Leo Spitzer, in his “historical semantics” on Classical and Christian Conceptions of World Harmony, explains that Ambrose’s composition of the first hymn focused on world harmony was something that only a Christian theology could have produced. While Hebraic music seemed uninterested in the concept of world harmony, Greek music seemed to believe world harmony couldn’t be imitated in human music at all.
World harmony, the ability to at once “express best the inner depths of human and cosmic nature”, was for the Greeks not only “inaccessible to human ears” but also purely metaphorical. Or, rather, human music was a metaphor for the universal music, but its purpose was purely a spiritual one, to understand the creator (poietes, a poet/musician) and to put one’s soul in healthy order (an idea Spitzer says later attracted Augustine). Thus music is central to Plato in the Republic because of the close relationship of harmony to the soul and the soul to the polis. “Plato establishes the parallel: individual body—individual soul—polis, all three being predicated on order and temperance. There is in man himself a politeia, which bids him attune his body to the harmony of his soul, ‘if he has true music in him’….”
The idea of world harmony, Spitzer points out, is attractive to early Christian thinkers because there is some resonance with passages of Scripture (Job 38:7, Liber Sapientiae 19:17, both of which are connected by later thinkers to concentum caeli and in organo qualitatis sonus). He doesn’t find it surprising, then, that Ambrose would make the connection fully clear in his Hexaemeron, a vision of Christian world harmony syncretized with Pythagoras. But Ambrose’s conception is nuanced or fulfilled. Although it’s quite true that “a human simile can give but a slight reflection of the consonance of the concentus undarum with the concentus plebis,” it’s also true that Christian singing can really be a worthy reflection of world harmony—in fact, even a better one that Greek speculation on it. “The Greeks, on the other hand, ascribed to music the highest place in the universe; and yet, though we are indebted to them for much philosophical speculation about music, it could be said that they have left us comparatively little of the music which should illustrate their philosophy. But in the hymns of Ambrose, we have a ‘performance,’ an ‘incarnation’ of that world harmony about which the Greeks had speculated; and the Church, which was represented in his hymns as echoing the music of the universe, served, actually, as the theater for the performance of these hymns (as it was to serve later as the original state of medieval drama).”
Ambrose, according to Spitzer, gets the “immortal merit…to have assigned to Christian music the task of embodying the Greek world harmony,” and not the ancient Israelites in their Psalms. “The Psalms were full of musical elation in praise of God, but the idea of world harmony was only potentially present; their radiant and resounding similes were symbolic only of the inner wealth of a religious feeling: pictures conjured up to figure the unspeakable.” Certainly it seems like Spitzer’s assessment here is unfair and sloppy. Pictures conjured up to figure the unspeakable sounds like an excellent description of another religion’s music and poetry. And it seems that plenty of Psalms and Hebraic music (19 and 87, the Song of Moses, off the top of my head) would admit a world harmony idea pretty clearly.
But at the same time it’s easy to fall into a trap of feeling the need to find Greek philosophy in the Old Testament, a trap that many thinkers past and present seem to fall into when dealing with world harmony and musica mundana. A fierce desire to make musica mundana a Scriptural idea would presuppose that it ought to be there, merely to fit our Hellenic standards of beauty. The Timaeus is an awfully nice thought, but it is just a thought and it would be silly to wish David and Moses had thought and talked more like Plato. And yet this is what it seems many Medieval authors wished when they spoke of music. I’m content with the thought that Ambrose’s attempt to embody this world harmony would have scandalized the Greeks and struck them as a rash, overly bold and probably blasphemous. You go, Ambrose. Scandalize those stupid Pythagoreans.
