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 • “Extremely Rare” — German Organ Accompaniment for Hymnal (158 pages)

Jeff Ostrowski · April 26, 2025

BEGAN WORKING for Corpus Christi Watershed as an employee for $7.50 per hour. Eventually, I was elected president by the board of directors. Like all officers, I serve at the pleasure of the board. (I’m not a board member.) One predominant “mission” or “objective” of mine is to make sure the entire website always remains free, without even requiring a login. Over the years, we have amassed something like 26 million downloads. If we required paid membership, I believe our influence and reach would be severely curtailed.

This Year • This year, we tried an experiment. Sending out letters of acknowledgment to our monthly donors, we included a PDF link to an extremely rare organ accompaniment for a German hymnal (158 pages). The idea was to “reward” our donors by giving them a special gift.

The Future • I realize other websites provide “exclusive content” to those who pay a membership fee. As I’ve already explained, I have always rejected this idea. I feel it’s crucial to offer everything for free. Am I foolish for believing this? It’s certainly possible. Perhaps someday we will offer “premium content”—but I think it would be annoying for folks to have to keep entering a login (especially if they’re trying to access our website from a different device).

Get Your Download • If anyone reading this is willing to sign up as a monthly donor, please contact us via email so we can send you the ‘secret’ link to the PDF file. (Again, the only people who currently have access to it are those who donated in 2024.) The hymnal contains many interesting organ interludes:

*  PDF Download • Organ Prelude

The hymnal contains numerous “Singmesse” specimens:

*  PDF Download • Lateinische Singmesse

Many hymns from the Brébeuf Catholic Hymnal also appear in this rare hymnal. For example, #736 in the Brébeuf matches this one:

*  PDF Download • O Esca Viatorum

Many people know “Omni Die, Dic Mariae” (Daily, daily, sing to Mary), and the German hymnal provides a groovy little introduction:

*  PDF Download • Omni Die, Dic Mariae

“Christus Ist Erstanden” is a favorite hymn of singers, as well as composers such as Sebastian Bach, Heinrich Schütz, and Max Reger :

*  PDF Download • Christus Ist Erstanden

Conclusion • If you value what we offer on our website, please consider donating $5.00 per month, or even $3.00 per month. We’re a tiny 501(c)3 public charity which exists solely by the generosity of small donors. We have no endowment; we have no major donors; we run no advertisements; we have no savings. Please alert others to what we’re trying to accomplish. Thank you!

    “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

“If the right is given to African tribes to include their pagan traditions in the liturgy, I think the same should also be given to the rite of a thousand year-old Christian Church, based on a much older Roman tradition.”

— Professor László Dobszay
