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.”

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!

    New Bulletin Article • “14 September 2025”
    My pastor requested that I write short articles each week for our parish bulletin. Those responsible for preparing similar write-ups may find a bit of inspiration in these brief columns. The latest article (dated 14 September 2025) discusses OFFERTORY ANTIPHONS and contains a wonderful quote by Archbishop Fulton J. Sheen.

    PDF Download • Draft Copy (Pamphlet)
    A few days ago, I posted a draft copy of this 12-page pamphlet with citations about the laity’s “full, conscious, and active participation.” Its basic point or message is that choir directors should never feel embarrassed to teach real choral music because Vatican II explicitly ordered them to do that! We’ve received tons of mail regarding that pamphlet, with many excellent suggestions for improvement. Please feel free to chime in!

    “Entrance Chant” • 23rd (Ordinary Time)
    This coming Sunday, 7 September 2025, is the 23rd Sunday in Ordinary Time (Year C). You can download the “Entrance Chant,” conveniently located at the feasts website. I also recorded a rehearsal video for it (freely available at the same website). The Communion Chant includes gorgeous verses in FAUXBOURDON. I attempted to create a rehearsal video for it, and it’s been posted at the feasts website, called by some: “church music’s best kept secret.”

Quick Thoughts

    Karl Keating • “Canonization Questions”
    We were sent an internet statement (screenshot) that’s garnered significant attention, in which KARL KEATING (founder of Catholic Answers) speaks about whether canonizations are infallible. Mr. Keating seems unaware that canonizations are—in the final analysis—a theological opinion. They are not infallible, as explained in this 2014 article by a priest (with a doctorate in theology) who worked for multiple popes. Mr. Keating says: “I’m unaware of such claims arising from any quarter until several recent popes disliked by these Traditionalists were canonized, including John XXIII, Paul VI, and John Paul II. Usually Paul VI receives the most opprobrium.” Mr. Keating is incorrect; e.g. Father John Vianney, several centuries ago, taught clearly that canonizations are not infallible. Archbishop Fulton J. Sheen would be another example, although clearly much more recent than Saint John Vianney.

    Vatican II Changed Wedding Propers?
    It’s often claimed that the wedding propers were changed after Vatican II. As a matter of fact, that is a false claim. The EDITIO VATICANA propers (Introit: Deus Israel) remained the same after Vatican II. However, a new set of propers (Introit: Ecce Deus) was provided for optional use. The same holds true for the feast of Pope Saint Gregory the Great on 3 September: the 1943 propers (Introit: Si díligis me) were provided for optional use, but the traditional PROPRIA MISSAE (Introit: Sacerdótes Dei) were retained; they weren’t gotten rid of. The Ordo Cantus Missae (1970) makes this crystal clear, as does the Missal itself. There was an effort made in the post-conciliar years to eliminate so-called “Neo-Gregorian” chants, but (contrary to popular belief) most were retained: cf. the feast of Christ the King, the feast of the Immaculate Conception, and so forth.

    Solemn “Salve Regina” (Chant)
    How many “S” words can you think of using alliteration? How about Schwann Solemn Salve Score? You can download the SOLEMN SALVE REGINA in Gregorian Chant. The notation follows the official rhythm (EDITIO VATICANA). Canon Jules Van Nuffel, choirmaster of the Cathedral of Saint Rumbold, composed this accompaniment for it (although some feel it isn’t his best work).
