Motet for Three Voices: “O Crux Ave”

Fr. David Friel · January 24, 2016

HE SPACE between Christmas and Lent never seems as long as we expect (or would like). Preparations for Lent and Holy Week have already begun in many parishes, with Ash Wednesday looming on February 10th. Time is therefore precious at upcoming choir rehearsals.

On Friday, Richard Clark offered links to a number of resources he has published for Lent and Easter. Today, allow me to offer a link to a composition of my own.

Available through CanticaNOVA Publications, my setting of O Crux, Ave is written for three voices. The range is limited enough that it can be sung by equal voices (either men or women) or by a mixed choir (SAB).

This piece is ideal for use as a motet during the veneration of the Holy Cross at the Good Friday liturgy. Its structure with optional verses allows the piece to be limited or extended, as necessary, while its text focuses attention on the majesty of the Holy Cross. The text is actually a splicing of a phrase from the Exsultet with a line from the Passiontide hymn, Vexilla Regis prodeunt.

O Crux Ave can also be sung at any point in Passiontide (from the Fifth Sunday of Lent through Good Friday) or on the feast of the Exaltation of the Holy Cross (September 14th). This piece, which can be ordered here, is an easy, go-to piece for choirs to use any time there is a focus on the Holy Cross or the mystery of salvation.

PDF Download • “Ubi Caritas” (SATB)

I remember singing “Ubi Cáritas” by Maurice Duruflé at the conservatory. I was deeply moved by it. However, some feel Duruflé’s version isn’t suitable for small choirs since it’s written for 6 voices and the bass tessitura is quite low. That’s why I was absolutely thrilled to discover this “Ubi cáritas” (SATB) for smaller choirs by Énemond Moreau, who studied with OSCAR DEPUYDT (d. 1925), an orphan who became a towering figure of Catholic music. Depuydt’s students include: Flor Peeters (d. 1986); Monsignor Jules Van Nuffel (d. 1953); Arthur Meulemans (d. 1966); Monsignor Jules Vyverman (d. 1989); and Gustaaf Nees (d. 1965). Rehearsal videos for each individual voice await you at #19705. When I came across the astonishing English translation for “Ubi Cáritas” by Monsignor Ronald Knox—matching the Latin’s meter—I decided to add those lyrics as an option (for churches which have banned Latin). My wife and I made this recording to give you some idea how it sounds.

PDF • “Cantus Mariales” (192 pages)

Andrea Leal has posted an absolutely pristine scan of CANTUS MARIALES (192 pages) which can be downloaded as a PDF file. To access this treasure, navigate to the frabjous article Andrea posted Monday. The file is being offered completely free of charge. The beginning pages of the book have something not to be missed: viz. a letter from Pope Saint Pius X to Dom Pothier, in which the pope calls Abbat Pothier “a man versed above all others in the science of liturgy, and to whom the cause of Gregorian chant is greatly indebted.”

Music List • (2nd Sunday of Lent)

Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 2nd Sunday of Lent (1 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has magnificent propers. Its somber INTROIT is particularly striking—using a haunting tonality—but the COMMUNION with its fauxbourdon verses is also quite remarkable. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

Extreme Unction

Those who search Google for “CCCC MS 079” will discover high resolution images of a medieval Pontificale (“Cambridge, Corpus Christi College, MS 079”). One of the pages contains this absolutely gorgeous depiction of the Sacrament of Extreme Unction.

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.
