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.”

Now Available! Organ Accompaniments for Latin Mass Hymnal

Cynthia Ostrowski · February 25, 2013

AST WEEK, 800 pages of organ accompaniments for the Campion Missal & Hymnal [url] began shipping. Before long, the SATB scores will also become available. Using these large, easy-to-read organist scores, parish musicians can provide accompaniment for all the music found in the Campion book (Ordinarium Missae, Hymns in English & Latin, Simple Gregorian Chants). Here is the URL address to purchase these accompaniments:

     *  Organ Accompaniments • for the
         St. Edmund Campion Missal & Hymnal

Here’s an abbreviated description of each volume:

ORGANIST VOLUME I  •  388 pages long, spiral bound.
This book contains three (3) different harmonizations of the the Gregorian Kyriale:
          1.) Achille P. Bragers, LOW KEY;
          2.) Carlo Rossini, MIDDLE KEY;
          3.) Flor Peeters et al., HIGH KEY.

ORGANIST VOLUME II  •  374 pages long, spiral bound.
This book contains four (4) sections. The chant accompaniments were done by Henri Potiron, Julius Bas, and others. Information given on the Vaticana chant rhythm also applies to Volume I.
          1.) Organ accompaniments for all hymns in the Campion Hymnal;
          2.) Transpositions & alternate harmonizations for many hymns;
          3.) Information on interpreting the Editio Vaticana rhythm;
          4.) Organ accompaniments for the “Simple Chants” in the Campion Hymnal.

The Nova Organi Harmonia accompaniments were created during World War II by faculty members of the Lemmens Institute (Belgium): namely, Flor Peeters, Msgr. Jules Van Nuffel, Msgr. Jules Vyverman, Marinus de Jong, Gustaaf Nees, Henri Durieux, and Edgard de Laet.  Achille P. Bragers, born in Belgium but famous in America, also studied at the Lemmens Institute, as you can see in Bragers’ biography (PDF article).  Carlo Rossini, famous for his “Psalm Tones,” was a priest musician who worked in Philadelphia (and, later, Rome).

    Simplified Accomp. • Schubert’s “Ave Maria.”
    Sometimes the organist must simultaneously serve as the CANTOR. (Those who work in the field of church music know exactly what I’m talking about.) One of our contributors composed this simplified keyboard accompaniment for Franz Schubert’s “Ave Maria,” a piece which is frequently requested for Catholic funerals and weddings. In terms of the discussion about whether that piece is too theatrical (‘operatic’) for use in Church, I will leave that discussion to others. All I know is, many church musicians out there will appreciate this simplified version.

    “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.

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

“Even after 1600 A.D.—despite major changes in musical taste—the compositions of Father Cristóbal de Morales were reprinted at Venice. Indeed, and as late as 1619 A.D. one Venetian publisher found his magnificats still in sufficient demand to make a profitable commercial venture out of issuing a new transcribed version for equal voices.”

— Dr. Robert Murrell Stevenson (d. 2012)
