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.”

    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”).

    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.

    Pope Leo XIV on Sacred Music

Random Quote

The ratio of voices in modern choirs is usually wrong. Basses should be numerically greatest, then altos, then tenors, then sopranos. One good soprano can carry a high “A” against 30 lower voices.
