    A Popular “Gloria” … in Dutch?
    Close to 16 years ago, I composed a “Glory to God in the Highest” in honor of SAINT RALPH SHERWIN. It was subsequently sung all over the world, and included in various collections (under different titles). You can download the musical score in plainsong notation. It was selected for inclusion in the Saint Isaac Jogues Illuminated Missal, Gradual, and Lectionary—and here’s its keyboard accompaniment (PDF file). I have a terrible memory, but somebody reminded me it was translated into Dutch (!) in 2012. I have no idea who did this—but you can download the score by clicking here. Because I don’t speak Dutch, I have no idea whether the adaptation was done skillfully.

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

“The tradition of Roman documents establishes a clear hierarchy. Gregorian chant has pride of place; classical polyphony has a privileged role. It is because styles carry with them associations and even evoke a place—the style of a Broadway show tune evokes the theater; the style of cocktail music evokes the cocktail bar, yet we hear these styles in church. The priority of sacred styles needs re-emphasis.”

— Dr. William Peter Mahrt
