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.”

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.
    —Jeff Ostrowski
    Jeff’s Mother Joins Our Fundraiser
    To assist our fundraiser, Mrs. Kathleen Ostrowski has drawn several beautiful sketches which she offers to all our readers free of charge. If you have a moment, I invite you download them at this link.

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.
    —Corpus Christi Watershed
    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

“The unity of language in the liturgy is so great a treasure for the Church that no advantage could compensate for its demise.”

— Dom Anselmo Albareda (2 January 1953), Father Nicola Giampietro, page 249
