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.”

What you didn’t realize about World Youth Day…

Guest Author · October 28, 2016

704 Chris Y ALL ACCOUNTS, the music at this year’s World Youth Day was a great success. For example, Bishop James Conley, of Lincoln, Nebraska, wrote a wonderful piece about it, and Fr. David Friel, of Philadelphia contributed a lengthier analysis. Their conclusions were the same: Beautiful music helped thousands of young people to pray that holiest of prayers, the Mass. And for this, I’m very grateful.

When Fr. Jonathan Kalisch, O.P., a chaplain of the Knights of Columbus, proposed to me that I lead the music at the English-language site for World Youth Day 2016 in Kraków, Poland, I was thrilled. I am a proud Pole, born, raised, and educated in that wonderful country (and my formation as a priest took place largely in the Dominican priory in Kraków itself). I’m also somewhat of an itinerant American, having worked at parishes and campus ministries in New York City; Anchorage, Alaska; Seattle, Washington; and now Salt Lake City, Utah. Finally, I’m a church musician, trained as an organist, who also loves to sing and to collect suitable liturgical repertory from Poland and elsewhere. These were all contributing factors to my appointment: having been raised and formed in Poland, the liturgical music created there by the Dominicans brought me—quite literally!—to the Order, and this same music has become an essential part of my work in the United States. Having worked in America for many years, I’ve accumulated a large body of Polish and French repertory that has been translated into English, and I have a working sense of what student choirs and congregations can learn and sing. The charge that World Youth Day in Kraków somehow “sound like Poland” was my challenge to execute, and I was happy to take it on. For more about the “why” of the music, take a look at Fr. Friel’s piece, linked above, where he reproduces an essay I wrote for the World Youth Day Mass booklets.

WHAT I COULDN’T SAY THERE (because of space constraints) I’d like to say here: without the help of many wonderful collaborators, the music at World Youth Day’s Mercy Centre wouldn’t have happened. I’d like to take this opportunity to mention the many important people whose efforts brought that music to life.

While it’s been widely noted that the Dominicans—the religious order of which both Fr. Kalisch and I are members—were responsible for the music at the Mercy Centre, my most important collaborator wasn’t a Dominican at all! Christopher Mueller, a colleague and friend from my days back in New York City, was the person I tapped to conduct the ensemble in Kraków. But he did so much more than that: we were really partners, co-directors. Any accolades of mine must surely be shared with him, and here’s why:

(A) I selected about 60% of our repertory, and he the other 40%.

(B) He took upon himself the huge task of compiling all the music, which came from a variety of sources and required thorough editing.

(C) While a large part of my role was to handle organizational tasks (assembling the choir, setting up a rehearsal venue, and working with the Dominican Liturgical Institute — more on that later), Chris’s role was entirely a musical one. He led all the rehearsals and conducted at all the Masses. He planned out how our volunteer choir & orchestra was going to learn over 100 pages of music (around 30 different pieces) in a single retreat weekend, and he kept us focused and on-task during all our day-of rehearsals prior to the Masses.

(D) There were quite elaborate Mass booklets, which Chris designed and created by himself. He wanted the Mass booklets to be as beautiful and compelling as the Mass music, and he did not disappoint.

(E) After our four sung Masses at the Mercy Centre, we didn’t want to “waste” the fruit of our labors. In order to archive the musical material, Chris led a recording session in the beautiful medieval Church of St. Giles, and when he returned to the U.S., he did all the editing and post-production himself. Take a listen to the results here.

(F) Something else that Chris did when he got back to the U.S. was to annotate the web videos of our three big Masses, so that people could view/listen to specific pieces of music in context if they desired. Watch the Masses of Wednesday, Thursday, or Friday.

As I said, Christopher Mueller was my co-director, and we couldn’t have made it without his many talents and leadership!

