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.”

Andrea Leal · November 21, 2019

80768 sperabo NE OF THE challenges of a small choir is having enough singers to pull off any kind of polyphony. Last year I came across a series of Advent motets by Deigo de las Muelas (1698-1743). He was a Spanish composer who served as the “maestro de capilla” for the cathedrals of Astorga and Santiago de Compostela. The original voicing for the 1st Sunday in Advent (“Erunt Signa in Sole”) is for SATB. However, last year this was not something we could have managed. Therefore, I studied the music (briefly, because I do everything with multiple children hanging from each of my limbs) and arranged it for SAT. If you have enough voices for SATB, the original can be found on cpdl.

I recorded each of the parts for my choir last year. Perhaps these tracks will be useful to some of you with smaller volunteer choirs this Advent:

Our YouTube channel has rehearsal videos for each individual voice. You can see where the text comes from by downloading the 1st Sunday of Advent and looking at the Gospel:

(Luke 21:25)

Et erunt signa in sole, et luna, et stellis,
et in terris pressura gentium
præ confusione sonitus maris, et fluctuum…

The sun and the moon and the stars will give portents,
and on earth the nations will be in distress,
bewildered by the roaring of the sea and of its waves…

Remember that 99% of the people attending Mass on Sunday have no idea what it “ought” to sound like. Music scholars might need their smelling salts and a fainting couch when they hear about this guerrilla tactic, but if you have to reduce an SATB piece to just SA, ST or SB, then do it. This will help you get started in singing some polyphony until your choir’s abilities progress. You can still pull off something pleasing to the Lord that is worlds better than a typical jingly jangly modern hymn. It is true that some pieces of music cannot be reduced because they simply lose too much beauty in the harmonic progression of the chords. This is a judgement call you will have to make.

If you just aren’t sure it will work, use your phone to record your choir singing the reduced version of whatever amazing polyphonic piece you want to try. Then let a friend, co-worker, family member, or Sharon from the soccer carpool take a listen. If they hear it and make a face like they just bit into a lemon, then fine—maybe it won’t work. But if they find it pleasant to listen to, then press on. Gloria in excelsis Deo!

Background For This Article

Anyone who has built a choir from the ground up knows that there are some things that simply cannot be circumvented no matter how badly you want to. For example, singing the full propers when your volunteer choir is just starting out is virtually impossible. So you rely on psalm tone propers and try to learn one or two full chants a month. You build from there, and every year you add to the repertoire until one day you find that your choir is not only capable of singing all of the propers for the year in full, they can even sight sing Gregorian chant. But this does not happen overnight. The process can take years. It is not for the faint of heart or the impatient soul! There are a myriad of obstacles along the way, not the least of which is sometimes…you. As music directors we are limited by our imperfections and our own gaps in knowledge. Sometimes, we are learning right alongside choir members—and that’s ok. Maybe you got thrown into the position by default because there was no one else who was remotely capable of leading a choir. I know there are a lot of music directors reading this right now who have minimal formal musical training, if any. Maybe “music director” is even too lofty a title for what you do (this is definitely true of me). You are out there, trying your best to build up something beautiful and sacred that will befit the Holy Sacrifice of the Mass. You might be in it virtually alone, but you desperately want to help draw souls to Christ. And it’s hard. I know because I am right there with you.

We have seen many articles on this website of incredible scholarly insight. We have heard from the absolute best professionals in sacred music. We have benefited tremendously and soaked up every bit of knowledge offered. And now…you get to go slumming with me! Over the next few months, I will humbly offer some of the “guerrilla tactics” in sacred music that I have learned along the way. This is for all you church musicians who just got thrown into the pool even though you didn’t know how to swim. Sometimes, we are going to make the rules up as we go along. But this is always in order to glorify God as deeply as we know how. We are going to pull ourselves up by the bootstraps and make it happen!

    Simplified Accompaniment (Easter Hymn)
    Number 36 in the Brébeuf Hymnal is “At the Lamb’s high feast we sing,” an English translation for Ad Cenam Agni Próvidi (which was called “Ad Régias Agni Dapes” starting 1631). As of this morning, you can download a simplified keyboard accompaniment for it. Simple click here and scroll to the bottom. Many organists are forced to serve simultaneously as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult—which explains why choirmasters appreciate these simplified keyboard accompaniments. Sadly, many readers will click that link but forget to scroll to the bottom where the simplified PDF file is located.

    PDF Download • “Quasi Modo Sunday”
    The Introit for “Quasi Modo Sunday” (12 April 2026) is particularly beautiful. The musical score can be downloaded as a PDF file, and so can the organ accompaniment. The official language of the Catholic Church is Latin (whereas Greek is our mother tongue). Vatican II said Gregorian Chant must be given “first place” under normal circumstances. As a result, some parishes will rightly sing the authentic version. On the other hand, because so many USA dioceses disobey the mandate of Vatican II, some musicians sing plainsong in the vernacular. I have attempted to simultaneously accompany myself on the pipe organ while singing the English version. Although very few take advantage of it, the complete Proprium Missae is posted at the flourishing feasts website.

    ‘German’ Introductions for Hymns
    German organ books have an enchanting habit of including introductions for each and every hymn. For example, consider this snazzy example found in a German hymnal published in 1902. In the Saint Jean de Brébeuf Hymnal, that melody is called “Laudes Mariae” and was married to Omni Die Dic Mariae, with a popular English translation (“Daily, daily, sing to Mary”) by Father Henry Bittleston, an Oratorian priest. Notice they also added a ‘tailpiece’ or ‘playout’ or postlude at the end—a very German thing to do!

Quick Thoughts

    PDF • “Liturgical Law” (467 Pages)
    On Good Friday during the middle ages, the pope privately recited THE ENTIRE PSALTER. If you don’t believe me, see for yourself by reading this passage by Dom Charles Augustine Bachofen (d. 1943). His famous book—called “Liturgical Law: A Handbook Of The Roman Liturgy”—was published by the Benjamin Herder Book Company, which was the American arm (operating out of St. Louis, Missouri) of one of the world’s most significant Catholic publishers. Dom Charles Augustine Bachofen was born in Switzerland but spent his career between the Benedictine monasteries at Conception (Missouri) and Mount Angel (Oregon). His 1931 masterpiece, Liturgical Law can be downloaded as a PDF file … 467 pages!

    “Gregorian Chant Quiz” • 24 March 2026
    How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!

    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.

Random Quote

“Church officials frequently asked Tomás Luis de Victoria for his opinion on cathedral appointments because of his fame and knowledge. He was faithful to his position as convent organist even after his professional debut as an organist, and never accepted any extra pay for being a chapelmaster. Held in great esteem, his contract allowed him frequent travel away from the convent, and he attended Palestrina’s funeral (in Rome) in 1594.”

— ‘Dr. Robert Stevenson, 1961 (mod.)’
