    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.

    PDF Download • “Our Father” (1 page)
    Dutch organist, teacher, and conductor HERMAN STRATEGIER (d. 1988) studied under Hendrik Andriessen. He composed this unison setting with organ accompaniment for the LORD’S PRAYER (“Our Father”) which a children’s choir would find both within reach and worthy of the effort. The whole thing fits neatly on a single page. Strategier eventually became organist of Saint Catherine’s Cathedral in Utrecht. He also taught at the “Dutch Institute for Catholic Church Music” (Nederlands Instituut voor Katholieke Kerkmuziek).

    “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

“[Saint Jerome’s Latin] fairly frequently represents a purer text than does the existing Hebrew, sometimes yielding a plain sense when the Massoretic text fails to do so, and quite often providing a working interpretation of a passage where the Hebrew is doubtful.”

— Sebastian Bullough, O.P. (June 1949)
