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.”

Biography • Christopher Mueller

Christopher Mueller · January 3, 2013

HRISTOPHER MUELLER is a church musician, conductor, and composer. His most well-known composition, the Missa pro editione tertia—a congregational setting of the 2011 ICEL translation of the Ordinary of the Mass—has been purchased by parishes in Australia, Canada, the UK, and throughout the USA. Most of his compositions are choral works written to be sung at Mass, including 40 Gregorian Introits (in Latin), a nearly-complete set of Responsorial Psalms for the 3-yr. cycle, 35 Offertory settings (in English), and numerous Masses, motets, sequences, and other works. He aims to write music befitting the liturgy out of gratitude to God, the Author of beauty. His two decades of work as a church musician—in the Ordinary Form of the Roman Rite—have focused on Renaissance polyphony and Gregorian chant (as well as his own compositions), first with a volunteer choir at the Church of Notre Dame in New York, NY, then with the professional SCHOLA POLYPHONICA at the Basilica of St. John the Evangelist in Stamford, CT; following that with the volunteer choir at the Church of St. Bernadette in Silver Spring, MD, and the professional schola he instituted at the National Shrine of St. John Paul II in Washington, D.C.  He is presently the organist and choirmaster at St. Louis Bertrand Church in Louisville, KY, where he serves with a wonderful cadre of Dominican Friars and directs a small professional schola.

1,400 Motets • His choirs rarely repeat music during the course of the choral year, singing 100 or more different motets each season, and he has created editions of at least 200 motets himself. Similarly, his choirs seldom repeated music from one year to the next (with notable exceptions), so that the always-changing musical experience of Mass was a reflection of the ever-new experience of Christ in the Eucharist. The texts of the motets are drawn from sacred Scripture: sometimes a setting of the day’s Offertory or Communion proper, sometimes a passage from the day’s readings, and occasionally an Office hymn or other related text. He estimates that his choirs have sung at least 1400 different Renaissance motets over the years. In addition to his musical work, he also spent seven and a-half years coordinating the marriage preparation program for the Archdiocese of New York, over the course of which he and his wife taught pre-Cana classes to thousands of engaged couples. He has an undergraduate degree in piano performance (classical) and theory/composition (jazz) and has done graduate work in theology. And he loves the novels of Tom Clancy and Michael Crichton.

    PDF Download • “For Pentecost Sunday”
    Yesterday morning, I recorded myself singing the ENTRANCE CHANT for Pentecost Sunday while simultaneously accompanying myself on the pipe organ. Click here to see how that came out. At the end of the antiphon, there’s a triple Allelúja and I just love the chord at the end of the 2nd iteration. The organ accompaniment—along with the musical score for singers—can be downloaded free of charge at the flourishing feasts website. For the record, the antiphon on Pentecost Sunday doesn’t come from a psalm; it comes from the book of Wisdom.

    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!

Quick Thoughts

    “Thee” + “Thou” + “Thine”
    Few musicians realize that various English translations of Sacred Scripture were granted formal approval by the USCCB and the Vatican for liturgical use in the United States of America. But don’t take my word for it! Here are four documents proving this, which you can examine with your own eyes. Some believe the words “Thine” and “Thou” and “Thee” were forbidden after Vatican II—but that’s incorrect. For example, they’re found in the English translation of the ‘Our Father’ at Mass. Moreover, the Revised Standard Version (Catholic Edition) mentioned in those four documents employs “Thine” and “Thou” and “Thee.” It was published with a FOREWORD by Westminster’s Roman Catholic Archbishop (John Cardinal Heenan).

    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.
