This third section continues the forward trajectory from the first two, having become slightly less tense and perhaps more thoughtful and introspective. Dare I say that? I hate overly describing my music. It either dictates how people feel about it, or it turns them against it for its failure to do so. Best to let it speak for itself, in general (there is the occasional exception). Let people form their own opinions about what's "being said," etc. Uh oh, I'm sensing a tangent ....
Again continuing on with the anxiety motif. I stumbled upon this chair behind a tall fence. It was quite out of place. It made me uneasy. Seemed to fit.
