    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).
    —Jeff Ostrowski
    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.

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
