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 God We Cannot “See”

By the Incarnation, our Savior’s divinity was hidden. In the Eucharist, according to Saint Thomas Aquinas, our Savior also ‘hides’ His manhood. We cannot see God—although we can see Him (through faith) in the SANCTISSIMUM, in the eyes of the poor, in the grandeur of the mountains, and so forth. Hymn #746 in the Brébeuf […]

This Coming Sunday’s Introit

You can evaluate my attempt to record this Sunday’s INTROIT according to the official rhythm of the Catholic Church. This INTROIT is very well known because it’s repeated over and over at the end of the year, depending on how many Sundays after Pentecost occur in a particular year.

“Christ the King” • Introit

I have attempted to record the Introit for the Feast of Christ the King according to the official rhythm of the Catholic Church. You can view the YouTube recording of my attempt. Traditionally, our Savior’s “kingship” was celebrated as part of the Epiphany—but in 1925, Pope Pius XI created the “feast of Christ the King” […]

PDF Download • Plainchant on 5 lines!

I can’t think of better way to learn Gregorian chant than to download this 651-page PDF file, containing the marvelous Gregorian Vesperale (1915) by Father Karl Weinmann (d. 1929) printed on five lines. If you accompany Vespers directly from the plainsong notation, this makes life easy! It’s also fun to compare the Gregorian chant inside […]

    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.

    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.

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

“As often as possible they gathered together the children of the village and sat them down in the cabin. Father Brébeuf would put on a surplice and biretta and chant the Our Father, which Father Daniel had translated into Huron rhymes, and the children would chant it after him. Next, he taught them the sign of the cross, the Hail Mary, the Apostles’ Creed, and the Commandments.”
