Upon hearing the second movement of Haydn’s “Military” Symphony (No. 100), one critic wrote of the “hellish roar of war increasing to a climax of horrid sublimity!” It is difficult to fathom that this polite, classical symphony could be considered “hellish” and “horrid” sounding, conditioned as we jaded moderns are to music of a far more hellish affective character. Once you’ve heard Beethoven’s 9th, Götterdämmerung, The Rite of Spring, and 95% of new music since 1920 – not to mention the popular music spawn of hell, death metal – it is hard not to hear Haydn’s symphony as tame, even bordering on quaint. Have our ears changed that much in the intervening 200+ years since the Military Symphony debuted to rollicking success? In this regard, it has. The musical representation of fear, war, terror, and the enemy – what our 18th century reviewer called “horrid sublimity” – has morphed considerably from the contained Enlightenment aesthetic to today’s (post-)modern ethos, influenced as it is by expressionism, psychological realism, and Artaudian cruelty. Listening to Haydn’s symphony vividly demonstrates the historical variability of musical signs.
The first movement of the Military Symphony features a light, galloping rhythmic pattern (long-short-short) that is all energy, momentum, and drive. Affectively, the opening still carries strong connotations of a rousing adventure; it brings to mind “William Tell” and the “action music” sequences of the silent film era, conjuring images of square-jawed, bright-eyed men racing into the horizon on trusted steeds. There is a martial quality here as well, though not as blatant as in the next movement, which gives Symphony No. 100 its “Military” appellation.
As the allegretto opens, we get a sense that Haydn has eased back on the accelerator; while the first movement is full of motion and charge, this one begins with a moderately slow tempo and a dainty melody set to a dance-like rhythm. The theme is perfectly symmetrical, the very model of classical balance, and it conforms exactly to expectations; cadences are in the right places and harmonies move from one to the other in an orderly, predictable procession. Haydn is well known for his musical humor and his love of rhythmic tricks (think the “Surprise” Symphony, for instance), but there’s nothing at all unexpected about this opening. It is a portrait of musical civility and grace. And then come the Turks.
At 1:43, the C major of the placid opening is suddenly twisted into minor and the full ensemble enters forte with the opening material in the minor mode. There’s a Jekyll and Hyde element to this abrupt shift; it comes completely out of the blue, and with only one bar preparation (a descending minor triad in the low instruments), we go from the happy, stable ground of the opening to the invasion of the Ottoman army. Haydn draws upon an orchestrational novelty – an expanded battery of percussion instruments – to connote the Musselman hoards, particularly cymbals and triangle. It’s a wrenching transition, even to modern ears, although it must have been much more dramatic (and titillatingly terrifying) to the audiences of the late 18th century. The centerpiece of the movement, and indeed the whole symphony, is a gesture of musical orientalism, a portrait of the Other that is riddled with the semiotic codes of Turquerie (and let us not forget that Mozart dabbled in these codes as well). At 2:54, we’re back to the orderly, civilized opening theme in the major key, as if nothing had happened at all (or, if Dorothy was listening, “it was all just a dream!”). At 3:30, the percussion enters again, but the theme stays in the major mode. And at 4:43, another signifier of the military enters into the evolving musical narrative in a form of a (positively Mahlerian) solo bugle call. It seems the armies of Europe, and thus civilization, are on the march! At 4:55, the bugle cuts out and we hear a timpani roll crescendoing into a fortissimo Ab major (C in the bass), with full percussion support. This din is the “climax of horrid sublimity” referred to by the reviewer. Sabers rattle around us as we clash with the enemy in battle.
Haydn represents the enemy in this movement by means of musical exoticism. By dipping into the semiological pool of Turkish signifiers, he is able to tap into late 18th century anxieties about invaders from the south. The threat is presented, then promptly neutralized; we end the movement with full percussion, but all the fight has been drained from it, and it seems only to reinforce the opening materials, which serve as a musical representation of civility. There are two points during this movement that register the highest level of terror: when the Turkish percussion first enters and the melody suddenly lurches into the minor mode; and towards the end, when blaring tutti in a new key and rolling timpani (which was then considered a novel technique) conspire to make a warlike noise. In both instances, the threat quickly subsides. The enemy is safely contained.
At the heart of the difference between 18th century and modern representations of terror and the enemy is the question of aesthetic distance. There is a certain aloofness to the classical style; although Haydn shows us the raging Turks, he does so from a distance, placing a frame around the object of horror and allowing us to view the threat from afar, like zoo-going spectators watching the roaring lion from behind the reassuring comfort of a plexiglass wall. Audiences didn’t find the Military Symphony allegretto terrifying; they found it “deliciously terrifying.” In other words, they always remembered that they were listening to a symphony, not a band of wild Turks; there was always a marked distinction between representation and reality. As Mozart put it in an oft-quoted letter, “music, even in the most terrible situations, must never offend the ear, but must please the listener, or in other words must never cease to be music.”
Here, in a nutshell, is the Enlightenment aesthetic of distance. A handful of years later, Kant published his Critique of Judgment, with its notion of “disinterested interest,” a classic formulation of this aesthetic principle. Terror and other extreme states were meant to be observed from a comfortable distance, not actually experienced. Both classical and modern representations of musical terror deal in the sublime, not in today’s sense of the word as “beauty,” but in the classical, Enlightenment understanding of the term – as overwhelming “awe.” Yet the sublime is a moving target historically. What was “horrid sublimity” to Haydn and his contemporaries is practically cute today. The horror of warfare remains today what it was millennia ago; brutal, nauseating, and dumb. The way we represent these eternal conditions through music and the way we listen to sublime terror, however, have shifted profoundly since the 18th century. Terror itself is a universal; we just deal with it in different ways at different times. In Haydn’s day, the roaring lion would have been shot, taxidermized, and displayed for the public to gawk at; today, many people spend good money to view lions in person on safari. The lion is the same – the distance has changed.
