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.”

Mesmerizing Credo Setting (SATB) • After Machaut

Jeff Ostrowski · April 3, 2017

HIS YEAR’S Symposium will be spectacular, and the response—from all over the world—has been overwhelming. The musical program, which is close to being finalized, almost seems a direct response to an article I wrote last January entitled True Vs. False Diversity. We have a bewildering variety of styles, and new works by famous composers will be revealed.

The Credo, arranged by Chaumonot, uses 14th-century polyphony by a Catholic priest named Guillaume de Machaut, who died in 1377AD:

Fr. Machaut’s harmonies begin at the 0:28 marker:

REHEARSAL VIDEOS for each individual voice—along with PDF score—await you at #5984. If you like them, please consider donating $5.00 per month.

274 CREDO TWO YOUNG LADIES IN HIGH SCHOOL, Sarah and Jacqueline, generously helped record the rehearsal videos for these 14th-century harmonies. Sing through each individual line (cf. #5984) because the power is revealed “horizontally.” We created the rehearsal videos to help choirmasters, who have such a difficult vocation! Just the other day, I was pondering how many things music directors do behind the scenes that nobody sees. Even staying in contact with the choir members—phone calls, text messages, emails, and so forth—requires much time and energy. It’s truly a “twenty-four seven” job.

The PDF score mentions how Canon Machaut lived during a difficult period of church history. The Avignon papacy and the Western Schism were both longer in duration than I’d realized. The times in which we live are also difficult, especially from the standpoint of certain members of the hierarchy. Last month, for example, I read a scandalous interview with a high-ranking cardinal that can only be described as disgusting and heretical. For myself, I find it comforting to study history and recall how much the Church has withstood.

Good Catholics in those days sought divine assistance, and we must do the same. Moreover, when you examine the 14th-century Credo used for Chaumonot’s edition, you’ll agree they certainly knew how to create beautiful manuscripts in those days!

    “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.

    This Sunday’s Communion Antiphon
    This coming Sunday—10 August 2025—is the 19th Sunday in Ordinary Time (Year C). The COMMUNION ANTIPHON is really gorgeous, and two of its features are worth mentioning. First of all, the Gospel reading assigned is from Saint Luke, whereas the the antiphon—although it matches the account—comes from Saint Matthew. (If anyone can point to a similar example, please notify me.) Furthermore, if you look at the authentic Gregorian Chant version posted on the feasts website, you’ll notice that it’s MODE III but ends on the ‘wrong’ note. A comparable instance of such a ‘transposed’ chant would be KYRIE IV.

    Using “Ye” Vs. “You” Correctly
    Using “Ye” vs. “You” is rather tricky, because it depends upon which era one is trying to recreate—if that makes any sense. In other words, the rules haven’t always been the same for these two. Nevertheless, Father Philip George Caraman (the legendary Jesuit scholar) gives us a masterclass using Saint Luke’s Gospel. Father Caraman was close friends with Monsignor Ronald Knox, Evelyn Waugh, and Sir Alec Guinness.

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

“To me nothing is so consoling, so piercing, so thrilling, so overcoming, as the Mass, said as it is among us. I could attend Masses for ever, and not be tired.”

— John Henry Cardinal Newman (1848)
