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.”

“Blessing the Bell” • Most Rev’d Alejandro D. Aclan

When a monk hears the bell, he stops whatever he’s doing and immediately goes to prayer. It is the voice of God calling us to pray, to avoid sin, and to forget the things of this world and think of Him.

“Rorate Mass” (FSSP) • 12 December 2020

Attendance was standing room only. Afterwards, the children presented roses to Mary—as the entire parish prayed the Rosary—and then we consecrated California to Jesus Christ.

“Homily — 3rd Sunday of Advent, Year B” • Father Valentine Young, OFM

As the Gloria during Mass suggests, we should “thank Him simply because of His great glory.” When is the last time you did that?

“Martinelli’s Letter” (dated 18 February 1910)

My recent post on the repercussion has induced some to ask: “Can we just sing whatever rhythm we want for the Vatican Edition? What about mensuralism? What about Bonvin and Vollaerts?” For those of us who work in the Extraordinary Form, we must follow the rhythm of the Editio Vaticana, and this was addressed in […]

9 December 2020 • A Cool Tradition

Before the reforms of the “Code of Rubrics” (1961), antiphons at Vespers were abbreviated in a cool way. For example, look at this antiphon, Ecce Veniet (from Vespers on the 4th Sunday of Advent). But that tradition—as far as I know—ended in 1961, with §191 which said: “The whole antiphon is always said before and […]

Book Title • “English As She Is Spoke”

One who translates Aquinas expects to be cross-examined by those who understand philosophy and Latin; but Bible translators are liable to be cross-examined by anybody, because everybody thinks he knows what the Bible means.

30 November 2020 • “Case in point”

The Solesmes rhythmic markings, which often contradict the official rhythm, do such damage to the antiphons of the Divine Office that—in my humble opinion—they should be abandoned. (In reality, this will never happen.) But sometimes, they do great damage to the melody of the Graduale Romanum, and I would offer the Offertory for the 1st […]

President’s Corner

    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.

    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.

    Which Mass?
    In 1905, when the Vatican Commission on Gregorian Chant began publishing the EDITIO VATICANA—still the Church’s official edition— they assigned different Masses to different types of feasts. However, they were careful to add a note (which began with the words “Qualislibet cantus hujus Ordinarii…”) making clear “chants from one Mass may be used together with those from others.” Sadly, I sometimes worked for TLM priests who weren’t fluent in Latin. As a result, they stubbornly insisted Mass settings were ‘assigned’ to different feasts and seasons (which is false). To understand the great variety, one should examine the 1904 KYRIALE of Dr. Peter Wagner. One should also look through Dom Mocquereau’s Liber Usualis (1904), in which the Masses are all mixed up. For instance, Gloria II in his book ended up being moved to the ‘ad libitum’ appendix in the EDITIO VATICANA.

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.

Random Quote

“Naturally the accompaniment of the organ is merely tolerated during the office of the dead, but in fact, in nearly every parish this toleration has become a habit.”

— Henri Potiron, 1958
