Corpus Christi Watershed

Pope Saint Paul VI (3 April 1969): “Although the text of the Roman Gradual—at least that which concerns the singing—has not been changed, the Entrance antiphons and Communions antiphons have been revised for Masses without singing.”

30 June 2021 • “External Solemnities”

A document from 1822 shows that 29 June, the Feast of Saints Peter and Paul, used to be a Holy Day of Obligation in the United States. By 1864 it was no longer a Holy Day of Obligation—but the bishops of the United States were asked to celebrate it “solemnly” on the following Sunday, which […]

28 June 2021 • (Live Rec.) Perfect Canon

A few weeks ago, we posted a perfect Canon by Giovanni Maria Nanino (d. 1607), who was a colleague of Palestrina. Here is a Live Recording by a volunteer choir. The score scrolls by as the singers perform it. It was recorded yesterday at Mass.

Our volunteer choir is frequently called upon—at the last second—to sing for first Masses, solemn high Masses, dedication Masses, and so forth. With the Brébeuf Hymnal, I can always pull out marvelous, wonderful, thrilling songs […]

One of our choristers recorded this audio excerpt from a recent rehearsal we had.

The proper rules of harmony and […]

President’s Corner

    “Music List” • All Souls (2 November)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 2 November 2025, which is the Commemoration of All the Faithful Departed (“All Souls”). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are conveniently stored at the top-notch feasts website alongside the official texts in Latin.
    —Jeff Ostrowski
    2-Voice Arr. • “Creator of the Starry Height”
    Do you direct a choir consisting of women or children only? (Some call this a “treble” choir.) Download a two-voice arrangement of Creator of the Starry Height set to the tune of IOANNES by clicking here and then scrolling to the bottom. In our times, this hymn is normally used during ADVENT, and the Latin title is: Cónditor alme síderum. It’s important to say “cónditor”—placing the accent on the antepenult—because ‘condítor’ in Latin means “one who embalms the dead.”
    —Jeff Ostrowski
    “Equal Voices” Choir Pieces
    My colleague, CORRINNE MAY, has posted some delightful compositions for equal voices: that is, choirs consisting of all men or all women. Included there are settings of the “Ave Maria” and “Tantum Ergo.” They strike me as relatively simple and not excessively lengthy. (In other words, within reach of volunteer singers.) Even better, all the scores have been made available as instant PDF downloads, completely free of charge. Bravo!
    —Jeff Ostrowski

Quick Thoughts

    Gospel Options for 2 November (“All Souls”)
    We’ve been told some bishops are suppressing the TLM because of “unity.” But is unity truly found in the MISSALE RECENS? For instance, on All Souls (2 November), any of these Gospel readings may be chosen, for any reason (or for no reason at all). The same is true of the Propria Missæ and other readings—there are countless options in the ORDINARY FORM. In other words, no matter which OF parish you attend on 2 November, you’ll almost certainly hear different propers and readings, to say nothing of different ‘styles’ of music. Where is the “unity” in all this? Indeed, the Second Vatican Council solemnly declared: “Even in the liturgy, the Church has no wish to impose a rigid uniformity in matters which do not implicate the faith or the good of the whole community.”

    “Our Father” • Musical Setting?
    Looking through a Roman Catholic Hymnal published in 1859 by Father Guido Maria Dreves (d. 1909), I stumbled upon this very beautiful tune (PDF file). I feel it would be absolutely perfect to set the “Our Father” in German to music. Thoughts?
    —Jeff Ostrowski
    New Bulletin Article • “12 October 2025”
    My pastor requested that I write short articles each week for our parish bulletin. Those responsible for preparing similar write-ups may find a bit of inspiration in these brief columns. The latest article (dated 12 October 2025) talks about an ‘irony’ or ‘paradox’ regarding the 1960s switch to a wider use (amplior locus) of vernacular in the liturgy.

Random Quote

[to the executioner] Sir Thomas More: “I forgive you right readily.” [gives him a coin] “Be not afraid of your office; you send me to God.” Archbishop Cranmer: “You’re very sure of that, Sir Thomas?” More: “He will not refuse one who is so blithe to go to him.” [kneeling, he places his head on the chopping block]
