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.”

An Interview on Mocquereau’s Method

I recently appeared on Square Notes, the Sacred Music Podcast to discuss some of the basics of Dom Mocquereau’s system of Gregorian rhythm. It’s impossible to give a full treatment to such a complex topic in a mere forty minutes, but I touched on a lot of the foundational ideas, with especial emphasis on the […]

Do We Need a Beautiful Cento, or an Archaic Reversion?

The Vatican Edition, as well as St. Gregory’s work were both a Cento built on tradition to unify the Church. Semiological editions are archaic reversions. A close look at the Puer Natus Est in both forms is offered.

“Our hymnbooks know nothing of such a treasure as this, and give us pages of poor sentiment in doggerel lines by some tenth-rate modern versifier.” —Father Fortescue

It seems to me that our responsibility of teaching the Faith through music is much more serious than is commonly perceived.

Three-Voice Piece You’ll Love!

To help my volunteer choir members learn, I have attempted to record all the vocal parts for Justorum Animae, composed for SOPRANO, ALTO, and BASS. It’s from a brilliant collection by Kevin Allen called Matri Divinae Gratiae. You can hear my attempt by visiting this website and scrolling down to “Justorum Animæ.” My singers really […]

    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.
    —Jeff Ostrowski
    “To Cover Sin With Smooth Names”
    Monsignor Ronald Knox created several English translations of the PSALTER at the request of the Cardinal Archbishop of Westminster. Readers know that the third edition of the Saint Edmund Campion Missal uses a magnificent translation of the ROMAN CANON (and complete Ordo Missae) created in 1950 by Monsignor Knox. What’s interesting is that, when psalms are used as part of the Ordo Missae, he doesn’t simply copy and paste from his other translations. Consider the beautiful turn of phrase he adds to Psalm 140 (which the celebrant prays as he incenses crucifix, relics, and altar): “Lord, set a guard on my mouth, a barrier to fence in my lips, lest my heart turn to thoughts of evil, to cover sin with smooth names.” The 3rd edition of the CAMPION MISSAL is sleek; it fits easily in one’s hand. The print quality is beyond gorgeous. One must see it to believe it! You owe it to yourself—at a minimum—to examine these sample pages from the full-color section.

    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.”

    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

It is clear the Church is facing a grave crisis. Under the name of “the new Church” and “the post-conciliar Church,” a different Church from that of Jesus Christ is now trying to establish itself: an anthropocentric society threatened with imminent apostasy which is allowing itself to be swept along in a movement of general abdication under the pretext of renewal, ecumenicism, or adaptation.

— Cardinal Henri de Lubac (29 August 1967)
