Views from the Choir Loft

A Dramatic Moment

Jeff Ostrowski · September 10, 2018

At the Traditional Latin Mass, a dramatic moment happens on Holy Saturday Night. Three things return all at once: the BELLS, the GLORIA, and the ORGAN.

Somebody took a video of our ceremony on 31 March 2018:

I whispered to the organist (Ethan Haman) what was required, and somehow he knew exactly what I needed from him. If the singing voices sound strained, remember that this ceremony was three hours long—in the middle of the night! I hope to divide the choirs next year, so that a single choir is not responsible for Palm Sunday, Holy Thursday, Good Friday, Holy Saturday, and Easter Sunday. The priests shown in the video are members of the Priestly Fraternity of Saint Peter. The FSSP recently dedicated a church in the Archdiocese of Los Angeles, called Saint Vitus.

The 1962 Missal—fully approved by the Catholic Church—is known as the Extraordinary Form. Starting in 2007, no priest of the Latin Rite needs permission from the bishop to offer this ancient rite. Our FSSP parish had permission from Rome this year to use the pre-1955 Holy Week, as I have explained.

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.

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.
