What Exactly Is Dr. Peter Wagner Talking About?

“These manuscripts had to be sought out in the public or capitular libraries, whose conservators were often hardly supportive of—if not outright hostile to—the reproduction of their treasures.”

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 […]

    PDF • “Organ Interlude” (Manuals Only)
    Monsignor Franciszek Walczyński (d. 1937) was a Polish composer. If you play the pipe organ, I encourage you to try out this ORGAN INTERLUDE FOR MANUALS ONLY (1-page PDF) which he composed. Walczyński taught plainsong at the seminary in Tarnów (about 50 miles east of Kraków). With his brother Stanisław—also a Catholic priest—he initiated the Saint Adalbert Society for the Support of Church Music, which ran annual workshops for their diocese. In July of 1894 (more than a decade before the appearance of the Editio Vaticana) Walczyński lectured on “congregational singing and Gregorian Chant.” On top of all that, Monsignor Walczyński founded an organists’ school in Tarnów and the SAINT ADALBERT CHOIR at the cathedral.

    Knox. Has. No. Equal.
    Dr. Finberg (of the University of Leicester) famously said: “No living writer possesses a greater command over the English language than Monsignor Ronald Knox.” A lifetime spent among his works would not exhaust them; always another thing to see, never once a reason to look away. Consider the marvelous way Knox Englished the famous VERBUM SUPERNUM of Saint Thomas Aquinas. The 4th verse (in Latin) means: “By being born, He became man’s companion; at this supper, He became man’s food; in dying, He became man’s ransom; in reigning, He is man’s reward.” Knox brilliantly makes the English fit the Latin meter: The manger, Christ their equal made, | That upper room, their souls’ repast, | The Cross, their ransom dearly paid, | And heav’n, their high reward at last. I believe the meaning of the French word “manger” was not absent from his thoughts when he penned that stanza.

Quick Thoughts

    “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.

    “Reader Feedback” • 22 June 2026
    A reader wrote to us from Virginia: “I really appreciate the 23 harmonizations that you posted on CORPUS CHRISTI WATERSHED for the Daily, Daily, Sing to Mary hymn. I hope to find willing voices in our small Schola Cantorum to try the three-voice version. Carry on, sir! You’re doing the Lord’s work.” While we don’t know this gentleman personally, we note that he earned a Ph.D. (which demonstrates that our blog has something for everybody). 😊

Random Quote

Father Richard John Neuhaus once said, reflecting on his experience of a liturgical week held in Washington, D.C., after the Second Vatican Council, that he imagined the voices of the pre-conciliar Liturgical Movement lamenting: “That is not what we meant. That is not what we meant at all.”

— Father Richard John Neuhaus was a Roman Catholic priest
