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.”

    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.

    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.
    —Jeff Ostrowski
    PDF • Our Lady of Guadalupe (12 Dec.)
    The Responsorial Psalm may be downloaded as a PDF file (organist & vocalist) for 12 December, which is the Feast of Our Lady of Guadalupe. When it comes to the formulary for this Mass, it’s astounding how infrequently it’s included in official books. Prior to Vatican II, one had to search through “supplemental material” printed in the back of hand-missals and graduals. But since 1970, the feast is virtually nonexistent. According to the UNIVERSAL KALENDAR, 12 December is the “Feast of Saint Jane Frances De Chantal, Religious” (Die 12 decembris: S. Ioannæ Franciscæ de Chantal, religiosæ). Why should that feast overpower Our Lady of Guadalupe? In the United States, OLG is celebrated—and I’d assume in Mexico, Central America, South America, and Canada—but, as I said, the Propria Missae are virtually impossible to locate. I possess only three books which mention this feast.

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.
    —Jeff Ostrowski
    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

“In all this mediaeval religious poetry there is much that we could not use now. Many of the hymns are quite bad, many are frigid compositions containing futile tricks, puns, misinterpreted quotations of Scripture, and twisted concepts, whose only point is their twist. But there is an amazing amount of beautiful poetry that we could still use. If we are to have vernacular hymns at all, why do we not have translations of the old ones?”

— Fr. Adrian Fortescue (d. 1923)
