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.”

Myth Re: Johann Sebastian Bach

Some musicologists try to make a “splash” by saying that Bach was totally forgotten when he died—remembered only as an organ virtuoso—and that his sons were more famous than he was. Such an idea is indefensible. It is true that musical styles changed in 1750AD—but this is normal. Musical styles change constantly; e.g. much of […]

Arthur Friedheim, Franz Liszt’s Secretary

Arthur Friedheim (d. 1932) has a very poor reputation as a pianist, and Liszt rejected him several times before finally accepting him as a pupil, yet the Liszt recordings he left are quite good—especially considering the transgressions by other Liszt pupils. Friedheim must have been an amazing musician; twice he was asked to become conductor […]

Consilium document (“Instantibus Pluribus”) to presidents of the national liturgical commissions, on norms for translation of the Graduale Simplex, dated 23 January 1968: “The types of chant in the Graduale Simplex may be adapted to the style of music and song typical of individual peoples. But any sort of secular or profane melody is excluded.”

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.

    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

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)
