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.”

ARDINAL BARTOLUCCI was challenged (in 2008) vis-à-vis whether the pre-conciliar rites were “participatory.” He responded forcefully, citing a little town “in this beautiful countryside, at one time inhabited by people full of faith and piety. On Sunday at Vespers the priest would have been able to intone the Deus in adjutórium meum inténde and then fall asleep in the high-backed chair—not waking up until the CHAPTER—and the peasants would have continued on their own—and the heads of family would have intoned the antiphon!”

Our Lady of Guadalupe: Feel free to download this booklet I created for December 12th—“Feast of Our Lady of Guadalupe”—which in Mexico replaces the 3rd Sunday of Advent. For the Missale Antiquius, Our Lady of Guadalupe was a Double of the First Class in San Francisco, Santa Fe, Sacramento, Tucson, and Los Angeles.

The organ accompaniment I created is pretty messy, but feel free to download it.

A False Claim :

Latin Mass parishes are falsely accused of “not following Vatican II.” How long will such a bizarre accusation be allowed? We recently saw that Bishop Robert E. Guglielmone issued a document explicitly contradicting Vatican II. He justified this by saying we must “follow” the Second Vatican Council. Does “following the Council” mean doing the exact opposite of what Vatican II specifically mandated? In what universe does that make sense? Here’s a quick reminder:

Vatican II said:
“Pastors of souls should see to it that the chief hours, especially Vespers, are celebrated in common in church on Sundays and the more solemn feasts. And the laity, too, are encouraged to recite the divine office, either with the priests, or among themselves, or even individually” (SC §100).

Vatican II said:
“Lauds and Vespers are the two hinges on which the daily office turns” (SC §89a).

Vatican II said:
“The Latin language is to be retained by clerics in the divine office” (SC §101).

You can watch a YouTube Video (with scrolling score) showing our congregation singing Vespers.

A Digression: In my Vespers booklet above, perhaps you noticed I sometimes ignore the episemata of the Classical Solesmes Method. If you’ve been following this blog for any length of time, you already know that I have all kinds of issues with adding such editorial “suggestions” (!) to the official edition, and Abbat Pothier was correct to point out that rarely do they reflect the Romanian signs accurately. Speaking of melismatic moræ vocis, those familiar with Gregorian Chant will have noticed some strange figurations in the “Ave Maria” from the 3rd Sunday of Advent. For instance, these two notes are supposed to form a “long note” according to the Classical Solesmes Method, but they’re too far apart for that:

In the Editio Vaticana—which is still the official edition of the Church—there is a “melismatic mora” there, which means there is supposed to be a “pause” (slight elongation) at the end of that neume:

This is the only example I know of where Dom Mocquereau changed or modified something significant in a subsequent edition, because you can see that the 1908 Solesmes edition does mark that melismatic mora:

A Case In Point: It would seem that Solesmes Abbey got a little “bolder” when it came to disobeying the Vatican after their 1908 edition met with success! By the way, the aforementioned Offertory (“Ave María”) is a perfect example of Solesmes contradicting the official edition in tons of places:

    PDF Download • “Organ Accompaniment”
    Over the past few years, I’ve been harmonizing all the vernacular plainsong Introit settings by the CHAUMONOT COMPOSERS GROUP. This coming Sunday—10 May 2026—is the 6th Sunday of Easter (Year A). The following declaration will probably smack of “blowing my own horn.” However, I’d rank this accompaniment as my best yet. In this rehearsal video, I attempt to sing it while simultaneously accompanying myself on the pipe organ. The musical score [for singers] as well as my organ accompaniment can be downloaded free of charge from the flourishing feasts website.

    “Gregorian Chant Quiz” • 4 May 2026
    A few days ago, the CORPUS CHRISTI WATERSHED Facebook page posted this Gregorian Chant quiz regarding a rubric for the SEQUENCE for the feast of Corpus Christi: “Lauda Sion Salvatórem.” There is no audience more intelligent than ours—yet surprisingly nobody has been able to guess the rubric. Drop me an email with the right answer, and I’ll affirm your brilliance to everyone I encounter!

    “Rare Photographs” • Hannibal Bugnini
    On 2 September 2025, we included in this article extremely rare photographs of Archbishop Hannibal Bugnini taken in Iran circa 1979. Bugnini had initially been banished by the pope to Uruguay, but he refused to obey. [This is interesting, since Bugnini relied upon ‘blind obedience’ when it came to modifications of the ancient liturgy.] After he refused to obey the order from the pope, Hannibal Bugnini was banished to Iran. You can also watch a short video of Hannibal Bugnini in Iran, dated 10 November 1979. That’s about a week after the USA embassy hostage crisis began in Tehran, and Pope Saint John Paul II had sent the leader of the Iranian Revolution a special letter.

    Simplified Version • “Canon in D” (Pachelbel)
    I published an article on 11 November 2023 called Wedding March For The Lazy Organist, which rather offhandedly made reference to a simplified version I created in 2007 for Pachelbel’s Canon. I often use it as a PROCESSIONAL for weddings and quinceañeras. Many organists say they “hate” Pachelbel’s Canon. But I love it. I think it’s bright and beautiful. I created that ‘simplified version’ for musicians coming to grips with playing the pipe organ. It can be downloaded as a free PDF if you visit Andrea Leal’s article dated 15 August 2022: Manuals Only: Organ Interludes Based on Plainsong. Specifically, it is page 84 in that collection—generously offered as a free PDF download. Johann Pachelbel (d. 1706) was a renowned German organist, violinist, teacher, and composer of over 500 works. A friend of Bach’s family, he taught Johann Christoph Bach (Sebastian Bach’s eldest brother) and lived in his house. Those who read Pachelbel’s biography will notice his connection to two German cities adopted as famous hymn tune names: EISENACH and ERFURT.

    PDF Download • “Anima Christi”
    I received a request for an organ accompaniment I created way back in 2007 for the “Anima Christi” Gregorian Chant. You can download this PDF file which has the score in plainsong followed by a keyboard accompaniment. Many melodies have been paired with “Anima Christi” over the centuries, but this is—perhaps—the most common one.

Random Quote

“Unfortunately, on the one hand a deadly error in judgment placed the official leadership of this committee into the hands of a man who—though generous and brave—was not very knowledgeable: Cardinal Lercaro. He was utterly incapable of resisting the maneuvers of the mealy-mouthed scoundrel that the Neapolitan Vincentian, Bugnini, a man as bereft of culture as he was of basic honesty, soon revealed himself to be.”

— ‘Fr. Louis Bouyer, an important member of the Consilium’
