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 • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.

    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.

    PDF • “Music List” (Xmas Midnight Mass)
    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.

Quick Thoughts

    PDF Download • “In Paradisum” in English
    We always sing the IN PARADISUM in Latin, as printed on this PDF score. I have an appallingly bad memory (meaning I’d be a horrible witness in court). In any event, it’s been brought to my attention that 15 years ago I created this organ accompaniment for the famous and beautiful ‘IN PARADISUM’ Gregorian chant sung in English according to ‘MR3’ (Roman Missal, Third Edition). If anyone desires such a thing, feel free to download and print. Looking back, I wish I’d brought the TENOR and BASS voices into a unison (on B-Natural) for the word “welcome” on the second line.

    What does this mean? “Pre-Urbanite”
    Something informed critics have frequently praised vis-à-vis the Saint Jean de Brébeuf Hymnal is 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

“The Humanists abominated the rhythmical poetry of the Middle Ages from an exaggerated enthusiasm for ancient classical forms and meters. Hymnody then received its death blow as, on the revision of the Breviary under Pope Urban VIII, the medieval rhythmical hymns were forced into more classical forms by means of so-called corrections.”

— Father Clemens Blume, S.J.
