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.”

Shameful Quote

Some feel the most irresponsible 1960s reformer was Fr. Godfrey Diekmann. The Second Vatican Council had solemnly declared: “In accordance with the centuries-old tradition of the Latin rite, the Latin language is to be retained by clerics in the divine office.” In spite of this clear directive, Diekmann (3 March 1964) wrote: “What young candidate […]

As of a few minutes ago, you may go here to download the organ accompaniment booklet (25 pages) I created for the feast of the TRANSFIGURATION.

Summer Singers’ Repertoire!

I mentioned a 3-Voice Setting of the AGNUS DEI, based on a Canon by William Byrd (d. 1623) in the context of the “hairpin” technique, something I really will emphasize this coming season. The piece is for Soprano, Middle, and Baritone. (The “Middle” voice should ideally be a mixture of women and men.) Recently, we […]

    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

Goupil deserves the name of martyr not only because he has been murdered by the enemies of God and His Church while laboring in ardent charity for his neighbor, but most of all because he was killed for being at prayer and notably for making the Sign of the Cross.

— St. Isaac Jogues (after the martyrdom of Saint René Goupil)
