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.”

“Mixing” Your Singers? • Just Do It!

Not long ago, I posted an Agnus Dei for Three Voices by William Byrd (d. 1623). When we sing the “Agnus Dei” at Mass, I often have the singers mix up, so they’re not standing next to someone singing their part. In my experience, this technique does wonders for tuning. Here’s a live excerpt (Mp3) […]

8 Sept. 2023 • Charles Rosen on Bach!

Charles Rosen was a concert pianist who published insightful books about various musical topics. I believe our readers will enjoy this 27-minute presentation on the music of Johann Sebastian Bach. Not everything Mr. Rosen says is true. (For instance, Rosen was not the first pianist to record the ART OF THE FUGUE on the piano. […]

7 Sept. 2023 • Alphabetized Hymnals?

One could be forgiven for believing that arranging hymns in alphabetical order would make them easier to find. Believe it or not, that’s actually one of the worst decisions an editor could make. This very brief video explains why.

27 August 2023 • Nine Merry Men!

Half a decade has passed since nine (9) colleagues from Corpus Christi Watershed contributed texts, melodies, and harmonizations to a special hymn book in honor of North America’s patron saint, Father John Brébeuf. The website promoting it was massively overdue for a facelift. As of a few minutes ago, I can report that it’s been […]

From a female choirmaster: “Thank you for your recent article, Jeff. We here in _____ absolutely love our Brébeuf hymnals! They have saved my life as a choir director! ☺️ The ease with which my choir members plunge into a new hymn using the ‘common melodies technique’ is so wonderful. You can see the relief on […]

    2-Voice Arrangement for Lent
    Those seeking a two-voice arrangement for LENT and PASSIONTIDE should click here and scroll down. It’s based on number 775 in the Brébeuf Hymnal, with an enchanting melody written by Kevin Allen (the legendary American composer of sacred music). That text—“Pendens In Crucis Cornibus”—is often used for the Feast of our Lady of Sorrows. That link is important because, in addition to the musical score, it provides free rehearsal videos for each individual voice: something volunteer choirs appreciate!

    “Sanctus VIII” • Organ Accompaniment
    A few days ago, I composed this organ harmonization for SANCTUS VIII. This Mass is traditionally called Missa de ángelis or “Mass of the angels.” In French, it is Messe de Anges. You can evaluate my attempt to simultaneously accompany myself on the pipe organ (click here) while singing the melody. My parish is currently singing this setting.

    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.

    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

“In case of urgent danger of life anyone may baptize, even a heretic or pagan. It is sufficient that he administer the essential matter and form and have the implicit intention of doing what Christ instituted. Naturally a Catholic must be preferred, if possible. A man is preferred to a woman; but anyone else to the parents.”

— Father Adrian Fortescue (1917)
