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.”

Message from the Vice-President!

The Vice-President of the Church Music Association of America, Dr. Horst Buchholz (who also serves as Director of Sacred Music for the Archdiocese of Detroit) sent us an email yesterday regarding the harmonizations (PDF) I composed for the Gregorian Chant psalm tones. Dr. Buchholz says: “Those settings are absolutely exquisite, as I’m used to when […]

Requesting Our Advent Eucharistic Hymn

A young lady named Agnes wrote to us: “Dear Mr. Ostrowski, do you have the PDF score for Ave Corpus Domini set to the ADVENT melody? Last year, we sang the hymn tune “Nun Komm der Heiden Heiland” quite a bit using your contrafactum technique. My choir appreciates the Latin hymns and practice videos, especially […]

Seven (7) Hymn Verses for November!

In the month of November, we remember in a special way the souls in purgatory. The BRÉBEUF HYMNAL often includes text alone versions for its hymns; why is that? The short answer is: flexibility. The “text only” version allows each choirmaster to employ a myriad of melodies. For example, I recently set the English translation […]

Jeff’s Attempt at Pipe Organ “Stops”

I’ve been attempting to record some Brébeuf hymns on the pipe organ, but I know very little about registration (“stops”). You can listen to this morning’s attempt, a recording of a tune called TRINITY COLLEGE. Do you know this tune? It’s quite nice. Feel free to email me vis-à-vis the registration I chose. To quickly […]

PDF • Morley’s Choral “Warm-Up”

For decades, I was against choral warm-ups. I felt they should be derived from repertoire—killing two birds with one stone—but was often too lazy to prepare such items. Over the years, I have taken a 180° turn. Now I’m a huge believer in vocal “warm-ups.” Our volunteer choir has been enjoying this wonderful warm-up exercise […]

Hymn • “Feast of Christ’s Kingship”

A wonderful text for the feast of Christ the King is: “Conquering Kings Their Titles Take.” We’re currently working on creating a professional recording. Until that’s complete, we’ve posted these preliminary versions. You might want to consider this hymn for the upcoming solemnity of Christ’s Kingship.

“Organ Interlude” (Dom Gregory Murray)

In my humble opinion, Dom Gregory Murray (d. 1992) was a splendid composer. Here’s my attempt to perform one of his INTERLUDES on the pipe organ. I’m not a “concert organist” so I deeply appreciate any feedback—especially about registration. By the way, you can download a fantastic collection of ORGAN INTERLUDES—all 104 pages completely free […]

    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.

    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

“The plan to definitively abolish the traditional Tridentine Mass … if it is true, seems to me to be an insult to the history of the Church and to Sacred Tradition, a diabolical project that seeks to break with the Church of Christ, the apostles, and the saints.”

— The Vatican’s chief liturgist (appointed by Pope Francis) from 2014-2021
