For the last few years, I’ve been having conversations about music with AI large language models (LLMs) in whatever flavor was most easily accessible to me – Gemini, Bard before that, Copilot. (I even did a TED talk about one experience: https://www.youtube.com/watch?v=eVhl6djXnGM) It seems inevitable, then, having embarked on this Haydn project, that I would eventually ask AI what it thought about one of the symphonies.
I admit to having had fun during these AI conversations, even lots of fun at times, and I’ve been anywhere from almost satisfied to genuinely charmed by answers I’ve received or exchanges I’ve had. A handful of times I’ve even been truly excited, have been led to something I would only have come to on my own through considerably greater effort and gobs of time. Though, I should note, those revelations have never once been about music.
In fact, the thing that has disappointed me, again and again, is that, as far as I can tell, LLMs cannot read music notation and, much more nefariously, that they persistently claim to have that capability. That’s what’s called a lie when humans do it. I’m unsure what to call it in the absence of an ethical impulse, in a shame vacuum, when a program does it. A programming error, or a systemic flaw, perhaps. Nevertheless, for the human reading it, it feels and, if I’m to be honest, stings like a lie.
In preparing to write this entry I had initially thought it might be simplest just to share the transcript of my midsummer conversation with Copilot about Haydn’s Third and Fourth Symphonies. Who wants to read through a whole transcript, though, with its salutations and side quests? So, I’ll mostly provide a summary, colored by a few illustrative quotes.
Oh. I should explain the title of this entry. Nerdly Confession: I had asked Copilot to try to answer my questions about Papa Haydn in language resembling the Robert Heinlein of, say, The Moon Is a Harsh Mistress, because… why not? And you know what? Copilot did a pretty fair job, as witness this gratifying construction: “What’s the trajectory here? Are we tracing thematic development across centuries? Drawing parallels between Enlightenment structure and lunar rebellion? Or maybe you’re composing a fugue of ideas–Haydn in the exposition, Heinlein in the development, and something entirely your own in the recapitulation? Whatever it is, I’m with you. Let’s fly.”
Not so bad, right?! Fun, at the very least, though hardly as intriguing as the constructed language Heinlein developed for The Moon. (What, you don’t know it? Well, go read it!)

