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.”

Important Resources for Liturgical Reform (6 of 7)

Andrew R. Motyka · August 13, 2014

ET’S SEE: CanticaNOVA, CPDL, the nearly-infinite number of resources offered here on CCW. All these have already been presented by my esteemed colleagues. I liked this “series” idea better when I could go first and take all the good ideas.

In seriousness, though, here are some good resources for the primary tools we each have at our disposal: cantor, choir, and organ.

An often overlooked resource for the parish choir is the Graduale Simplex. This book, which originally was published in 1967, has much simpler settings of chant propers than the Graduale Romanum. One challenge is that, since the first edition was released before we even had a revised order of Mass, it can be difficult to line up and use liturgically. Thankfully, we have several derivative works that make it more accessible in the average parish. First is Paul Ford’s By Flowing Waters. It is a relatively straightforward English adaptation of the chants found in the Simplex, with some accommodations to the tunes to more easily accept the English text. A second, more unknown resource is Aristotle Esguerra’s Choral Simplex, another English language setting, but in SATB harmony. Esguerra’s treatment of the melodies and adaptations for choir shows an elegance and a clear mind for choral singing. I strongly recommend it.

Since most parishes only have one “choir Mass” per weekend, resources for cantors can be helpful, too. I would be far too selfless if I didn’t mention these Communion Antiphons, and selflessness is something I can only aspire to. They are antiphons settings that are free, simple, free, congregational, accompanied, modal, complete, and free.

Lastly, I would like to call to attention a not-specifically-Catholic resource, but one I think needs to be known nonetheless. Just like CPDL (the Choral Public Domain Library) offers thousands of free choral scores online, IMSLP (the International Music Score Literacy Project) offers free choral AND instrumental scores. This is a great resource if you are an organ hack like me who needs to broaden your organ-literature horizons greatly. There are thousands of free scores, searchable by many criteria, including instrumentation, genre, solo type, etc. Care needs to be taken about whether or not each score is actually in the public domain in your country, however. Since IMSLP is based in Canada, where everything falls into the public domain in 50 years, there are some scores that are free on that website that are illegal to download in the US. Watch your dates and you’ll be fine. This is a pretty minor drawback considering the volume of usable scores on the site.

We directors are always on the lookout for free resources for our choirs and music programs in general. Hopefully you can find some use for these, as well as the others in this series.

    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

Participation at Mass must be “above all internal” (§15), and: “The faithful must be taught to unite themselves interiorly to what the ministers or choir sing, so that by listening to them they may raise their minds to God.”

— Musicam Sacram (5 March 1967)
