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.”

Positive Liturgical Fruits Of Vatican II: Second Part

I know people will attack me for saying this, but I’m against “concert Masses”—and I think that quote from “Sacrosanctum Concilium” backs me up.

President’s Corner

    “Music List” • 17th in Ordinary Time (Year C)
    Some have expressed interest in perusing the ORDER OF MUSIC I prepared for the 17th Sunday in Ordinary Time (27 July 2025). 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 the feasts website.
    —Jeff Ostrowski
    Communion • “Ask & You Shall Receive”
    All of the chants for 27 July 2025 have been added to the feasts website, as usual under a convenient “drop down” menu. The COMMUNION ANTIPHON (both text and melody) are exceedingly beautiful and ancient.

Quick Thoughts

    Pope Pius XII Hymnal?
    Have you ever heard of the Pope Pius XII Hymnal? It’s a real book, published in the United States in 1959. Here’s a sample page so you can verify with your own eyes it existed.
    —Corpus Christi Watershed
    “Hybrid” Chant Notation?
    Over the years, many have tried to ‘simplify’ plainsong notation. The O’Fallon Propers attempted to simplify the notation—but ended up making matters worse. Dr. Karl Weinmann tried to do the same in the time of Pope Saint Pius X by replacing each porrectus. You can examine a specimen from his edition and see whether you agree he complicated matters. In particular, look at what he did with éxsules fílii Hévae.

    Antiphons Don’t Match?
    A reader wants to know why the Entrance and Communion antiphons in certain publications deviate from what’s prescribed by the GRADUALE ROMANUM published after Vatican II. Click here to read our answer. The short answer is: the Adalbert Propers were never intended to be sung. They were intended for private Masses only (or Masses without music). The “Graduale Parvum,” published by the John Henry Newman Institute of Liturgical Music in 2023, mostly uses the Adalbert Propers—but sometimes uses the GRADUALE text: e.g. Solemnity of Saints Peter and Paul (29 June).

Random Quote

“From six in the evening, his martyrdom had continued through the ghastly night until nine o’clock in the morning. After fifteen hours of torture rarely if ever surpassed in the bloody annals of the Iroquois, the soul of Gabriel Lalemant was freed from its charred and mutilated prison and summoned to join his comrade Jean de Brébeuf in the radiant splendor of God. March 17th, 1649, was the date; for Brébeuf it had been the sixteenth.”

— ‘Fr. John A. O’Brien, speaking of St. Gabriel Lalemant’
