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.”

10 February 2021 • “Follow the text…”

Gregorian Chant does not follow the example of Baroque composers, who strongly emphasize (“slam”) the tonic accent. Cantus Gregorianus has a very sophisticated way of honoring the text—an approach which goes far beyond the “goo goo gah gah” approach of slamming the tonic accent. Thousands of examples in the Gregorian repertoire demonstrate this reality, but […]

5 February 2021 • “Tainted”

We have witnessed the downfall of so many “famous” Catholics—including priests—who had pretended to be holy, but were caught committing terrible sins. In a particular way, EWTN was harmed because several of their biggest stars were exposed. I was thinking about whether something holy can be “tainted,” and what that means. Fulton Sheen made mistakes, […]

3 February 2021 • “Politics”

A recent article—Glaring Omission from Post-Vatican II Lectionary—has generated enormous traffic, and has become one of our most popular articles. During that article, I made reference to our position on “political” articles. If anyone cares to know about my political views, please download: Only In Secret And With Horror. I have explained my views in […]

19 January 2021 • Confusion over feasts

For several months, we have discussed the complicated history of the various Christmas feasts: the Baptism of the Lord, the feast of the Holy Family, the Epiphany, and so forth. During a discussion, someone questioned my assertion that in some places Christmas had been part of the Epiphany. As time went on, of course, the […]

6 January 2021 • Anglicans on Plainsong

A book published by Anglicans in 1965 has this to say about Abbat Pothier’s Editio Vaticana, the musical edition reproduced by books such as the LIBER USUALIS (Solesmes Abbey): “No performing edition of the music of the Eucharistic Psalmody can afford to ignore the evidence of the current official edition of the Latin Graduale, which […]

2 January 2021 • Temptation

When I see idiotic statements made on the internet, I go nuts. When I see heretics promoted by people who should know better, I get angry. Learning to ignore such items is difficult—very difficult. I try to remember the words of Fr. Valentine Young: “Do what God places in front of you each day.” When […]

31 December 2020 • “COMITES CHRISTI”

The feasts for Saint Stephen Proto-Martyr (26 December), Saint John the Evangelist The Disciple Whom Jesus Loved (27 December), and the Feast of the Holy Innocents (28 December) seem untouched by any liturgical reforms. These are very powerful feasts—I believe they once possessed octaves—and I believe they could sometimes “overpower” a Sunday feast. The rules […]

23 December 2020 • A 5th? or 4th?

I have noticed that where the Editio Vaticana has a descending perfect fourth for the Gradual of Christmas Midnight Mass, many ancient manuscripts have a descending perfect fifth, which is pretty cool: Example A — Example B. The Vatican Edition is a CENTO, and never made any claim to be anything other than a CENTO. […]

“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 […]

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 […]

27 November 2020 • ACCENTS

Certain Latin words are constantly mispronounced. For example, Carl Orff’s Carmina Burana is supposed to be pronounced “Cármina” but people frequently pronounce it as “Carmína”—wrong! Another example: Nova organi harmonia is supposed to be pronounced “órgani” but many people erroneously say “orgáni.” A somewhat tricky word is incipit. In Latin, it would be “íncipit” while […]

20 November 2020 • Epiphany Sequence?

A very interesting Missale from 1759AD has a Sequence for the Epiphany, but I don’t know where one could find the musical notation. The Seqence is called: “Prompto Gentes Animo Ferte Nunc Altissimo Honorem Et Gloriam.”

18 November 2020 • FEEDBACK

From a priest in the Midwest: “That video by Andrea Leal which explains hymn meters and hymn text exchange is informative and a truly great explanation. Thank you for sending it to me. I hope all is well with you. God bless you as we soon enter into Advent.”

    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

“All those who take part in sacred music, as composers, organists, choir directors, singers, or musicians should above all give good example of Christian life to the rest of the faithful because they directly or indirectly participate in the sacred liturgy.”

— Directive issued under Pope Pius XII on 3 Sept. 1958
