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.”

Glancing at Eurydice: Why Read Medieval Theory?

Dr. Charles Weaver · October 2, 2024

HERE’S SOMETHING that happens to teachers every autumn, and it has certainly been true of me this year. The academic term starts up with infinite promise, and all of a sudden we look up, emerging from the inevitable chaos that ensues, and see that it is October. I’m teaching a lot of new material this year (including lots of Baroque plainchant), and I have many new students, who are very inquisitive and very engaged. I’ve been so wrapped up in teaching that I’ve done precious little reading or writing. It would probably be better if we all were able to take a little time to do some musical reading and reflection that wasn’t pointed directly at the task at hand, whether teaching or putting music together for the parish schola.

Recently, when I had finally settled down to do some reading aimed more at the long term (Daniel Saulnier’s last book on the modes), I came across a quotation from Musica enchiriadis, (ME), that took my breath away and got me thinking about how much value there is in just poking around in old books about music, without trying to read with a specific agenda. ME, whose title means something like The Music Handbook is one of the ninth century treatises that is foundational in medieval music theory. Usually we learn about this book for its discussion of improvised polyphony (organum). But the last chapter is striking and is easy to gloss over. Here is the text of the first part of that chapter in Raymond Erickson’s very readable English translation, which is mostly available only in libraries now:

The ancients tell that Aristeus was in love with the nymph Eurydice, spouse of Orpheus. While fleeing her pursuer (Aristeus), she was killed by a snake. We perceive an Orpheus whose name signifies oreo phone—“the best voice”—in a skilled singer (cantor peritus) or in sweet-sounding melody. If any “good man,” as Aristeus may be translated, pursues Eurydice—that is, “profound understanding”—out of love, he is hindered by divine wisdom, lest she be entirely possessed, as if by the snake. But while she in turn is called forth from her hidden places and from the underworld by Orpheus, that is, by the most noble sound of song, she is seemingly led up into the atmosphere of this life and, as soon as she seems to be seen, is lost.
 
So, as in other things that we discern only partly and dimly, this discipline does not at all have a full, comprehensible explanation in this life. To be sure, we can judge whether the construction of a melody is proper and distinguish the qualities of tones and modes and the other things of this art. Likewise, we can adduce, on the basis of numbers, the musical intervals or the symphonies of pitches and give some explanations of consonance and dissonance. But in what way music has so great an affinity and union (commutatio et societas) with our souls—for we know that we are bound to it by a certain likeness—we cannot express easily in words.

What’s going on here? We’ve been reading about some technicalities of organization (in the organic organum sense!), and all of a sudden we are wrenched into this work of Greek mythology. You probably know the Orpheus myth from Ovid, or perhaps from the splendid operatic treatments by Monteverdi, Charpentier, or Gluck. The semi-divine Orpheus wins the love of the fair nymph Eurydice, but on their wedding day she is bitten by a snake and dies. Orpheus journeys to the underworld and uses his amazing musical prowess to win over the inhabitants to his cause, convincing Pluto, the god of the underworld, to release Eurydice, on the condition that Orpheus walk in front of her and that he not look back until he reaches the upper world again. But he is plagued by doubt and ends up looking back too soon, only to see her vanish forever.

The author of ME uses this story not to create an operatic spectacle but rather an exegetical one, for he reads the story allegorically. Here, Eurydice stands for understanding—in this context, we might say musical understanding. Have you ever noticed how hard it is to speak about the actual experience of music? This is the theme of a book (Music and the Ineffable) by a very different philosopher from the twentieth century, Vladimir Jankélévitch. The idea is simple and practically irrefutable: whenever we try to talk about music, we run up against something that defies being put into words, so we end up resorting to all kinds of metaphors that utterly fail to capture the experience of actually hearing music. Jankélévitch calls this our alibi. We might talk about the composer, the composer’s mood, the composer’s personal life, the social and historical of a particular piece and how it is reflected in the music. To take it a little bit closer to home for the theory teacher, we might talk about the formal structure, the melodic or harmonic design, the various spatial metaphors (high, low, deep, leaping, stepwise, running), all of which fail in some way. I believe the author of ME is saying much the same thing, and it’s a good lesson.

