FEEDBACK … from New Hampshire

Jeff, thanks for the rare Gregorian accompaniments. I just love all the work you do! About 2 years ago, my parish made the decision to ditch all the contemporary Mass settings (Marty Haugen, and so forth) and to only use the Latin! We currently use the [name redacted of a disposable missal] … some of their accompaniments […]

2 January 2023 • FEEDBACK

Dear Mr. Ostrowski; I must politely disagree with your friend who said “absolutely nobody cares” about the rare books you share on the blog. The fact is, your raw enthusiasm for these resources teaches me (and presumably others) to care. I admit that sometimes the angles from which you present them—the amount of context, or […]

“Sacred Time” Framed on our Wall

According to Cardinal Ratzinger “man is woven into the fabric of the universe. Time is first of all a cosmic phenomenon. Man lives with the stars.”

Gregorian Rhythm Wars • “Chorale and Chant Carefully Considered” (2 Jan 2023)

“The equalist plainchant of the High Middle Ages is as far removed from the rhythmic chant of the Early Middle Ages as the isometric chorales are from their rhythmic predecessors.” —Patrick Williams

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.

    “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

Although the New Testament is now so much more important to us than the Old, we must remember that the archetype of the Canon of Scripture is the Old Testament. At first that was the whole Bible, to Christians as to Jews. When the apostles speak of “Scripture” they mean the Old Testament only. Indeed, the way in which the books of the New Testament came to be considered canonical was by making them equal to those of the Old.

— Rev’d Doctor Adrian Fortescue
