Sacred Music Colloquium XXV — Update I

Andrew Leung · June 29, 2015

T IS GREAT TO BE HERE. It is great to be in Pittsburgh for the twenty-fifth Sacred Music Colloquium organized by the Church Music Association of America. This meeting is not only an academic conference and spiritual retreat, but also a great time to hang out with old friends and meet new ones. In the coming few days, I will be posting a report at the end of each day for friends who are not able to participate the Colloquium this year.

ONIGHT, Dr. William Mahrt, President of the Church Music Association of America, delivered his welcoming speech at the dinner. He gave an introduction on what we will be doing at this Colloquium. He mentioned the three characteristics of Sacred Music from Pope St. Pius X’s Tra le Sollecitudini: Sacred, Beautiful and Universal. He told us that we are about to experience the sacredness and beauty of the Church’s music, especially Gregorian Chant and Classical Polyphony. The aim of the Colloquium is that the participants, who will experience the sacredness and beauty of Sacred Music, will go out to the world and make it universal.

In his speech, Dr. Mahrt also talked about the Liturgies that we will be participating this week. He mentioned about the Liturgy of the Hours, he said, “We must pray the Liturgy of the Hours as the Liturgy of the Hours”. Which means that we need to pray it throughout the day. Dr. Mahrt also said that we should reflect on the relationship between the Ordinary Form and the Extraordinary Form of the Roman Rite. Masses will be celebrated in both Forms this week: once in English Novus Ordo, twice in Latin Novus Ordo and twice in Vetus Ordo.

FTER THE OPENING DINNER, we had the pleasure of hearing Dr. Ann Labounsky’s special recital on the newly-installed pipe organ in the Duquesne Chapel. The recital featured mainly French pieces, which is what Dr. Labounsky is known for, and ended with a wonderful improvisation on two themes (King’s Weston tune or “At the Name of Jesus”, and the simple tone Salve Regina) submitted by Dr. Mahrt. We ended the night with the Compline sung by almost two hundreds participants. It was truly a powerful prayer and moving experience.

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.
