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). 😊
