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.”

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!

    “The Worm That Dieth Not”
    My pastor asked me to write a column for our parish bulletin with reflections on the sacred liturgy and church music. In my most recent article, I discuss “The Worm That Dieth Not.” At this website, you can access it conveniently; simply scroll down to the one dated 31 August 2025.

    A Nice Hymn In Spanish
    In my humble opinion, this is a really beautiful hymn in Spanish. If I practice diligently, I’ll be able to pronounce all the words properly. If you’re someone who’s interested in obtaining a melody only version (suitable for your congregational ORDER OF WORSHIP) you can steal that from this.
    —Jeff Ostrowski
    “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 spectacular feasts website. When it comes to the feast of the Assumption (15 August 2025), I have uploaded the music list for that Mass—but not the “bi-lingual” Mass in the evening (Spanish, Latin, and English) which has completely different music.

Quick Thoughts

    Solemn “Salve Regina” (Chant)
    How many “S” words can you think of using alliteration? How about Schwann Solemn Salve Score? You can download the SOLEMN SALVE REGINA in Gregorian Chant. The notation follows the official rhythm (EDITIO VATICANA). Canon Jules Van Nuffel, choirmaster of the Cathedral of Saint Rumbold, composed this accompaniment for it (although some feel it isn’t his best work).

    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.

Random Quote

St Ambrose had to be “corrected” by Pope Urban VIII. The ‘Iste confessor’ was greatly altered and the hymn for the Dedication of a Church—which no one ought to have touched—was in fact completely recast in a new meter. Singular demand, made by the taste of that particular epoch!
