Simple English Propers (Divine Mercy Sunday)

What would the Simple English Propers sound like harmonized as if they were Chabanel Psalms? That is, according to the principles of the Nova Organi Harmonia?

Cardinal Burke, Maestro Charles Cole, A Great Blog

“Afterwards I had an opportunity to speak with Cardinal Burke and he spoke of the importance of Sacred Music. We also talked about the Church Music Association of America and the important work which this organisation does. He went back to his office and returned with a gift for me . . .” — Mæstro Charles Cole

Why Is This Interview Not Better Known?

“We are today not another Church as 500 years ago. It is always the same the Church. What is one time holy for the Church is always holy for the Church and is not in [an] other time an impossible thing.” — Cardinal Ratzinger, speaking in English to Raymond Arroyo (2003)

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.”]
    —Jeff Ostrowski
    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!
    —Jeff Ostrowski
    “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.
    —Jeff Ostrowski

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

“Whether celebrated with priest and people facing each other or with priest and people together facing the same direction, every Eucharist is Christ coming to meet us, gracing us with a share in his own divine life.”

— Most Rev’d Arthur J. Serratelli (1 December 2016)

But we’re under pressure to transfer our website to a “subscription model.”

We don’t want to do that. We believe our website should remain free to all.
