President’s Corner

    “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.

    “Be Joyful Mary” • Organ Interlude

    Peter Piel (1835–1904), was a Roman Catholic composer named “Royal Music Director” under Wilhelm I, King of Prussia.

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.
    —Jeff Ostrowski

Random Quote

“Rarely indeed,” asserted Pope Benedict XV (2 October 1921), “has the idealism of art and the glory of the faith been joined in such perfect harmony” as in the works of Palestrina and fellow polyphonists.

— Quoted by Gerard Ellard SJ (Church history professor at St. Mary’s College, KS)
