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.”

PDF • Morley’s Choral “Warm-Up”

For decades, I was against choral warm-ups. I felt they should be derived from repertoire—killing two birds with one stone—but was often too lazy to prepare such items. Over the years, I have taken a 180° turn. Now I’m a huge believer in vocal “warm-ups.” Our volunteer choir has been enjoying this wonderful warm-up exercise […]

Hymn • “Feast of Christ’s Kingship”

A wonderful text for the feast of Christ the King is: “Conquering Kings Their Titles Take.” We’re currently working on creating a professional recording. Until that’s complete, we’ve posted these preliminary versions. You might want to consider this hymn for the upcoming solemnity of Christ’s Kingship.

“Organ Interlude” (Dom Gregory Murray)

In my humble opinion, Dom Gregory Murray (d. 1992) was a splendid composer. Here’s my attempt to perform one of his INTERLUDES on the pipe organ. I’m not a “concert organist” so I deeply appreciate any feedback—especially about registration. By the way, you can download a fantastic collection of ORGAN INTERLUDES—all 104 pages completely free […]

1950s Mandatory Military Service? Huh?

I would be very curious to know what readers think about this claim made by Patrick J. Buchanan. He says military service in the 1950s was obligatory in the United States. Is this true? Let me know your thoughts by scrolling to the bottom of this page, where an email address is provided. Patrick J. […]

“No Fourth Sunday of Advent” (EF)

In the Extraordinary Form (“Missale Vetustum”) because Christmas falls on a Monday in 2023, the Vigil of the Nativity of Our Lord takes precedence over the Fourth Sunday of Advent. This usually only happens about every six years or so. I will miss the 4th Sunday of Advent, but the VIGIL Mass is also quite […]

When just 13 years old, Beethoven……

Bach’s Well-Tempered Clavier (WTC) was not officially published until 1801. By that time, many hand-copied manuscripts had circulated through Europe. According to Charles Rosen: “Beethoven, at the age of 13, played the entire WTC in public.” His feat was published in the newspapers of that time. In my view, both books of the WTC—with a […]

Dissonant Chord? • (not in context)

If you play nothing but the notes and chord highlighted by yellow in this passage from the “Haec Dies” Gradual, it’s quite ugly and dissonant. However, in the context of the stepwise descending bass-line, the LEMMENSINSTITUUT does not disappoint!

    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.”

    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.

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.”

    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

[on Latin] “No change in Mass: people have missals and can read. More vernacular can be useful in the Sacraments: Baptism, Confirmation, Extreme Unction, Matrimony.”

— Cardinal Spellman (one of the Vatican II fathers)