We can listen to music, or we can also read about music, in this case, chant and its modes and its melodic designs. But to try to use these things to bring about perfect understanding is to try to bring Eurydice (wisdom) up into the light of day, which the gods will not suffer us to do. “We discern only partly and dimly,” which is as true when we sing as when we read about music or try to work out how a piece of chant is put together, or even when we wade into the deep waters of modal ethos. We don’t hear the chant as God does, but He allows us to have just a fleeting glimpse (the “Best voice’s” backward glimpse at “perfect understanding” as she recedes into the bowels of the earth) when we sing, by way of the mysterious affinity that music has for our souls.

I was so touched to see that an author in the ninth century so perfectly captured this experience of those precious, rare mental/aural glimpses of true understanding we all have occasionally when we hear or sing Gregorian chant. To me, it is passages like that that make the ancients’ writings so worthwhile to read and teach. It’s also heartening for those of us who spend our time teaching to bear this in mind, especially as we do our best to impart some of our limited and imperfect understanding to our students.

    Music List • (Holy Thursday, 2026)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for Holy Thursday, which is 2 April 2026. If such a thing interests you, feel free to download it as a PDF file. I’m not sure I’ve ever heard a more piercingly beautiful INTROIT, and I have come to absolutely love the SATB version of ‘Ubi cáritas’ we are singing (joined by our burgeoning children’s choir). I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

    “O Escam Viatorum” • (Holy Thursday)
    When I was very young, I erroneously believed the four psalms provided by the 1957 Liber Usualis—for Communion on Holy Thursday—were the “correct” music to sing on that first day of the TRIDUUM SACRUM. Those four psalms are: Psalm 22 (Dóminus regit me et nihil mihi déerit); Psalm 71 (Deus judícium tuum regi da); Psalm 103 (Bénedic ánima méa); and Psalm 150 (Laudáte Dóminum in sanctis ejus). It turns out I was way out in left field! While nothing forbids singing those psalms, many other options are equally valid. Our volunteer parish choir will sing this COMMUNION PIECE (joined by our burgeoning children’s choir) on Holy Thursday during Holy Communion. Needless to say, this will happen after the proper antiphon from the GRADUALE ROMANUM has been sung.

    Music List • (4th Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 4th Sunday of Lent (15 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has sublime propers. It is most often referred to as “Lætare Sunday” owing to its INTROIT. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

Quick Thoughts

    Stumped by “Episcopalian Hymnal” (1910)
    Some consider Songs of Syon (1910) the greatest Episcopalian hymnal ever printed. As a Roman Catholic, I have no right to weigh in one way or the other. However, this particular page has me stumped. I just know I’ve heard that tune somewhere! If you can help, please email me. I’m talking about the text which begins: “This is the day the Lord hath made; In unbeclouded light array’d.” The book is by George Ratcliffe Woodward, and its complete title is: Songs of Syon: A Collection of Psalms, Hymns, and Spiritual Songs. Back in 2016, Corpus Christi Watershed scanned and uploaded this insanely rare book. For years our website was the sole place one could download it as a PDF file.

    “Dies Irae” • A Monstrous Translation
    It isn’t easy to determine what Alice King MacGilton hoped to accomplish with her very popular book—A Study of Latin Hymns (1918)—which continued to be reprinted in new editions for at least 34 years. This PDF file shows her attempt to translate the DIES IRAE “in the fewest words possible.” There’s a place for dynamic equivalency, but this is repugnant. In particular, look what she does to “Quærens me sedísti lassus.”

    PDF Download • “Holy, Holy, Holy”
    For vigil Masses on Saturday (a.k.a. “anticipated” Masses) we use this simpler setting of the “Holy, Holy, Holy” by Monsignor Jules Vyverman (d. 1989), a Belgian priest, organist, composer, and music educator who ultimately succeeded another ‘Jules’ (CANON JULES VAN NUFFEL) as director of the Lemmensinstituut in Belgium. Although I could be wrong, my understanding is that the LEMMENSINSTITUUT eventually merged with “Catholic University of Leuven” (originally founded in 1425). That’s the university Fulton J. Sheen attended.

Random Quote

“Just before he left Letchworth, as he well knew to meet his death, he turned and bade good-bye to his little church, and silently kissed the altar-stone on which he had so frequently offered Mass.”
