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!

President’s Corner

    Luis Martínez Must Go!
    Sevilla Cathedral (entry dated 13 December 1564): The chapter orders Luis Martínez, a cathedral chaplain, to stay away from the choirbook-stand when the rest of the singers gather around it to sing polyphony—the reason being that “he throws the others out of tune.” [Excerpt from “The Life of Father Francisco Guerrero.”]

    “Booklet of Eucharistic Hymns” (16 pages)
    I was asked to create a booklet for my parish to use during our CORPUS CHRISTI PROCESSION on 22 June 2025. Would you be willing to look over the DRAFT BOOKLET (16 pages) I came up with? I tried to include a variety of hymns: some have a refrain; some are in major, others in minor; some are metered, others are plainsong; some are in Spanish, some are in Latin, but most are in English. Normally, we’d use the Brébeuf Hymnal—but we can’t risk having our congregation carry those heavy books all over the city to various churches.

Quick Thoughts

    Pope Pius XII Hymnal?
    Have you ever heard of the Pope Pius XII Hymnal? It’s a real book, published in the United States in 1959. Here’s a sample page so you can verify with your own eyes it existed.

    “Hybrid” Chant Notation?
    Over the years, many have tried to ‘simplify’ plainsong notation. The O’Fallon Propers attempted to simplify the notation—but ended up making matters worse. Dr. Karl Weinmann tried to do the same in the time of Pope Saint Pius X by replacing each porrectus. You can examine a specimen from his edition and see whether you agree he complicated matters. In particular, look at what he did with éxsules fílii Hévae.

    Antiphons Don’t Match?
    A reader wants to know why the Entrance and Communion antiphons in certain publications deviate from what’s prescribed by the GRADUALE ROMANUM published after Vatican II. Click here to read our answer. The short answer is: the Adalbert Propers were never intended to be sung. They were intended for private Masses only (or Masses without music). The “Graduale Parvum,” published by the John Henry Newman Institute of Liturgical Music in 2023, mostly uses the Adalbert Propers—but sometimes uses the GRADUALE text: e.g. Solemnity of Saints Peter and Paul (29 June).

Random Quote

Thus the priest-celebrant, putting on the person of Christ, alone offers sacrifice, and not the people, nor clerics, nor even priests who reverently assist. All, however, can and should take an active part in the Sacrifice. “The Christian people, though participating in the Eucharistic Sacrifice, do not thereby possess a priestly power,” We stated in the Encyclical Mediator Dei (AAS, vol 39, 1947, p. 553).

— Pope Pius XII (2 November 1954)
