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.”

Jeff Ostrowski · January 25, 2023

HE TRUTH IS STRANGER than fiction. For example, it’s fascinating how JACKIE GLEASON couldn’t read a note of music, yet produced 100+ albums and still holds the record for the longest stay on the Billboard Top Ten Charts. Gleason’s first ten albums sold over a million copies each! Something else I find endlessly fascinating is how plainsong’s Melismatic Mora Vocis (which I have referenced so often) was completely forgotten for a century, due to the popularity of the rhythmic modifications Dom Mocquereau imposed on the official edition. It’s as if nobody was curious about the thousands of elongations added by Dom Mocquereau. Indeed, after one realizes what Dom Mocquereau did, it becomes impossible to “unsee” the bizarre way his additions were squeezed in, since the Vatican made it clear to Dom Mocquereau—by means of a letter dated 6 September 1906—that he wasn’t allowed to change any of the blank spaces.

No Condemnation • In spite of what some have claimed, I do not “condemn” those who follow the Mocquereau rhythm (as I did for more than 20 years). At the same time, we should understand what took place. In my opinion, we have no obligation to “conceal” or “suppress” the truth. For this reason, I have attempted to let people know why some choose to sing the Editio Vaticana the way it was intended to be sung by those who—at the behest of Pope Saint Pius X—created it.

Perfect Conformity • The 1909 SCHWANN EDITION is one of the most faithful books when it comes to the official rhythm. I’m tempted to say it is more faithful than any other book, but Father Mathias is also quite faithful, and so is the LEMMENSINSTITUUT faculty. Corpus Christi Watershed has paid to have this incredibly rare book professionally scanned:

42970-Schwann-Modern-Notation-Epitome-E-Graduali-001

The technical title is Epitome E Graduali, because it’s not “complete” inasmuch as certain items (such as Graduals and Tracts) have been simplified. This book is also known as Römisches Gradualbuch. I can’t imagine how many hours of painstaking work were required to produce such a book.

Can You Help Us?

We Desperately Need Donations! • I believe so strongly in what we are doing, I’m not ashamed to beg. Obtaining these rare books (and having them professionally scanned) has required thousands of dollars. We have more books to release, but more are waiting to be scanned. When we scan them “in house” the quality suffers—although the file size is much larger (which is inconvenient for our readers). That’s why we prefer to have these books scanned professionally. The online library our organization has created is about 24x larger than the UCLA music library (in terms of liturgical books) … and you can access all the books completely free of charge!

Can you please make a donation right now?

    PDF • “3-Voice Motet” (Father De Laet)
    I believe 99% of our readers will recognize this hymn tune. Perhaps Father Edgard De Laet should have called it a ‘hymn’ instead of a ‘motet for three voices’—but he’s technically correct, since MOTET is defined as: “a short piece of sacred choral music, typically polyphonic and unaccompanied.” The even verses are for three voices, as you will see if you download the PDF score at #20245. The odd verses may be song a cappella SATB or unison with organ.

    PDF Download • “Hymn for 2 Voices”
    Readers who click on this video will see that it starts with verses of the “Pange Lingua” hymn by Saint Thomas Aquinas (d. 1274) arranged for two voices. However, there’s a polyphonic refrain (“Tantum Ergo”) for three voices, taken from Kevin Allen’s Motecta Trium Vocum. If your choir is very small, this piece is for you! You can download the PDF score free of charge—and you can also utilize the rehearsal videos for each individual voice—by navigating yourself to #20323.

    “Holy Name Hymn” (2-Voice Arrangement)
    When we post a direct URL link, we frequently get thousands of downloads. But when scrolling is required, very few take the time. I mention this because those who click on this URL link and scroll to the bottom can download—completely free of charge—a clever 2-voice arrangement for a famous hymn to the Most Holy Name of Jesus. In a pinch, it can be nicely sung by one male and one female! It will be of interest to those who seek arrangements for two voices.

Quick Thoughts

    PDF Chart • “Plainsong Rhythm”
    I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”

    “Reminder” — Month of January (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. Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.

Random Quote

Ralph Vaughan Williams “was an atheist during his later years at Charterhouse and at Cambridge, though he later drifted into a cheerful agnosticism: he was never a professing Christian.”
