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.”

“Glory To God” • (For Choir + Congregation)

I wish to thank everyone for the nice comments I received vis-à-vis my Glory To God setting for Choir & Congregation. A gentleman with a musical doctorate from Indiana University wrote: “Love this setting so much. And I will pray, as you asked, for your return to composition more fully. You are very very good.” […]

William Byrd • “Mass for Five Voices”

Our volunteer choir is learning the “Sanctus” from William Byrd’s Mass for Five Voices. You can hear a short excerpt (recorded last Sunday) but please ignore the sound of babies crying: Mp3 recording. We still have work to do—but we’re on the right track. Once we have some of the tuning issues fixed, I desire […]

“Baptism” • A Unique Hymn

Father Christopher Phillips is the founding Pastor of Our Lady of the Atonement Catholic Church. One of his hymns is unique and (in my humble opinion) quite beautiful. His hymn is basically a prayer to the Holy Trinity but also speaks of Baptism and the Holy Eucharist. It would be an ideal Communion hymn on […]

For the Record: “Jeff Plays Organ”

Twenty-five years ago, if you’d told me I would end up as an organist, I would have laughed. But God seems to have had a different plan! I intend to record every hymn in the Brébeuf Hymnal on the pipe organ (if our Savior gives me the time and energy). You can hear my first recording […]

    “Reminder” — Month of April (2026)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. It couldn’t be easier to subscribe! Just scroll to the bottom of any blog article and enter your email address.

    Simplified Accompaniment (Easter Hymn)
    Number 36 in the Brébeuf Hymnal is “At the Lamb’s high feast we sing,” an English translation for Ad Cenam Agni Próvidi (which was called “Ad Régias Agni Dapes” starting 1631). As of this morning, you can download a simplified keyboard accompaniment for it. Simply click here and scroll to the bottom. Many organists are forced to serve simultaneously as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult—which explains why choirmasters appreciate these simplified keyboard accompaniments. Sadly, many readers will click that link but forget to scroll to the bottom where the simplified PDF file is located.

    PDF Download • “Quasi Modo Sunday”
    The Introit for “Quasi Modo Sunday” (12 April 2026) is particularly beautiful. The musical score can be downloaded as a PDF file, and so can the organ accompaniment. The official language of the Catholic Church is Latin (whereas Greek is our mother tongue). Vatican II said Gregorian Chant must be given “first place” under normal circumstances. As a result, some parishes will rightly sing the authentic version. On the other hand, because so many USA dioceses disobey the mandate of Vatican II, some musicians sing plainsong in the vernacular. I have attempted to simultaneously accompany myself on the pipe organ while singing the English version. Although very few take advantage of it, the complete Proprium Missae is posted at the flourishing feasts website.

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

“I am now old but I was young when I was received into the Church. I was not at all attracted by the splendour of her great ceremonies—which the Protestants could well counterfeit. Of the extraneous attractions of the Church which most drew me was the spectacle of the priest and his server at Low Mass, stumping up to the altar without a glance to discover how many or how few he had in his congregation; a craftsman and his apprentice; a man with a job which he alone was qualified to do.”

— Evelyn Waugh (7 August 1964)
