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.”

Views from the Choir Loft

Choir Rehearsal Is Prayer

Richard J. Clark · February 13, 2015

O I JUST FINISHED directing one of the most enjoyable choir rehearsals in quite some time. That is saying a lot because I usually feel highly energized by choir rehearsals. No matter how early in the morning my five year old and/or eleven month old sons wake me up, by the end of a choir rehearsal, I’m flooded with endorphins and can’t sleep — like right now. Ironically, it is quite possible we won’t get to sing the music we rehearsed — a problem everyone in Boston is facing this Sunday.

Oh, it was not the best sounding rehearsal by far. Many, including some of my best singers were unable to attend in part because of the 72” (182.88cm) of snow on the ground in Boston. It seems we are due for another 10-18” on early Sunday morning—the fourth major storm in three weeks. This annoys me. Why does it have to hit Saturday evening into Sunday morning? Even late Sunday morning works for me. I’ll figure out how to get back later. Oh, I almost forgot, I learned the National Guard was in front of my house during tonight’s rehearsal removing snow. I already got work without them. In fact my choirs have been showing up in surprisingly wonderful numbers despite all the recent snow.

I digress.

HIS WAS ONE OF THE BEST REHEARSALS because my volunteers, including two new singers this week, accomplished a great deal in their own right. They beautifully learned the Introit, Esto mihi in Deum protectorem from the Graduale Romanum, choral anthems for Sunday and Ash Wednesday, a beautiful psalm setting by Jeff Ostrowski (one of his best, Psalm 32), a communion proper, etc., etc. Without some of my best singers and many others missing, they responded thoughtfully and sensitively to correction and direction. New singers weren’t completely freaked out by trying to sing Gregorian notation, despite a lack of experience. They tackled various styles, as always, imbuing reverence and nuance. As such, the more I respect a choir’s ability, the more critical I am in rehearsal. I was very critical, and I was very proud of them.

I think many of us are lucky to experience this in choir rehearsal. While we left knowing Sunday’s weather forecast looked dire, I told them I was grateful for this time together in prayer. Rehearsal is prayer. These great texts of the church are prayer. Hopefully, the music we add is sacred, beautiful, and therefore, universal.

Snow annoys me, because selfishly, I’d like to implement what we so lovingly prepared. It may end up being that the prayer of rehearsal will have to be good enough this week. One of the best rehearsals ever might be followed up by a fizzle.

But it won’t be. I am deeply grateful for the beautiful people around me who also want to serve the Church and each other. This will live on in our hearts with more music to pray.

    Dom Pothier • Photo from 1904
    Dom Paul Cagin, in a 1904 publication (L’oeuvre de Solesmes dans la restauration du chant grégorien) made sure to include a beautiful image of Dom Pothier, the legendary abbot of St-Wandrille. Also shown is a very young Dom André Mocquereau. Auguste Pécoul—considered the spiritual “son” of Abbat Prosper Guéranger of Solesmes—wrote as follows on 24 June 1901: “To forestall any confusion, let us remember that there is just one Gregorian notation—that restored, according to the ancient manuscripts, by the eminent Abbot of Saint-Wandrille, Dom Pothier.” ✠

    PDF • “3-Voice Motet” (Father De Laet)
    I believe 99% of our readers will recognize this hymn tune. Perhaps Father Edgard De Laet should have called it a ‘hymn’ instead of a ‘motet for three voices’—but he’s technically correct, since MOTET is defined as: “a short piece of sacred choral music, typically polyphonic and unaccompanied.” The even verses are for three voices, as you will see if you download the PDF score at #20245. The odd verses may be song a cappella SATB or unison with organ.

Quick Thoughts

    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.

Random Quote

“Gregorian chant is the sacred chant, proper and principal of the Roman Church. Therefore, not only can it be used in all liturgical actions, but unless there are mitigating circumstances, it is preferable to use it instead of other kinds of sacred music.”

— “De musica sacra et sacra liturgia” (3 September 1958)
