“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.

“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 […]

“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 […]

    “Reminder” — Month of September (2026)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). Since we were founded in 2006, not one of our board members has ever accepted any remuneration whatsoever—not a penny. We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. It couldn’t be easier to subscribe! Just scroll to the bottom of any blog article and enter your email address.

    PDF Download • “Cordero de Dios”
    Feel free to download this setting of the “Cordero de Dios” (AGNUS DEI) in Spanish. The congregation gets an interesting melody within reach, the organist gets a straightforward accompaniment, and the person assembling the ORDER OF WORSHIP gets a ‘ready-to-paste’ plainsong version. Try this setting of the “Santo, Santo, Santo” (SANCTUS) if you desire one that’s easy to sing and includes a simple organ accompaniment. For the record, I have harmonized the Spanish “GLORIA” found in the MISAL ROMANO, Tercera Edición. Click here to download that.

Quick Thoughts

    Preface of Saint Joseph (added by the pope)

    You can see the “Præfatio de Sancto Joseph” inserted directly into the priest’s missal.

    “Predictable Rhymes?” • A Follow Up
    We received considerable correspondence regarding my article, Two Ways to Defile a Hymn. More specifically, what really raised certain people’s hackles was its follow-up article dealing with the keyboard accompaniment for the CHRIST THE KING HYMNAL. But to quote Eliza Doolittle: “Have I said anything I oughtn’t?” Please examine this PDF file and see whether you agree. Were the editors of the BRÉBEUF HYMNAL incorrect to insist upon sophisticated and clever rhymes, rather than mind-numbingly predictable rhymes?
    —Jeff Ostrowski
    ‘Ould’ But Not Good
    Dom Samuel Gregory Ould (note the spelling) was a Benedictine monk at FORT AUGUSTUS ABBEY in Scotland. As musician, organist, and composer, Dom Ould was highly regarded. Moreover, he was considered an authority on Gregorian Chant. But not everything found in an old book—or, in this case, an “Ould” book—is necessarily praiseworthy. Consider this page from Dom Ould’s hymnal. Do you see the rhymes? They offend severely by ABR (“Abuse By Reuse”) and are utterly predictable. In my recent article—Two Ways to Defile a Hymn—I addressed this topic.

Random Quote

“Unfortunately there are few organists or singers nowadays whose knowledge of Latin is sufficient to enable them to follow easily the meaning of the liturgical texts.”
