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!

    PDF • “Music List” (Sunday, 28 December)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for Feast of the Holy Family of Jesus, Mary, & Joseph (28 Dec. 2025). If such a thing interests you, feel free to download it as a PDF file. The FAUXBOURDON verses for the Communion Antiphon are particularly gorgeous. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for Christmas Midnight Mass (“Ad Missam In Nocte”). If such a thing interests you, feel free to download it as a PDF file. The ENTRANCE CHANT is simple, but quite beautiful. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

    PDF • “Music List” (4th Sunday of Advent)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 21 December 2025, which is the 4th Sunday of Advent (Year A). If such a thing interests you, feel free to download it as a PDF file. The ENTRANCE CHANT is the famous “Roráte Coeli” and the fauxbourdon setting of the COMMUNION is exquisite. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

Quick Thoughts

    What does this mean? “Pre-Urbanite”
    One of the things informed critics have frequently praised vis-à-vis the Saint Jean de Brébeuf Hymnal has to do with its careful treatment of the ancient hymns vs. the “Urbanite” hymns. This topic I had believed to be fairly well understood—but I was wrong. The reason I thought people knew about it is simple; in the EDITIO VATICANA 1908 Graduale Romanum (as well as the 1913 Liber Antiphonarius) both versions are provided, right next to each other. You can see what I mean by examining this PDF file from the Roman Gradual of 1908. Most people still don’t understand that the Urbanite versions were never adopted by any priests or monks who sang the Divine Office each day. Switching would have required a massive amount of effort and money, because all the books would need to be changed.

    PDF Download • “Santo Santo Santo”
    Those searching for a dignified, brief, simple, bright setting of SANCTUS in Spanish (“Santo Santo Santo”) are invited to download this Setting in honor of Saint John Brébeuf (organist & vocalist). I wonder if there would be any interest in me recording a rehearsal video for this piece.

Random Quote

“Every medicine does not suit every stage of sickness; because the tonic given to those who are recovering from fever would be hurtful to them if given while yet in their feverish condition. So likewise Baptism and Penance are as purgative medicines, given to take away the fever of sin; whereas this sacrament [the Sanctissimum] is a medicine given to strengthen, and it ought not to be given except to them who are quit of sin.”

— Saint Thomas Aquinas Re: the EUCHARIST
