Luis Martínez Must Go!

This notice shows that in Seville, as elsewhere, polyphonic singers clustered around a large open choirbook set on a stand in the middle of the grilled choir-enclosure.

PDF Download • “Glory To God” for Congregation & Choir (Mass of Saint Noël Chabanel)

“Defending the English” • Brief Riposte from Uganda

“As for the subject of whether the music of Tallis, Taverner, and Tye was tainted by the reformation, I would agree with Mr. Ostrowski.” —Reader from Uganda

    The formatting of this booklet is ‘messy’—but it’s only ever seen by the singers (not the congregation).

    Twenty-Two (22) English Translations
    We gathered every English translation of “Creátor Alme Síderum” ever made by Catholic poets, priests, bishops, cardinals, and saints (22 in all). Click this link to see them displayed, placed directly alongside the original Latin. Some are strikingly beautiful (e.g. “Great Maker of the glitt’ring stars”) and together they trace the hymn back to the ancient “Cónditor Alme Síderum,” which POPE URBAN VIII reworked in 1632AD.

    Stained Glass Window • Father Brébeuf
    Saint John de Brébeuf was one of the North American Martyrs. The photograph of a gorgeous stained glass window depicting Father Brébeuf was sent to us by Courtney Roberson. Father Brébeuf and his companions were canonized by Pope Pius XI on 29 June 1930. We are told this window is found in the Cathedral of Peoria, Illinois.

    “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.

Random Quote

“[Sacrosanctum Conclium’s implementation was] horrible, if we judge the debate on the liturgy as we have it today. Very few bishops would be proud to say they had a hand in it. Communion in the hand was never mentioned in the debate, neither was the word table (mensa) to take the place of altar—place of sacrifice… In my opinion the Debate on the Liturgy has been hijacked. The Council was…to reform, not to change completely.”

— Bishop Ignatius Doggett (who took part in Vatican II)
