organ accompaniment (PDF) in three different key signatures: MIDDLE, HIGH, and LOW. The Latin lyrics (“Silens Nox”) are courtesy of Father Valentine Young, OFM (d. 2020). The organ harmonies are very simple, yet beautiful. Those who desire such a thing may also download a Singer’s Version. For obvious reasons, the choir will […]

23 December 2022 • FEEDBACK

A very skilled conductor from another country—who recently posted a recording any conductor would be proud of, displaying a light, pleasant, and professional choral sound—wrote to us on 23 December 2022: “CCWatershed and the Sacred Music Symposia have made a great mark in my musical career and the sound you hear you can proudly say […]

19 Dec. 2022 • “Include The Congregation?”

People often ask: “Can Gregorian Chant include the congregation?” The answer is: Yes! Listen to this Live Recording from last Sunday (which was the 4th Sunday of Advent). That is one model—not the only model—demonstrating how a congregation could be included. It’s KYRIE XVII, traditionally sung during Advent.

19 Dec. 2022 • “This One Has It All”

In case you missed it, this December 10th article about Dr. Peter Wagner, who founded the GREGORIAN ACADEMY at Fribourg (Switzerland), has it all: (1) A rare download [138 pages] of Dr. Wagner’s Kyriale Accompaniment Book; (2) Biographical information about Dr. Wagner; (3) A special surprise you’ll love; (4) Courtesy of Professor Weaver, a translation […]

    Music List • (2nd Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 2nd Sunday of Lent (1 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has magnificent propers. Its somber INTROIT is particularly striking—using a haunting tonality—but the COMMUNION with its fauxbourdon verses is also quite remarkable. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

    Like! Like! Like!
    You won’t believe who recently gave us a “like” on the Corpus Christi Watershed FACEBOOK PAGE. Click here (PDF) to see who it was. We were not only sincerely honored, we were utterly flabbergasted. This was truly a resounding endorsement and unmistakable stamp of approval.
    —Jeff Ostrowski
    Which Mass?
    In 1905, when the Vatican Commission on Gregorian Chant began publishing the EDITIO VATICANA—still the Church’s official edition— they assigned different Masses to different types of feasts. However, they were careful to add a note (which began with the words “Qualislibet cantus hujus Ordinarii…”) making clear “chants from one Mass may be used together with those from others.” Sadly, I sometimes worked for TLM priests who weren’t fluent in Latin. As a result, they stubbornly insisted Mass settings were ‘assigned’ to different feasts and seasons (which is false). To understand the great variety, one should examine the 1904 KYRIALE of Dr. Peter Wagner. One should also look through Dom Mocquereau’s Liber Usualis (1904), in which the Masses are all mixed up. For instance, Gloria II in his book ended up being moved to the ‘ad libitum’ appendix in the EDITIO VATICANA.

Quick Thoughts

    Extreme Unction
    Those who search Google for “CCCC MS 079” will discover high resolution images of a medieval Pontificale (“Cambridge, Corpus Christi College, MS 079”). One of the pages contains this absolutely gorgeous depiction of the Sacrament of Extreme Unction.
    —Corpus Christi Watershed
    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.”
    —Jeff Ostrowski
    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.
    —Jeff Ostrowski

Random Quote

Goupil deserves the name of martyr not only because he has been murdered by the enemies of God and His Church while laboring in ardent charity for his neighbor, but most of all because he was killed for being at prayer and notably for making the Sign of the Cross.

— St. Isaac Jogues (after the martyrdom of Saint René Goupil)
