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.”

    PDF Download • Communion for Sunday
    The COMMUNION ANTIPHON with fauxbourdon psalm verses for this coming Sunday (3 May 2026) is elegant and poignant. It’s such a shame it only comes every three years. This piece—along with all the musical scores for this coming Sunday, which is the 5th Sunday of Easter (Year A)—can be downloaded free of charge from the flourishing feasts website. By the way, how is it already 2026?

    Season’s End Repertoire
    Looking at the REPERTOIRE SHEET until the end of the choral season, I see that I’ve fallen behind schedule. (The last three months have been extraordinarily busy.) As you know, I have been providing organ harmonies for all the ENTRANCE CHANTS—as well as rehearsal videos—and you can see I’m behind where I planned to be. Now I must make up lost ground. However, the choir picks up the ENTRANCE CHANT with ease, so I’m sure it will all work out. My ‘unofficial’ harmonizations are being posted each week at the flourishing feasts website.

    PDF Download • “Funeral Procession”
    From a mediæval Book of Hours, I was sent this glorious depiction of a Roman Catholic funeral procession by Simon Bening (d. 1561). The image resolution is extremely high. I’m not sure I know of a more beautiful illustration of a mediæval church. And I love how the servers are wearing red and pink cassocks!

Quick Thoughts

    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.

    PDF • “Liturgical Law” (467 Pages)
    On Good Friday during the middle ages, the pope privately recited THE ENTIRE PSALTER. If you don’t believe me, see for yourself by reading this passage by Dom Charles Augustine Bachofen (d. 1943). His famous book—called “Liturgical Law: A Handbook Of The Roman Liturgy”—was published by the Benjamin Herder Book Company, which was the American arm (operating out of St. Louis, Missouri) of one of the world’s most significant Catholic publishers. Dom Charles Augustine Bachofen was born in Switzerland but spent his career between the Benedictine monasteries at Conception (Missouri) and Mount Angel (Oregon). His 1931 masterpiece, Liturgical Law can be downloaded as a PDF file … 467 pages!

    “Gregorian Chant Quiz” • 24 March 2026
    How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!

Random Quote

“A father cannot introduce mistrust and division among his faithful children. He cannot humiliate some by setting them against others. He cannot ostracize some of his priests. The peace and unity that the Church claims to offer to the world must first be lived within the Church. ”

— Cardinal Sarah (14 August 2021)
