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.”

6 November 2020 • FEEDBACK

The director of music at EWTN wrote to us about the Brébeuf hymnal: “I do believe your hymnal has the best harmonizations available. We have used several of your harmonizations on EWTN. I have recommended to other hymnal editors that they get aligned with Corpus Christi Watershed to improve their harmonizations. Take care.”

Msgr. Schmitt backs up Rev. Fortescue

My colleague, Andrea Leal, recently posted something extraordinary: an English translation of a NOTITIAE document from 1970 which explains why the reformers did such violence to the ancient Proprium Missæ. The author of that document erroneously claims that Gregorian composers changed the wording for musical purposes, but the real reason Missal and Gradual don’t always […]

“Polyphonic Credo” during Communion?

It sounds strange to Americans, but a very common European tradition is to sing a polyphonic “Agnus Dei” during the distribution of Holy Communion, famously defended by Cardinal Ratzinger in 1995. Monsignor Francis P. Schmitt wrote about visiting Saint Joseph Oratory in Montreal, and says: “A polyphonic Creed was sung during the distribution of Communion.” […]

The Best We’ve Done?

Perhaps the most significant item we’ve yet had the honor of producing is an English translation of an extremely rare document from 1970. A member of the Consilium—Father Adalbert Franquesa Garrós—explains why the reformers felt it necessary to destroy most of the ancient Mass propers. In particular, this reformer priest claims that unless verses of […]

President’s Corner

    “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

“We must say it plainly: the Roman rite as we knew it exists no more. It has gone. Some walls of the structure have fallen, others have been altered—we can look at it as a ruin or as the partial foundation of a new building. Think back, if you remember it, to the Latin sung High Mass with Gregorian chant. Compare it with the modern post-Vatican II Mass. It is not only the words, but also the tunes and even certain actions that are different. In fact it is a different liturgy of the Mass.”

— Fr. Joseph Gelineau (1978)
