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.”

A Curious Rhythmic Detail in Tomorrow’s Jubilus

Occasionally the Solesmes rhythmic markings are surprising, as in one of tomorrow’s alleluias. Can we make sense of this?

Gregorian Chant • “Its True & Authentic Rhythm”

For this coming Sunday (Passion Sunday), there’s only one “MMV” singers must observe—and I placed a little arrow above it.

Seriously? • Bishop of Lexington Insists the Dominican Rite Never Existed (!)

These problematic assertions by Bishop Stowe will have to be withdrawn at some point.

The Responsa ad dubia and the Solesmes Chant Restoration

The early history of Solesmes plainchant research provides a historical parallel for responding to current Vatican liturgical rules.

The “Mora Vocis” • What is that?

The “Pre-NOH” editions have quite an idiosyncratic way of lengthening the neumes. • Fulsome illustrations are included examining and explaining the mora vocis of the Vatican edition; also mentioned is Dom André Mocquereau, Rafael Cardinal Merry del Val, and Pothier’s Liber Gradualis (1883)+

Are the Solesmes editions in conformity with the official edition?

Sigh … another day, another invisible “white note” to ignore!

    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.

    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

    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.
    —Jeff Ostrowski
    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.
    —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.
    —Jeff Ostrowski

Random Quote

“The Night Office—Nocturns or Matins—except for Holy Week, Easter Octave, and Christmas, has never appeared in the Vatican edition. The larger part of the mediaeval repertory for the Office thus remains still unpublished in the Vatican edition, and is likely to remain so, for the obvious reason that almost no cathedral chapters or monastic choirs sing the Night Office regularly today.”

— John Merle Boe (1968)
