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.”

Confusing Feasts of Christmas

Whether one considers the Missale Vetustum or the post-conciliar calendar—or even the 1908 calendar—the feasts which follow Christmas are very confusing. Last year I created this comparison chart. I hope you find it helpful. As far as I can tell, my chart is the first effort to carefully detail the changes made to post-Christmas feasts […]

1 January 2022 • Alternate Melodies

In a 14th century manuscript, I found some alternate melodies for the “Dóminus vobíscum” and “Et cum spíritu tuo.” I’m not sure we could ever use these at Mass; most priests have a hard enough time with the Editio Vaticana melodies!

Latin Mass • Conspicuous Snag in “Clarification”

“Benedictus” (Missa Iste Sanctus) • All voices recorded by Corrinne May

At Least This Is Clear!

Archbishop Roche, current head of the CDW, stated during his video interview as follows: “The Church has given us the celebration of the Mass in two forms. The Ordinary Form is the Mass that was developed under blessed Pope Paul VI in the 1960s. […] The Extraordinary Form is another expression, which is older than […]

“Communion Service” for the Extraordinary Form?

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, which is the 2nd Sunday of Lent (1 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has magnificent propers. Its somber INTROIT is particularly striking—using a haunting tonality—but the COMMUNION with its 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.

    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

“Rarely indeed,” asserted Pope Benedict XV (2 October 1921), “has the idealism of art and the glory of the faith been joined in such perfect harmony” as in the works of Palestrina and fellow polyphonists.

— Quoted by Gerard Ellard SJ (Church history professor at St. Mary’s College, KS)
