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

    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.

    PDF Download • “Atténde Dómine”
    Although it isn’t nearly as ancient as other hymns in the plainsong repertoire, Atténde Dómine, et miserére, quía peccávimus tíbi (“Look down, O Lord, and have mercy, for we have sinned against Thee”) has become one of the most popular hymns for LENT—perhaps because it was included in the famous Liber Usualis of Solesmes. This musical score (PDF file) has an incredibly accurate version in English, as well as a nice version in Spanish, and also the original Latin. Although I don’t claim to have a great singing voice, this morning I recorded this rehearsal video.

    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

“One can still have silence even during the Canon, since one is not obliged to recite the Canon audibly at all times. A quieter, less powerful tone of voice will always permit an opportunity for personal, silent prayer.”

— Joseph Cardinal Frings (25-jan-1968), patron of “Consociatio Internationalis Musicae Sacrae” (papal church music association)
