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.”

“Spoken vs. Sung Propers” • The Complete History

Lies containing a little truth are the most difficult to quash • Here is the definitive, final exposé on why the “Spoken Propers” don’t match the “Sung Propers.” • In October of 1972, the Bishops’ Committee on the Liturgy falsely equated the “Spoken Propers” with the “Sung Propers” and proclaimed: “These antiphons are too abrupt for communal recitation” • Several official English translations of the Roman Gradual have received the imprimatur multiple times+

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 […]

“A blast from the past”

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.”

    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.
