"Music is a form whose meaning depends upon its violation."

Jonah Lehrer analyzes "the neuroscience of music."

But there's something I don't understand about his whole explanation. It's all about how music sets up "expectations" and then violates them, or delays the satisfaction of them:

While music can often seem (at least to the outsider) like a labyrinth of intricate patterns – it’s art at its most mathematical – it turns out that the most important part of every song or symphony is when the patterns break down, when the sound becomes unpredictable. If the music is too obvious, it is annoyingly boring, like an alarm clock. (Numerous studies, after all, have demonstrated that dopamine neurons quickly adapt to predictable rewards. If we know what’s going to happen next, then we don’t get excited.) This is why composers introduce the tonic note in the beginning of the song and then studiously avoid it until the end. [I don't know of any music that fits that description! — JAC] The longer we are denied the pattern we expect, the greater the emotional release when the pattern returns, safe and sound. That is when we get the chills. . . .

The uncertainty makes the feeling – it is what triggers that surge of dopamine in the caudate, as we struggle to figure out what will happen next. And so our neurons search for the undulating order, trying to make sense of this flurry of pitches. We can predict some of the notes, but we can’t predict them all, and that is what keeps us listening, waiting expectantly for our reward, for the errant pattern to be completed.

Here's what I don't get: I've listened to the first movement of Beethoven's Fifth Symphony so many times that I know in advance what the whole thing is going to sound like, note for note. There isn't a single moment in the piece that I find genuinely surprising. I don't expect anything else from it other than exactly what it gives me. (Even if you're not a Beethoven fan like me, one so often hears the movement played that you could easily become well-acquainted with it without trying.) If enjoying music is all about challenging our expectations, shouldn't this movement fall flat for me? But I find it one of the most effective and emotional pieces of music in the world.

This video even gives you visual cues about what's going to happen in that movement before it happens (by Stephen Malinowski, who has over 100 of these). I don't find that this detracts from the musical experience at all:
