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.

    “Holy Name Hymn” (2-Voice Arrangement)
    When we post a direct URL link, we frequently get thousands of downloads. But when scrolling is required, very few take the time. I mention this because those who click on this URL link and scroll to the bottom can download—completely free of charge—a clever 2-voice arrangement for a famous hymn to the Most Holy Name of Jesus. In a pinch, it can be nicely sung by one male and one female! It will be of interest to those who seek arrangements for two voices.

    PDF Download • Introit (3rd Sn. Ord.)
    This coming Sunday, 25 January 2026, is the 3rd Sunday in Ordinary Time (Year A). The ENTRANCE CHANT (“Dóminus secus mare”) is somewhat rare because it comes from the New Testament. The authentic version in Latin—of astounding antiquity—was jettisoned in 1955 but restored in 1970. This rehearsal video has me attempting to sing the melody while simultaneously accompanying myself on the organ. I encourage you to print off the organ accompaniment (PDF) and play through it because it has extremely ‘happy’ harmonies.

    “Lamb of God” (Musical Setting)
    The MASS OF SAINT ANNE LINE has been quite popular ever since ROMAN MISSAL Third Edition was released circa 2011. You can now download the musical score (PDF) for this setting, placed into five (5) different keys; i.e. “pitch levels” that are high and low. This makes it possible to adjust based upon who’s singing at which time of day.

    “Reminder” — Month of January (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. Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

    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.
    —Jeff Ostrowski
    PDF Download • “In Paradisum” in English
    We always sing the IN PARADISUM in Latin, as printed on this PDF score. I have an appallingly bad memory (meaning I’d be a horrible witness in court). In any event, it’s been brought to my attention that 15 years ago I created this organ accompaniment for the famous and beautiful ‘IN PARADISUM’ Gregorian chant sung in English according to ‘MR3’ (Roman Missal, Third Edition). If anyone desires such a thing, feel free to download and print. Looking back, I wish I’d brought the TENOR and BASS voices into a unison (on B-Natural) for the word “welcome” on the second line.

Random Quote

“I have, on the other hand, retained several more or less traditional tunes, absolutely valueless and without merit from a musical point of view, but which seem to have become a necessity if a book is to appeal—as I hope this one will—to the varied needs of various churches.”

— A. Edmonds Tozer (1905)
