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.”

Extremely Rare! • Pages from the “Directorium Chori” (Solesmes Abbey, 1864)

The entire edition was destroyed in a fire (circa 1866) except four rare copies.

Dom Pothier • “To The Eyes And To The Ears”

For years, I couldn’t understand this business about “the eyes and the ears.” What did Pothier mean? Then it hit me. • Topics include Dom Joseph Pothier, the mora vocis, Abbot Pothier’s brother (Dom Alphonse Pothier), Dom Lucien David, Dom Paul Jausions, and a truly magnificent story about Pope Pius X and Abbot Pothier, which is essential reading+

    PDF • “Music List” (1st Sunday of Advent)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 30 November 2025, which is the 1st Sunday of Advent (Year A). If such a thing interests you, feel free to download it as a PDF file. The ENTRANCE CHANT is quite memorable, and the fauxbourdon setting of the COMMUNION is exquisite. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

    “Music List” • Christ the King Sunday
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 23 November 2025, which is the 34th Sunday in Ordinary Time (Year C). If such a thing interests you, feel free to download it as a PDF file. In the 1970 Missal, this Sunday is known as: Domini Nostri Jesu Christi Universorum Regis (“Solemnity of Our Lord Jesus Christ, King of the Universe”). As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are conveniently stored at the magnificent feasts website alongside the official texts in Latin.

    “Simplified” Keyboard Accompaniment (PDF)
    I’d much rather hear an organist play a simplified version correctly than listen to wrong notes. I invite you to download this simplified organ accompaniment for hymn #729 in the Father Brébeuf Hymnal. The hymn is “O Jesus Christ, Remember.” I’m toying with the idea of creating a whole bunch of these, to help amateur organists. The last one I uploaded was downloaded more than 1,900 times in a matter of hours—so there seems to be interest in such a project. For the record, this famous text is often married to AURELIA, as it is in the Brébeuf Hymnal. The lyrics come from the pen of Father Edward Caswall (d. 1878), an Oratorian priest.

Quick Thoughts

    “Reminder” — Month of November (2025)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

    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?

Random Quote

“Both priests and people in this country [viz. ENGLAND] were largely taken by surprise by the recent restoration of the Easter Vigil, by the changes in the laws of fasting for Holy Communion, and the advent of the Evening Mass.”

— Dom Oswald Sumner (1955)
