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 • “Gloria In Excelsis” With 3-Voice Polyphony By Cristóbal De Morales

Jeff Ostrowski · June 24, 2015

606 Mediaeval Manuscript IMAGE E HAVE recently been singing polyphony for three voices—whereas most choirs focus on SATB—and I’ve been extremely pleased with the results. Could this have something to do with how each vocal line sounds so “pure” in music written for three parts? Perhaps.

Here’s a lovely setting of the GLORIA which twice breaks into polyphony for three voices. A short excerpt demonstrates this:

Once your choir knows the piece, encourage them to read directly from the 15th-century notation—included in the following PDF—because this often heightens musicality:

For years, Gloria II struck me “dark,” but eventually it became one of my favorites.

    Heretical Hymns
    As a public service, perhaps a theologian ought to begin assembling a heretical hymns collection. A liturgical book—for funerals!—published by the Collegeville Press contains this monstrosity by someone named “Delores Dufner.” I can’t tell what the lyrics are trying to convey—can you? I detest ‘hymns’ with lines such the one she came up with: “Let the thirsty come and drink, Share My wine and bread.” Somehow, the publication was granted an IMPRIMATUR by Most Rev’d Jerome Hanus (bishop of Saint Cloud) on 16 August 1989. It’s a nice tune, but paired with a nasty text!

    Our tiny 501(c)3 nonprofit organization exists solely by generous readers who donate $5.00 per month. We have no endowment; we have no major donors; we run no advertisements; we have no savings. A donor wrote to us: “I so appreciate all you do and have done, and your generosity is unprecedented. I am honored to be able to make a monthly contribution.” Another monthly donor says: “Thank you for everything CC Watershed does. We are able to add so much solemnity to Holy Mass due to the resources made available here.” Can you spare a few dollars each month to help us survive?

    Dom Pothier • Photo from 1904
    Dom Paul Cagin, in a 1904 publication (L’oeuvre de Solesmes dans la restauration du chant grégorien) made sure to include a beautiful image of Dom Pothier, the legendary abbot of St-Wandrille. Also shown is a very young Dom André Mocquereau. Auguste Pécoul—considered the spiritual “son” of Abbat Prosper Guéranger of Solesmes—wrote as follows on 24 June 1901: “To forestall any confusion, let us remember that there is just one Gregorian notation—that restored, according to the ancient manuscripts, by the eminent Abbot of Saint-Wandrille, Dom Pothier.” ✠

    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.”

    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.