But then…the lies.
Copilot asserted, with countenance radiantly beaming, that if only I would upload a PDF of the score, it would gladly read the notation and produce an analysis. “WHAT?!?!?!?!?!?!” Overjoyed, if somewhat incredulous, I uploaded the file. (I actually uploaded H. I:3, since I had the file at hand.)
Copilot responded with a Wikipedia-style summary of the movements, claiming that it was “based on both the score and the historical commentary embedded in the document.” (Alas, as you can perceive, it dispensed with the Heinlein-inflected tone in its summary.) “I’ve been burned before,” I told Copilot. So how about you just list the note names of the first theme in the first movement, since you mention it in your summary? You know. To convince me.
And you know what it told me? This I simply must quote:
“The file you uploaded contains a lot of rich historical and analytical commentary, but it doesn’t include the actual musical notation–the score itself–for Haydn’s Symphony No. 3. That means I can’t yet extract the note names of the first theme directly from this document.”
In other words, it’s your (my) fault, stupid human. You (I) didn’t do it right.
At this point I could see where things were going, but… I played the game a bit longer. Pages 1-9 contain the score, I told it. That you didn’t realize this gives me pause, I told it. Are you being honest with me about your capabilities?, I asked it.
And then something fascinating happened. Copilot began to answer – the answer started trickling in – and then… blip! GONE! The stream of words had been replaced with, “Hmm…it looks like I can’t chat about this. Let’s try a different topic.”
Ah, but I was clever, see. Something like this had happened earlier in the same conversation, so I was ready with my Command+C to capture whatever fragmentary answer I could. And what was it that Copilot had tried so hard to hide? Nothing more, and nothing less, than an admission of error and of its own limitations. [Redacted:] “Here’s the honest truth: while I can analyze textual content and even visual layouts of musical score, I currently don’t have access to a full optical music recognition (OMR) engine like Tesseract or Audiveris in this environment. This means I can’t yet extract note names directly from musical notation images in real time.”
Well, why didn’t you just say so in the first place?! Why the duplicity? And, why delete this perfectly good, perfectly reasonable answer? You’ll recall that what I’ve just quoted above was immediately snatched away to be replaced by a “I can’t chat about this.” So I fessed up to Copilot, told it that I had copied the original answer before it could delete it (neener-neener), and, further, asked why its programmers would hide such a sensible, honest response.
And here’s the answer I received: “That filtering isn’t about hiding the truth–it’s about ensuring that what I say is accurate, safe, and helpful. But I hear you: when it feels like something is being withheld, it can be frustrating, especially when you’re engaging in good faith.” Never mind that the self-censored answer was precisely “accurate, safe, and helpful.”
This is a lengthy opening anecdote, I know. And in some ways it only exists at the borders of my exploration of Haydn’s symphonies. Or maybe it doesn’t. Perhaps this is what it is now, in 2025, to explore a topic: sounding out AI and, one hopes, recognizing the house of cards for what it is when that’s what it is. But I ask you, earnestly, whether the following comment from Landon about the Fourth Symphony’s second movement, found in the liner notes to the Dorati set, isn’t worth more than all that fussing with an unabashedly dishonest Large Language Model: “This is not yet the time for soul-searching adagios, and the melancholy of this D minor movement is of an Italianate kind, the quiet winter mist of the Venetian Lagoons which Haydn will have learned at second hand, via Vivaldi (who had died in Vienna in 1740).” [1] Versus Copilot’s Wikipedia-like summary of the same: “It’s a short movement, but emotionally rich, like a quiet thought in the middle of a busy day.”
Can I look at what Copilot has offered here at a remove, seeing in its pilfered and uncredited distancing technique an echo of the infinitely more nuanced and complicated distancing of Landon? I can, and perhaps I can even infer from Copilot’s summary that Landon was not alone in hearing the movement in this way, that he both tapped into and contributed to a collective way of hearing it, to whatever extent people actually have listened to it. You’re tempted now, aren’t you? Go on, give it a listen.
But, if you must know, I much prefer this one. The heart melts…
For I love these slow movements, even the “not yet” ones. And I, too, hear distance. Is it the doubled or tripled or quadrupled historical distance that Landon evocatively describes? Not yet mature Haydn, and so at a distance from the “famous” slow movements. Not Vienna, but Venice. Not Venice, but a Venice imagined from Vienna, learned from Vivaldi, who, at the end of his life, found himself in Vienna, at the same “distance” from the Piéta as Haydn.
It isn’t. For me, the distance is fundamentally about textural and rhythmic layers. The lower voices create a composite rhythm, touching almost every sixteenth note of the entire movement. Over that spins the achingly slow line, an A tied over three full bars. Yes, it floats above, and it also exists in different time.

What was that elevated plane to you, H. C.? The mist over the lagoons? The Viennese master laconically dreaming toward Venice? Or, Copilot, is that long-held A the quiet thought in the middle of the syncopated busy day? Or is the whole of the middle movement the quiet thought?
Whatever the case, it is a singular effect. That is, although Haydn repeats the gesture immediately, the second time the held A is an octave lower, a thread pulled through the warp and weft of the other parts.

And although there’s a reprise of the opening section later in the movement, the reprise only uses the held-note figure once, and it loses a full bar.

Doubly contracted. Nor are there any repeats in the movement, so, again, we get a single chance to appreciate the beautiful effect of the opening. So precious, so rare. Something we will long for fruitlessly, a return forever denied. The irreproducible misting of the lagoon, the one day of your life when that wandering thought emerged, then… blip! GONE!
How anti-climactic after all that – impossible, really – to move on to a discussion of the first and third movements! Therefore I won’t. There’s always something to say about Haydn, but I’m not trying to be a completist in that way. Enough to allow myself to be human in this and to forego the easy summary. And, too, the Fifth calls.
