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.”

Three Radical Liturgical Changes • (Pope Pius XII)

I love Venerable Pius XII very much, but this particular change was unconscionable.

Singers • High or Low?

I consider myself a “flexible” choirmaster. When I sing with men who have low voices, I join with them at a low pitch. Here’s an excerpt from yesterday, which was LAETARE SUNDAY (the 4th Sunday of Lent). Later that same day, I sang at another Mass with a singer who has a very high voice. […]

15 March 2021 • Lætare Compliment!

I agree with Keven Smith that Covid-19 has been a huge boon to my skills of improvisation on the organ. I wanted to share this amazing email (which gave me such joy), sent to me by somebody I don’t know: “My name is —— and I attended the 7:00pm Mass today at St Vitus. The […]

11 March 2021 • From Last Sunday…

Like everyone else, we are struggling under the Covid-19 restrictions. The number of singers we’re allowed have has been reduced in a severe way. But we charge forward, trusting in God. Here is a 50-second live excerpt from Mass last Sunday here in Los Angeles. Not many voices, but still beautiful (in my humble opinion).

4 March 2021 • Can you spare 15 seconds?

Due to Covid-19, California has basically been under “lock down” for 11 months, and these restrictions have had quite a detrimental effect on choral programs. We are frequently limited to just 2-3 singers, on account of regulations by the government and our Archdiocese. However, although the number of singers is quite small, I was struck […]

    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

We cannot exaggerate our indebtedness to Dr. Julian’s “Dictionary of Hymnology,” a monumental work, without which we could not have reached the high standard of accuracy, as to both texts and authorship, which we set before us when entering upon our labours.
