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.”

The modern armchair chant scribes

Veronica Brandt · February 14, 2015

Medieval writing desk N THE BEGINNING, PEOPLE LEARNT Gregorian chant by ear. Later it was transcribed into marks on vellum, painstakingly copied by hand. Then the printing press made paper copies which could be distributed far and wide. Now we have liquid crystal displays interpreting little packets of bits into images of sheet music and lasers fixing little particles of black to sheets of paper in the same images from the comfort of our own homes.

Medieval scribes used quill, ink and a scraper. Today a scattered group of musical technicians (or technical musicians) use GregoBase.

What is GregoBase?

GregoBase is a database of Gregorian Chant, arranged so that you (yes, you!) can log in and proof read the transcriptions and either make corrections or add corrections to the “Please fix” list for other gabc technicians to fix.

There are thousands of scores in the database already, with more being added. Books being transcribed range from the 1908 Vatican Graduale Romanum to the much more recent three volume Antiphonale Monasticum from Solesmes. The Liber Usualis is well covered.

Each score can be downloaded in several formats to suit every desktop publishing requirement. Most also come with a scan of the source page so proof reading can be accomplished even if you don’t have your own copy of the book.

Scores are indexed by first letter (or Incipit), by usage (Introit, Gradual, Varia, etc.) or by source book. There is also a tag system which will allow browsing by feasts and seasons.

Even my mother is using this. You can use this too! Enjoy GregoBase!

    Simplified Accomp. • Schubert’s “Ave Maria.”
    Sometimes the organist must serve simultaneously as the CANTOR. (Those who work in the field of church music know exactly what I’m talking about.) One of our contributors has created this simplified keyboard accompaniment for Franz Schubert’s “Ave Maria.” That piece is a frequent request for Catholic funerals. 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

They were not ashamed to lay their hands on Sedulius, on Prudentius, on St. Ambrose himself. Only in one or two cases does some sense of shame seem to have stopped their nefarious work. They left “Ave maris stella,” “Jam lucis orto sidere,” and St. Thomas Aquinas’s hymns alone (they would have made pretty work of “Sacris solemniis”). In 1629 their mangled remnants were published.

— Rev’d Adrian Knottesford Fortescue (25 March 1916)
