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.”

When to Teach Children to Sight-Read Plainsong

Children can and should be taught Gregorian chant by hearing and repeating—but this binds them to singing only what they have memorized.

Dr. Lucas Tappan · January 3, 2017

God or Nothing

I think we can slay the current and popular belief that by making the liturgy, and by extension liturgical music, “relevant” to people we will somehow bring them back to God.

Keep the flame of the true Christmas spirit burning brightly and carol to your heart’s content.

Appropriate Music for the Sacred Liturgy

It’s hard to implement a program of truly sacred music, focused on the Lord, when so many of our Masses and other services are celebrated as if God were a side note…

A Late Gift for Nicholasmas

Unfortunately we live in a society in which parents can no longer allow the culture to help form their children, and in most instances are forced to fight such an un-cultural leviathan.

Where Does Your Heart Lie?

If Christmas day arrives and you haven’t been to confession, your daily prayer has suffered, and you haven’t eaten supper with your family at least five nights a week during Advent, you’re in too far.

Music for the Year of Mercy

Puccini’s music allows us to glimpse the love of a Father, Who doesn’t merely sit on the 50 yard line waiting to see which side of the eternal line we die on…

President’s Corner

    💲 5.00 💵
    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 • “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.

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

“It is the choir that can make the most valuable contribution to the liturgy; it is through the choir that significant numbers of the congregation can make a significant and valuable offering in the community’s act of worship. The choir links directly academic excellence, artistic creation, disciplined attention and self expression in the making of something fitting for the worship of God.”

— Father Daniel Higgins, Choirmaster at Saint Edmund’s College, Ware
