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.”

Views from the Choir Loft

A Message From Mr. Roderick Royce!

Corpus Christi Watershed · January 21, 2024

R. RODERICK ROYCE graduated from BOISE STATE UNIVERSITY (Idaho) with a bachelor’s degree in music education. He has sung in multiple choirs through the years, including the Cathedral of Saint John the Evangelist (Roman Catholic) under Dr. Ray Morvant. He has taught orchestra for about thirteen years. Mr. Royce recently sent the following message vis-à-vis Jeff Ostrowski’s seminar: “Secrets of the Conscientious Choirmaster”.

Jeff Ostrowski is a choirmaster based in Los Angeles, California. He and a group of individuals have created the Corpus Christi Watershed website to supply musicians with musical resources for Catholic choirs. Ostrowski’s latest resource is a seminar: Secrets of the Conscientious Choirmaster. The seminar is focused on choral music (motets, hymns, Mass settings, and so forth) useful to those who provide music at the Extraordinary Form (“Latin Mass”) or at the Ordinary Form (“Novus Ordo Missae”). Ostrowski introduces techniques and tools to help choirmasters improve as musicians and fall in love with the art of learning choral music all over again. Various items are treated: singing liturgical pieces of Catholic Music in Latin (including polyphonic pieces); Gregorian Chant, which is written in different modes; video recordings; and printable sheet music. Ostrowski teaches the choirmaster to better direct anybody—from an ‘average’ parishioner to the veteran choir member—how to sing hymnody in SATB parts and contrapuntal lines in polyphonic masterworks. He explains how to ‘build up’ the individual to add to the strength of the choir. He also encourages choirs to pray before rehearsals to strengthen their Catholic faith. Ostrowski has a “just do it” mentality. He patiently shows how to ‘speak’ and use Solfège on the most inspiring and difficult polyphonic pieces. Specimens he examines would include fugues and masterworks using imitative polyphony by Palestrina, Victoria, Guerrero, Croft, Morley, Lassus, and Josquin. After watching his seminar, I am more prepared to spend rehearsal time wisely, communicate effectively, and apply the tools he has taught me to help improve choir members.

    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.

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

“Our Christian people regard with great joy everything that contributes to the splendor of the ceremonies. Jesus—who was poor in His private life—received ointment on His feet. See Thomas Aquinas (Prima Secundae, q. 102, art. 5, ad 10) and the holy Curé of Ars. The Church has always loved beautiful churches, and so forth. We must preserve our sacred patrimony and make sure sacred objects do not become secular possessions.”

— Abbot & Council Father denouncing “noble simplicity” during Vatican II
