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.”

Simple “Salve Regina” • Its Origins

In the past, I have attempted to determine the origins of the “simple” Salve Regina chant. When it comes to the so-called “restored” plainsong books, the earliest instance I can find (of the simple version) is in the LIBER RESPONSORIALIS, published in 1895, a marvelous book based upon the groundbreaking research of Dom Joseph Pothier. […]

“I’ll Keep Your Secret, Choirmasters!” • (Tell Jeff)

She claimed she’d rather die than sing “womb” at Mass, since she considered it to be a medical term.

Do You Recognize This “Christmas” Tune?

Over the last 70 years, ST VENANTIUS has fallen out of favor. One reason might be that many harmonizations of it are “chunky.” I was pleased to see the Brébeuf Hymnal adopted the harmonization by Dom Gregory Murray (probably the finest ever created for ST VENANTIUS). This morning, I created this pipe organ recording. The […]

“Corde Natus Ex Parentis” (SATB)

A few minutes ago, I uploaded an English SATB version of “CORDE NATUS EX PARENTIS” (an ancient Christmas hymn by Prudentius). A nifty Latin version is also available. The quickest way to download either is to visit #668 in the Portal and scroll down to where it says: Additional information about Hymn 668. Many people […]

Mandatory Advent Piece

Last Sunday, our volunteer choir sang “the mandatory piece” for ADVENT in these United States. Anyone interested can listen to the ‘live’ recording. The claim is sometimes made (erroneously) that this piece can be sung only during the final days of ADVENT. Such an assertion demonstrates a misunderstanding of where this piece came from and […]

“Silent Night” • Easy Organ Arrangement

Here’s a handy organ accompaniment (PDF) in three different key signatures: MIDDLE, HIGH, and LOW. The Latin lyrics (“Silens Nox”) are courtesy of Father Valentine Young, OFM (d. 2020). The organ harmonies are very simple, yet beautiful. Those who desire such a thing may also download a Singer’s Version. Choirs will ‘pick up’ this piece […]

Do You Recognize This Melody?

This morning, I attempted to record a hymn called BRISTOL. Click here to listen to what I produced. I’m trying to provide PIPE ORGAN RECORDINGS for any Brébeuf hymns which don’t (yet) have a choral recording. Thousands of rehearsal videos have been added—by real human voices—but there’s still more work to do. I know very […]

    “Music List” • 21st in Ordinary Time (Year C)
    Our choir returns on Sunday, 24 August 2025. Some have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for it, which is the 21st Sunday in Ordinary Time (Year C). 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 feasts website.
    —Jeff Ostrowski
    “Entrance Chant” • 21st Sunday Ordin. Time
    You can download the ENTRANCE ANTIPHON in English for the 21st Sunday in Ordinary Time (Year C) which is coming up on 24 August 2025. Corresponding to the vocalist score is this free organ accompaniment. It’s set in a melancholy mode, but if you heard my choir’s female voices singing it your soul would be uplifted beyond belief. If you’re someone who enjoys rehearsal videos, this morning I tried to sing it while simultaneously accompanying my voice on the pipe organ.

    “Music List” • 19th in Ordinary Time (Year C)
    Some have expressed interest in perusing the ORDER OF MUSIC I prepared for the 19th Sunday in Ordinary Time (10 August 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 feasts website.

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

“Of course, the Latin language presents some difficulties, and perhaps not inconsiderable ones, for the new recruits to your holy ranks. But such difficulties, as you know, should not be reckoned insuperable. This is especially true for you, who can more easily give yourselves to study, being more set apart from the business and bother of the world.”

— Pope Saint Paul VI (15 August 1966)
