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.”

“Stowe Missal Eucharistic Motets” • For 3 Voices

PDF Download • Trinity Sunday (22 pages)

Composing Your Own Antiphons?

In the days before Vatican II, dioceses had their own special feast days.

10 June 2022 • “Official” rhythm of plainsong

I continue to search for the most beautiful way to present the “pure” Editio Vaticana scores. (Technically, the “pure” rhythm of the official edition is what everyone is supposed to use.) You can download my latest attempt, which is the Introit for this coming Sunday: Feast of the Most Holy Trinity. Because this is not […]

New Release! • “Missa de Beata Virgine” (Kevin Allen)

As singers performed this Kevin Allen piece, they wept—but crying is bad for singing technique!

“An Unknown Parishioner Approached Me…”

Can modern composers write hymns? Are they stirring?

PDF Download • (Organ Accompaniment)

I created this organ accompaniment booklet for organists who will accompany Vespers on Pentecost Sunday. Feel free to download it; it might give you some ideas or inspiration. Be warned: It looks pretty sloppy. (The organist is the only one who sees it.)

Revelation • “Re: The Official Rhythm”

A very intelligent singer admitted that only yesterday did he finally come to understand what a “melismatic mora vocis” is. Only yesterday did he come to understand the “white notes” (blank spaces). You can see the Introit for Pentecost Sunday only has two instances of MMV (“melismatic mora vocis”).

28 May 2022 • “Pristine” Vatican Rhythm

My choirs have been singing from the “pure” Editio Vaticana rhythm, which is (technically) the official rhythm of the Catholic Church. I haven’t quite decided how I want the scores to look yet, but this one I’ve produced for tomorrow, Dominica Post Ascensionem (“Sunday after the Ascension”).

    PDF • “Music List” (Sunday, 11 January)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for Feast of the Baptism of the Lord (SUNDAY, 11 January 2025). If such a thing interests you, feel free to download it as a PDF file. The FAUXBOURDON verses for the Communion Antiphon—to say nothing of the antiphon itself—are breathtaking. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the monumental feasts website alongside the official texts in Latin.
    —Jeff Ostrowski
    Epiphany Hymn • “New 2-Voice Arrangement”
    The Von Trapp Family Singers loved a melody that was featured heavily (perhaps even “too heavily”) in the Brébeuf Hymnal. It goes by many names, including ALTONA, VOM HIMMEL HOCH, and ERFURT. If you only have one man and one woman singing, you will want to download this arrangement for two voices. It really is a marvelous tune—and it’s especially fitting during the season of Christmas and Epiphany.
    —Jeff Ostrowski
    Simplified Accompaniment (Epiphany Hymn)
    About a month ago, I created a simplified keyboard accompaniment for “Come, Thou Long-Expected Jesus”—the famous ADVENT hymn—using a melody called CROSS OF JESUS. It was soon downloaded more than 1,000 times. As of this morning, you can download a simplified keyboard accompaniment for the belovèd Epiphany hymn “Bethlehem! Of noblest cities” (O Sola Magnarum Urbium) by clicking on this link (PDF file). Many organists are forced to serve simultaneously as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult, which explains why choirmasters appreciate these simplified keyboard accompaniments.

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

“In case of urgent danger of life anyone may baptize, even a heretic or pagan. It is sufficient that he administer the essential matter and form and have the implicit intention of doing what Christ instituted. Naturally a Catholic must be preferred, if possible. A man is preferred to a woman; but anyone else to the parents.”

— Father Adrian Fortescue (1917)