ANOTHER KEY CONTRIBUTOR was the Dominican Liturgical Institute in Kraków, which for the past 30 years has led a major liturgical revival in Poland. Director emeritus Fr. Tomasz Grabowski, O.P., put together the very fine orchestra of young Polish musicians. Newly-appointed assistant director Fr. Grzegorz Doniec, O.P., prepared the full scores and instrumental parts as required, and was also the clarinetist in the orchestra. Additionally, the Institute recorded and released a CD of the music we would be presenting at WYD so that pilgrims could bring the music home with them as both keepsake and inspiration. 1

I’d also like to recognize Fr. Gabriel Torretta, O.P., an American Dominican, who helped in the musical planning, proofread the programs, and was my logistics assistant who helped keep things running smoothly in Kraków. As well as the three of us Dominicans, there were four Sisters of Life amongst the choir & orchestra, and we were very grateful for their presence, both musical and spiritual. And finally, all the singers and instrumentalists — they were the heart, soul, and sound of the ensemble. They volunteered to give a week and a-half of their time to fly to Poland and take part in this wonderful week of prayer and liturgy. Without them we would have had nothing!

I remain extremely grateful to every participant, and I think we showed that our “Polish” experience of liturgical beauty was really a universal experience for the Church. We hope that this approach to music will become more widespread, and I believe that through the labors of Christopher Mueller and all these fine musicians, it certainly will be.

    PDF Download • “Organ Accompaniment”
    Over the past few years, I’ve been harmonizing all the vernacular plainsong Introit settings by the CHAUMONOT COMPOSERS GROUP. This coming Sunday—10 May 2026—is the 6th Sunday of Easter (Year A). The following declaration will probably smack of “blowing my own horn.” However, I’d rank this accompaniment as my best yet. In this rehearsal video, I attempt to sing it while simultaneously accompanying myself on the pipe organ. The musical score [for singers] as well as my organ accompaniment can be downloaded free of charge from the flourishing feasts website.

    “Gregorian Chant Quiz” • 4 May 2026
    A few days ago, the CORPUS CHRISTI WATERSHED Facebook page posted this Gregorian Chant quiz regarding a rubric for the SEQUENCE for the feast of Corpus Christi: “Lauda Sion Salvatórem.” There is no audience more intelligent than ours—yet surprisingly nobody has been able to guess the rubric. Drop me an email with the right answer, and I’ll affirm your brilliance to everyone I encounter!

    “Rare Photographs” • Hannibal Bugnini
    On 2 September 2025, we included in this article extremely rare photographs of Archbishop Hannibal Bugnini taken in Iran circa 1979. Bugnini had initially been banished by the pope to Uruguay, but he refused to obey. [This is interesting, since Bugnini relied upon ‘blind obedience’ when it came to modifications of the ancient liturgy.] After he refused to obey the order from the pope, Hannibal Bugnini was banished to Iran. You can also watch a short video of Hannibal Bugnini in Iran, dated 10 November 1979. That’s about a week after the USA embassy hostage crisis began in Tehran, and Pope Saint John Paul II had sent the leader of the Iranian Revolution a special letter.

    Simplified Version • “Canon in D” (Pachelbel)
    I published an article on 11 November 2023 called Wedding March For The Lazy Organist, which rather offhandedly made reference to a simplified version I created in 2007 for Pachelbel’s Canon. I often use it as a PROCESSIONAL for weddings and quinceañeras. Many organists say they “hate” Pachelbel’s Canon. But I love it. I think it’s bright and beautiful. I created that ‘simplified version’ for musicians coming to grips with playing the pipe organ. It can be downloaded as a free PDF if you visit Andrea Leal’s article dated 15 August 2022: Manuals Only: Organ Interludes Based on Plainsong. Specifically, it is page 84 in that collection—generously offered as a free PDF download. Johann Pachelbel (d. 1706) was a renowned German organist, violinist, teacher, and composer of over 500 works. A friend of Bach’s family, he taught Johann Christoph Bach (Sebastian Bach’s eldest brother) and lived in his house. Those who read Pachelbel’s biography will notice his connection to two German cities adopted as famous hymn tune names: EISENACH and ERFURT.

    PDF Download • “Anima Christi”
    I received a request for an organ accompaniment I created way back in 2007 for the “Anima Christi” Gregorian Chant. You can download this PDF file which has the score in plainsong followed by a keyboard accompaniment. Many melodies have been paired with “Anima Christi” over the centuries, but this is—perhaps—the most common one.
