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.”

Your Christmas Present!

Jeff Ostrowski · December 24, 2017

90902 CCW present E RECENTLY launched a special fundraising drive, and promised to release certain items if we met our goal. Thanks to your generosity, we succeeded; so below are the files we promised. Of course the money is important—because it allows us to survive—but on a level you might not realize, the fundraising also gives encouragement. It demonstrates that our efforts matter enough to readers that they’ll donate (and church musicians are not wealthy). We enjoyed reading the little “notes” you sent in with your pledges, even the electronic ones.

When our contributors get discouraged, I always say the same thing: “Remember we are trying to do something positive. This is not easy; and the proof is how few Catholic websites are positive vs. how many Catholic websites consist of negativity, gossip, and scandal.”

Merry Christmas!

    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.

    You won’t believe who recently gave us a “like” on the Corpus Christi Watershed FACEBOOK PAGE. Click here (PDF) to see who it was. We were not only sincerely honored, we were utterly flabbergasted. This was truly a resounding endorsement and unmistakable stamp of approval.

    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.

    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.

Random Quote

“To me it is a most inspiring reflection that, while empires and kingdoms have tumbled down, while language and custom of every kind have changed beyond recognition, still day by day the humblest Catholic priest in the remotest mission stands at his altar dressed in the garb of old Rome.”

— Father Adrian Fortescue (8 February 1912)
