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.”

Msgr. Richard Schuler and the Piccoluomini

Sure enough, a few hours after the phone call, I happened to be searching the internet and I came upon the biography of Pope Pius II. What was his name before becoming pope? You guessed it !!!

Catholic News Agency Praises Vatican II Hymnal

“The paper is of the highest quality with a resilient binding, the designs, beautifully appointed. It has the readings for all Sundays and feast days – the complete cycles, A, B, C. It will be about twenty years or perhaps thirty before another translation is made. Here is music for the new evangelization. The Vatican II Hymnal serves as a musical ambassador for Christ.” —Sr. Joan L. Roccasalvo

Mourning Pope Benedict XVI and Trusting the Holy Spirit

The Church’s vast treasury of sacred music belongs to the people! This is the truth that will bear out.

Dr. Theodore Marier And Pope Francis

Our new Holy Father, Pope Francis, seems to be less interested in the Liturgy than his immediate predecessor. Some are asking, “What will become of the Liturgical movement called for by Pope Benedict and popes before him?”

Communion in the Hand

The permission to receive Holy Communion in the hand is a dangerous aberration that must be rescinded if the Church is to achieve spiritual health again.

    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

“I vividly remember going to church with him in Bournemouth. He was a devout Roman Catholic and it was soon after the Church had changed the liturgy (from Latin to English). My grandfather obviously didn’t agree with this and made all the responses very loudly in Latin while the rest of the congregation answered in English. I found the whole experience quite excruciating, but my grandfather was oblivious. He simply had to do what he believed to be right.”

— Simon Tolkien (2003)
