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.”

Does Watershed Make A Difference?

Jeff Ostrowski · September 13, 2017

4450 picture S YOU KNOW, all of us here at Watershed are volunteers. We have no staff and no salaries. Every so often, my fellow bloggers and I wonder if we are making an impact on the “real world.”

Here’s something powerful we recently received from Maryland:

Dear Corpus Christi Watershed,

I wanted to send a note to tell you what an incredible blessing your webpage and blog have been to me.

I am a vocalist and have been all my life. I am very studied, though I have no formal degree in music (in high school, thinking I’d never pay the bills with music, I got a degree in something else that makes no money and required a Master’s degree for employment!). I am an educator by trade. When I had my first child, I quit working full time but was asked shortly after to cantor at my parish—I wasn’t even fully Catholic at the time! Through much prayer, I discerned God was calling me to lead my parish’s music program when our brand new pastor came to our parish in 2013. I was hired as a part-time music director in early 2014 (right before finishing RCIA and being received into the Church at Easter Vigil).

For the past 3.5 years, I have been systematically implementing much of the good advice and practice I’ve gleaned from reading Views from the Choir Loft and endlessly exploring the Watershed website. Formerly our parish had folk Masses, Breaking Bread Missals, a volunteer choir that didn’t formally practice, and cantors only at big events. Now we have mostly organ-led Masses every weekend and feast, a more traditional Missal and Hymnal—allowing us to implement the communion antiphon—a regularly meeting and practicing choir, and (last year) we regularly sang in 2-part harmonies!

This past spring, you re-posted the Polyphonic rehearsal videos on Facebook and I knew I had to take advantage of that golden resource. Our county’s deanery planned a Fatima pilgrimage: a celebration the 13th of the month for six straight months at a different parish around the county. I knew when I saw those rehearsal videos that we had to utilize them for our turn (which was tonight).

I have an all-female choir of about 8 dedicated women who sing every Sunday. During Christmas and Easter I convene a “festival choir” and get a few more volunteers to make our bigger Masses more special. So, I recruited another 15 men and women to join us for tonight’s Mass, using music almost entirely from your page:

—Guerrero’s Missa Iste Sanctus

—Hymn to Mary

—Hail, Holy Queen

—A communion antiphon for the Marian Mass we chose that Richard Rice whipped up for me when I cried for help on the CMAA page a few days ago!

—Filled out the time with a few well known Marian and Eucharistic hymns.

We had about 250-300 in attendance (full for our little parish). It was a huge success! My pastor was blown away at the beauty of the Mass setting by Guerrero. The people in attendance were just floored by how the 4-part choir enhanced the Mass. To quote our priest and echoed by others, they felt “like we were in heaven.” One older gentleman and his wife approached me after Mass and thanked me for the pleasant surprise. He said “I already knew I was going to witness the miracle of the Blessed Sacrament tonight, but never did I think I’d open a program and see the MISSA ISTE SANCTUS.”

I just cannot thank you enough for how much your ministry has helped me grow and helped me introduce my parish to the incredible sounds that the human voice is capable of. I hope you’ll share some of my story on your blog and social media to encourage others to get out of their comfort zone and try beautiful things in their liturgies! My only regret is that with the stress of the night, I didn’t get any video or audio to send to Jeff Ostrowski so he could he could hear how all his soprano singing was worth it—to see little old ladies and scared young tenors singing sacred polyphony for the first time in their lives!


For whatever reason, these last two weeks have been full of heavy crosses.

A letter like this was so gratifying to receive!

    2-Voice Arrangement for Lent
    Those seeking a two-voice arrangement for LENT and PASSIONTIDE should click here and scroll down. It’s based on number 775 in the Brébeuf Hymnal, with an enchanting melody written by Kevin Allen (the legendary American composer of sacred music). That text—“Pendens In Crucis Cornibus”—is often used for the Feast of our Lady of Sorrows. That link is important because, in addition to the musical score, it provides free rehearsal videos for each individual voice: something volunteer choirs appreciate!

    “Sanctus VIII” • Organ Accompaniment
    A few days ago, I composed this organ harmonization for SANCTUS VIII. This Mass is traditionally called Missa de ángelis or “Mass of the angels.” In French, it is Messe de Anges. You can evaluate my attempt to simultaneously accompany myself on the pipe organ (click here) while singing the melody. My parish is currently singing this setting.

    Music List • (5th Sund. Ordinary Time)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for this coming Sunday, 8 February 2026, which is the 5th Sunday in Ordinary Time (Year A). If such a thing interests you, feel free to download it as a PDF file. You will probably notice it isn’t as ‘complete’ or ‘spiffy’ as usual, owing to some difficulties which took place this week.

    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!

    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

“The Pope is not an absolute monarch whose thoughts and desires are law. On the contrary: the Pope’s ministry is a guarantee of obedience to Christ and to his Word. He must not proclaim his own ideas, but rather constantly bind himself and the Church to obedience to God’s Word, in the face of every attempt to adapt it or water it down, and every form of opportunism.”

— ‘His Holiness, Pope Benedict XVI (11 May 2005)’
