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.”

2 January 2021 • Temptation

When I see idiotic statements made on the internet, I go nuts. When I see heretics promoted by people who should know better, I get angry. Learning to ignore such items is difficult—very difficult. I try to remember the words of Fr. Valentine Young: “Do what God places in front of you each day.” When […]

“Homily — Feast of Mary, the Mother of God, Years ABC” • Father Valentine Young, OFM

We seem to be sitting around waiting for “that day” when everything in the world, in our country, and in the Church is going to be perfect…

31 December 2020 • “COMITES CHRISTI”

The feasts for Saint Stephen Proto-Martyr (26 December), Saint John the Evangelist The Disciple Whom Jesus Loved (27 December), and the Feast of the Holy Innocents (28 December) seem untouched by any liturgical reforms. These are very powerful feasts—I believe they once possessed octaves—and I believe they could sometimes “overpower” a Sunday feast. The rules […]

“Homily — Feast of the Holy Family, Year B” • Father Valentine Young, OFM

I can speak mainly from my experience with Indians, more specifically the Navajos; their native culture has a great respect and love for marriage and family life.

To show our singers how special our music is, I’ve included ancient MSS for each piece—as well as rehearsal videos.

23 December 2020 • A 5th? or 4th?

I have noticed that where the Editio Vaticana has a descending perfect fourth for the Gradual of Christmas Midnight Mass, many ancient manuscripts have a descending perfect fifth, which is pretty cool: Example A — Example B. The Vatican Edition is a CENTO, and never made any claim to be anything other than a CENTO. […]

“Blessing the Bell” • Most Rev’d Alejandro D. Aclan

When a monk hears the bell, he stops whatever he’s doing and immediately goes to prayer. It is the voice of God calling us to pray, to avoid sin, and to forget the things of this world and think of Him.

“Rorate Mass” (FSSP) • 12 December 2020

Attendance was standing room only. Afterwards, the children presented roses to Mary—as the entire parish prayed the Rosary—and then we consecrated California to Jesus Christ.

“Homily — 3rd Sunday of Advent, Year B” • Father Valentine Young, OFM

As the Gloria during Mass suggests, we should “thank Him simply because of His great glory.” When is the last time you did that?

“Martinelli’s Letter” (dated 18 February 1910)

My recent post on the repercussion has induced some to ask: “Can we just sing whatever rhythm we want for the Vatican Edition? What about mensuralism? What about Bonvin and Vollaerts?” For those of us who work in the Extraordinary Form, we must follow the rhythm of the Editio Vaticana, and this was addressed in […]

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.

    “Reminder” — Month of Febr. (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.

    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.

Random Quote

There is a lack of that kind of organization which favors mature judgment. Move on, move on, get it out. Schemata are multiplied without ever arriving at a considered form. The system of discussion is bad … Often the schemata arrive just before the discussions. Sometimes, and in important matters, such as the new anaphoras, the schema was distributed the evening before the discussion was to take place … Father Bugnini has only one interest: press ahead and finish.

— Cardinal Antonelli (Peritus during the Second Vatican Council)
