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.”

Problems Encountered Teaching Rhythms

Well, today I decided to buck the system (in spite of my general LOVE of tradition) and simply referred to the various notes by their Takadimi syllables.

The Current Heresy

He was right, I spoke an unforgivable heresy—boys and girls are different.

Give Yourself a Boost in the New Choral Year

The grandmother of 5 choristers informed me that one of her granddaughters told her rehearsal wasn’t long enough—it seemed to be over just as it was starting!

Let’s face facts—the English cathedral system of forming church musicians works.

The Musical Power of the Priest in the Ordinary Form

One musical advantage for the priest celebrating the Ordinary Form is that he can play an active role leading the music, yet still celebrate Mass.

Ad Orientem and Sacred Music

Father told me that he felt extremely awkward standing in the sanctuary for two minutes while the congregation did nothing but look at him.

Sing the Mass

Whether your particular parishes are rich or poor, big or small, love sacred music or hate it, there is one thing that I challenge all of you to do, and that is to sing the Mass.

Do My Eyes Deceive Me?

I’ve often told my choir members that before I die they will be singing from music displayed on some form of a tablet, but I never thought I’d see the Capella Sistina blazing the trail!

Dr. Lucas Tappan · June 28, 2016

Theology and Music

I hope and pray the Church continues to raise up true artists who will bring the Gospel to the world through the greatest of all the Church’s arts—Music.

The Theology of the Organ

Let’s put the organ back on the pedestal it rightfully deserves.

    PDF • “Cantus Mariales” (192 pages)
    Andrea Leal has posted an absolutely pristine scan of CANTUS MARIALES (192 pages) which can be downloaded as a PDF file. To access this treasure, navigate to the frabjous article Andrea posted Monday. The file is being offered completely free of charge. The beginning pages of the book have something not to be missed: viz. a letter from Pope Saint Pius X to Dom Pothier, in which the pope calls Abbat Pothier “a man versed above all others in the science of liturgy, and to whom the cause of Gregorian chant is greatly indebted.”
    —Jeff Ostrowski
    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.
    —Jeff Ostrowski
    Like! Like! Like!
    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.

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.
    —Jeff Ostrowski

Random Quote

“Whether celebrated with priest and people facing each other or with priest and people together facing the same direction, every Eucharist is Christ coming to meet us, gracing us with a share in his own divine life.”

— Most Rev’d Arthur J. Serratelli (1 December 2016)
