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 • “Organ Interludes” (Manuals Only)

In graduate school, one is taught a valuable lesson: if you emphasize everything, nothing is emphasized. In other words, putting every other word in bold or italic (or both) wrecks your paper. I never to use the word “best”—but today I make an exception. The book of organ interludes released today by my colleague is […]

For the Upcoming Choir Season!

Last week, I posted an SATB choral setting of the SANCTUS in a ‘contemporary’ style. You might want to consider this piece for two reasons: (1) It’s extremely brief; (2) Free rehearsal videos are available for each individual part. The piece is by Father Lhoumeau.

PDF Download • “Sunday Vespers” (22 pages)

In spite of its imperfections, creating this (draft) booklet required much more effort than I had anticipated.

11 July 2022 • FEEDBACK

Someone who heard the CCW plainsong recordings with NOH accompaniment says: “For years I have travelled the continents and crossed the oceans of Gregorian chant in search of a composition and interpretation as sublime as this. The text and the melody are interwoven in a game of mirrors with the interpreters, the singer and the […]

Gregorian Chant • Its “True” Rhythm

I’m dumbstruck (with joy) to see that my recent video presentation on plainsong rhythm has garnered quite a number of “views” on VIMEO. I also made the full presentation available on YouTube, and—as I write these words—it has collected 700+ views. How cool is it that folks are still interested in the rhythm of Cantus […]

Across the Pacific • Alto is “Raving”

From Asia: “I held choir rehearsal yesterday and one of the choir members (singing Alto) was just raving about how she loved the layout of the Brébeuf Choral Supplement because she didn’t have to look up and down for both music and verse—and she loved the ease with which she could sing her part because […]

Alabama Assessment!

We received this evaluation of Symposium 2022 from an Alabama participant: “Oh, how the Symposium echoed the words of Cardinal Merry Del Val: …choosing only what is most conformed to Thy glory, which is my final aim. In one short and fast paced week, the faculty and attendees showed me the hand of God and […]

PDF Download • Trinity Sunday (22 pages)

Feel free to download this Organ Accompaniment Booklet for Trinity Sunday (Second Vespers). Notice how the modes progress by number. Psalm 1 is mode 1; Psalm 2 is mode 2; Psalm 3 is mode 3; Psalm 4 is mode 4; Psalm 5 is mode 5. I am told by an expert that other feasts (such […]

10 June 2022 • “Official” rhythm of plainsong

I continue to search for the most beautiful way to present the “pure” Editio Vaticana scores. (Technically, the “pure” rhythm of the official edition is what everyone is supposed to use.) You can download my latest attempt, which is the Introit for this coming Sunday: Feast of the Most Holy Trinity. Because this is not […]

7 June 2022 • FEEDBACK

From Chelan, Washington: “CCWatershed is a God-sent resource that I can’t function without! Such great work by the team to bring beauty back to our liturgy!” From Gainesville, Florida: “I am so appreciative of the work, of my brothers and sisters in music!” From Troutman, North Carolina: “Keep up the excellent work in service of the Liturgy!”

PDF Download • (Organ Accompaniment)

I created this organ accompaniment booklet for organists who will accompany Vespers on Pentecost Sunday. Feel free to download it; it might give you some ideas or inspiration. Be warned: It looks pretty sloppy. (The organist is the only one who sees it.)

Revelation • “Re: The Official Rhythm”

A very intelligent singer admitted that only yesterday did he finally come to understand what a “melismatic mora vocis” is. Only yesterday did he come to understand the “white notes” (blank spaces). You can see the Introit for Pentecost Sunday only has two instances of MMV (“melismatic mora vocis”).

3 June 2022 • FEEDBACK

From Saint Petersburg, Florida: “Thank you so much for all of your tireless and selfless work in building up the Kingdom of God and Helping us on the path toward heaven! Your work for many years now has borne much fruit in my life and in the lives of whom I work with. May the […]

1 June 2022 • FEEDBACK

From Pennsylvania: “Thank you for all of the music on your website! It has been of immense help to me as a choir director.” From Minnesota: “Thank you for your awesome ministry! I started going to a Latin mass parish about 10 years ago, and this website has been indispensable to me. I could not […]

    Music List • (5th Sund. Ordinary Time)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for this coming Sunday, 8 February 2026, which is the 5th Sunday in Ordinary Time (Year A). If such a thing interests you, feel free to download it as a PDF file. You will probably notice it isn’t as ‘complete’ or ‘spiffy’ as usual, owing to some difficulties which took place this week.
    —Jeff Ostrowski
    PDF • “Communion” (5th Sunday in Ordin.)
    The COMMUNION ANTIPHON for this coming Sunday, 8 February 2026—which is the 5th Sunday in Ordinary Time (Year A)—is truly delightful. You can download the musical score completely free of charge. This text will be familiar to altar boys, because it’s PSALM 42. The Feder Missal makes the following claim about that psalm: “A hymn of a temple musician from Jerusalem: he is an exile in a heathen land, and he longs for the holy city and his ministry in the Temple there. The Church makes his words her own.”
    —Jeff Ostrowski
    Funeral Music “Template” • For Families
    Many have requested the MUSICAL TEMPLATE for funerals we give to families at our parish. The family of the deceased is usually involved in selecting Number 12 on that sheet. This template was difficult to assemble, because the “Ordo Exsequiarum” has never been translated into English, and the assigned chants and hymns are given in different liturgical books (Lectionary, Gradual, Order of Christian Funerals, and so on). Please notify me if you spot errors or broken links. Readers will be particularly interested in some of the plainsong musical settings, which are truly haunting in their beauty.

We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. It couldn’t be easier to subscribe!

    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

“How on earth in the [post-conciliar] liturgy for the dead should there be no more mention of sin and expiation? There’s a complete absence of imploring the Lord’s mercy. […] Although the texts were beautiful they were still lacking in the sense of sin and the sense of mercy. But we need this! And when my final hour comes, ask for mercy for me from the Lord, because I have such need of it!”

— Pope Saint Paul VI (3 June 1971)
