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.”

World Youth Day with polyphony and chant!

Christopher Mueller · April 12, 2016

WYD_Sydney Pilgrims at the 2008 World Youth Day, held in Sydney, Australia ANY of you know that World Youth Day is an event convened every 2-3 years, where high school and college-aged kids and young adults from all over the world gather in some large international city for a week, to celebrate Mass, meet the Pope (or at least be near him), and grow in their faith. This event is huge – millions of young people convene every time it happens! In fact, World Youth Day 1995 in Manila held the record for the largest-ever papal event, when over five million pilgrims gathered for Mass with Pope St. John Paul II. (That record was recently broken when Pope Francis celebrated a Mass for over six million people… in Manila!)

This summer World Youth Day will be held in Krakow, Poland, and I have the honor of having been invited to conduct all the music at the English-language Masses! There are so many English-speaking pilgrims that these Masses will be held in a giant stadium. There will be a morning Mass each day, for five consecutive days.

Additionally, my family, which sings polyphony and chant together as the Mueller Family Schola, has been invited to give a concert as one of the cultural events that take place each evening at this enormous gathering. And my wife and kids will not only be present for our concert, but they’ll be joining me to sing at all the Masses I’ll be conducting as well.

One of my goals is to incorporate polyphony and chant into every Mass. I think it would be amazing to set a kind of liturgical template that youth from all over the world would take back to their parishes. “We heard all this beautiful music at the Masses in Poland – can’t we have that same music at our own church?” I’ve been working closely with Dominican Friars from the United States and Poland as we carefully plan all these liturgies. And we expect a pretty big choir!

But here’s where I need your help:

In order to direct the wonderful music this July in Krakow, my family and I first have to get to Krakow. And so I’m asking if you would support our Kickstarter campaign, to help us raise enough funds to bring gorgeous polyphony, beautiful chant, and ourselves to Poland. We would be very grateful for your help, and we promise to pray for you unceasingly in our gratitude!

Thank you for your kind consideration and for your support —

Chris Mueller and the Mueller Family Schola

    Music List • (1st Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I’ve prepared for this coming Sunday—22 February 2026—the 1st Sunday of Lent (Year A). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the outstanding feasts website alongside the official texts in Latin. I spent an enormous amount of time preparing this ORDER OF MUSIC—because the children’s choir will join us—and some of its components came out great. For example, the COMMUNION ANTIPHON with Fauxbourdon is utterly resplendent, yet still ‘Lenten’.

    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.

    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

“Urban VIII appointed four Jesuits to reform the hymns, so that they should no longer offend Renaissance ears. These four, in that faithful obedience to the Holy See which is the glory of their Society, with a patient care that one cannot help admiring, set to work to destroy every hymn in the office.”

— Fr. Adrian Fortescue (1916)
