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.”

“Palestrina500” • Sacred Heart Parish (Michigan)

Jean Calvin (d. 1564) famously detested sacred music. Ironically, Jonathan Bading—a convert from Calvinism!—has become one of the Church’s “leading lights” when it comes to authentic church music.

Offered in a Spirit of Dialogue

Pope Francis said famously: “To dialogue entails a cordial reception, not a prior condemnation.” The following brief utterances of mine are offered in that spirit. Pope Saint Pius X called the sacred liturgy “the primary and indispensable source of the true Christian spirit.” If the reformers had told the fathers of Vatican II they desired […]

Polyphony For Three Voices!

Writing excellent music is easier in four voices than three. We often sing from MATRI DIVINAE GRATIAE, a 3-voice collection by Kevin Allen for Soprano, Alto, and Bass. Someone made a recording of my volunteer choir singing “Si Ambulávero” (from that collection). This “raw recording” starts toward the end of the psalm tone then launches […]

“Ite, Missa Est” • What Does That Actually Mean?

Bishop Ambo’s assertion that Mass was attended—for centuries—by a single woman (and nobody else) is bizarre.

PDF Download • “Chant Chart”

A thoughtful priest from another country wrote me a magnificent message praising a PDF comparison chart I recently posted. It deals with “staffless” CARMEN GREGORIANUM (Gregorian Chant). Download it for free by scrolling to the bottom of this article. Of course, I hope you will read the article instead of just scrolling past it.

“Somber Song!” • Sexagesima Sunday

As we approach the holy season of Lent, the prayers and readings become more lengthy. When we arrive at Easter, the prayers and readings will become extremely brief. As we get closer to Lent, some of the music becomes quite somber. I can’t think of a more somber piece than the INTROIT for Sexagesima Sunday. […]

    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.”

    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

“We must acknowledge that We have been somewhat disturbed and saddened by these requests. One may well wonder what the origin is of this new way of thinking and this sudden dislike for the past.” [Paul VI responding to requests from monks asking permission to remove Latin from the Divine Office.]
