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.”

19 January 2021 • Confusion over feasts

For several months, we have discussed the complicated history of the various Christmas feasts: the Baptism of the Lord, the feast of the Holy Family, the Epiphany, and so forth. During a discussion, someone questioned my assertion that in some places Christmas had been part of the Epiphany. As time went on, of course, the […]

A book published by Anglicans in 1965 has this to say about Abbat Pothier’s Editio Vaticana, the musical edition reproduced by books such as the LIBER USUALIS (Solesmes Abbey): “No performing edition of the music of the Eucharistic Psalmody can afford to ignore the evidence of the current official edition of the Latin Graduale, which […]

2 January 2021 • Temptation

When I see idiotic statements made on the internet, I go nuts. When I see heretics promoted by people who should know better, I get angry. Learning to ignore such items is difficult—very difficult. I try to remember the words of Fr. Valentine Young: “Do what God places in front of you each day.” When […]

31 December 2020 • “COMITES CHRISTI”

The feasts for Saint Stephen Proto-Martyr (26 December), Saint John the Evangelist The Disciple Whom Jesus Loved (27 December), and the Feast of the Holy Innocents (28 December) seem untouched by any liturgical reforms. These are very powerful feasts—I believe they once possessed octaves—and I believe they could sometimes “overpower” a Sunday feast. The rules […]

President’s Corner

    Music List • (2nd Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday—1 March 2026—the 2nd Sunday of Lent (Year A). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the flourishing feasts website alongside the official texts in Latin.
    —Jeff Ostrowski
    Particularly Beautiful
    The 2nd Sunday of Lent has magnificent propers. Its INTROIT is particularly striking—using a haunting tonality—but the COMMUNION with fauxbourdon verses is also quite remarkable. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.
    —Jeff Ostrowski
    Which Mass?
    In 1905, when the Vatican Commission on Gregorian Chant began publishing the EDITIO VATICANA—still the Church’s official edition— they assigned different Masses to different types of feasts. However, they were careful to add a note (which began with the words “Qualislibet cantus hujus Ordinarii…”) making clear “chants from one Mass may be used together with those from others.” Sadly, I sometimes worked for TLM priests who weren’t fluent in Latin. As a result, they stubbornly insisted Mass settings were ‘assigned’ to different feasts and seasons (which is false). To understand the great variety, one should examine the 1904 KYRIALE of Dr. Peter Wagner. One should also look through Dom Mocquereau’s Liber Usualis (1904), in which the Masses are all mixed up. For instance, Gloria II in his book ended up being moved to the ‘ad libitum’ appendix in the EDITIO VATICANA.

Quick Thoughts

    Extreme Unction
    Those who search Google for “CCCC MS 079” will discover high resolution images of a medieval Pontificale (“Cambridge, Corpus Christi College, MS 079”). One of the pages contains this absolutely gorgeous depiction of the Sacrament of Extreme Unction.
    —Corpus Christi Watershed
    PDF Chart • “Plainsong Rhythm”
    I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”
    —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.
    —Jeff Ostrowski

Random Quote

By far, the event that caused the biggest increase in requests for indults from the morning Mass requirement was the Second World War. The unusual requirements of providing Mass during wartime led to some unique legislation accommodating the time of Mass. Already in 1940, Pope Pius XII issued a motu proprio addressing the situation of holding Mass in countries where a “Black-out” had been ordered.
