Mr. Ostrowski shares a ‘quick thought’ regarding the topic of the sacred liturgy.

Reminder!

Sometimes men—usually not women—brag publicly about how much money they make. It’s important to remember that everything (everything) comes from God, and we’ll be held responsible for every cent. Anything we currently possess is only thanks to God, Who gave us our bodies, minds, health, energy … indeed, our very existence. Only a foolish and […]

Live Recording • “Entrance Chant” (14th Sunday in Ordinary Time, Year B)

In the 1970s, some musicians felt that annihilating the Mass propers would lead to “freedom”—but the opposite was true.

This Sunday I begin service at my new church in Michigan. If you’re curious about the musical lineup for the Spanish Mass, feel free to download the Order of Music I created for the 14th Sunday in Ordinary Time, Year B. I tried to be sensitive to what the parish was doing before my arrival […]

“People’s Mass Book” • Omer Westendorf

On page 226 of the “People’s Mass Book” (1964), you’ll discover the “TOULON” melody used several times in the Brébeuf Catholic Hymnal, whose editorial team made it clear they had zero interest in “ginning up” a brand new hymnody tradition. Many of the melodies in the Brébeuf Hymnal were used by hundreds of Catholic hymn […]

President’s Corner

    Luis Martínez Must Go!
    Sevilla Cathedral (entry dated 13 December 1564): The chapter orders Luis Martínez, a cathedral chaplain, to stay away from the choirbook-stand when the rest of the singers gather around it to sing polyphony—the reason being that “he throws the others out of tune.” [Excerpt from “The Life of Father Francisco Guerrero.”]

    Urgent! • We Desperately Need Funds!
    A few days ago, the president of Corpus Christi Watershed posted this urgent appeal for funds. Please help us make sure we’re never forced to place our content behind a paywall. We feel it’s crucial that 100% of our content remains free to everyone. We’re a tiny 501(c)3 public charity, entirely dependent upon the generosity of small donors. We have no endowment and no major donors. We run no advertisements and have no savings. We beg you to consider donating $4.00 per month. Thank you!

    “Booklet of Eucharistic Hymns” (16 pages)
    I was asked to create a booklet for my parish to use during our CORPUS CHRISTI PROCESSION on 22 June 2025. Would you be willing to look over the DRAFT BOOKLET (16 pages) I came up with? I tried to include a variety of hymns: some have a refrain; some are in major, others in minor; some are metered, others are plainsong; some are in Spanish, some are in Latin, but most are in English. Normally, we’d use the Brébeuf Hymnal—but we can’t risk having our congregation carry those heavy books all over the city to various churches.

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

“At the hour for the Divine Office, | as soon as the signal is heard, | let them abandon whatever they may have in hand | and hasten with the greatest speed, | yet with seriousness, so that there is no excuse for levity. | Let nothing be preferred to the sacred liturgy.”

— Rule of St. Benedict (Chapter 43)
