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.”

PDF Download • ‘Choral Extension’ for the Sanctus (especially useful in the Ordinary Form)

It’d be easier to accept if they admitted they were explicitly contradicting Vatican II … but instead, they lied egregiously.

    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.

    Psalm Tone Challenge!
    Many readers know that Tone 1a3 is the most difficult PSALM TONE in the 1962 books (and isn’t called for very often). But what about very short verses—which is the absolute most concise you know? The shortest PSALM TONE segment I know would be the fourth verse (PDF) from Psalm 44, used during Matins at Christmas. It’s literally one word long. If you know a more minuscule one, please email me!
    —Jeff Ostrowski
    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.

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

On 26 July 1916—during the German occupation of Belgium—a student choir led by Van Nuffel performed his setting of the psalm “Super flumina Babylonis” in Saint Rumbold’s Cathedral. The text and the musical setting very aptly expressed the depressed and rebellious mood of the population. The acclaim was enormous, and it laid the foundation for Van Nuffel’s formation of the Saint Rumbold’s choir.
