Rhetoric, long-listening

My teacher, Tony Brandt, talks a little bit about 'rhetorical reinforcement;' that is, the alignment of phrasal, harmonic, rhythmic effects to articulate a single rhetoric. Otherwise, the discussion of rhetoric was entirely missing from my music education. This strikes me as bizarre, since it is the feature that most contributes to music making 'sense.'

It certainly trumps harmonic language. I've been noticing an illusion lately. Maybe some of you can corroborate. I am hearing more and more serial music as tonal. I'm using the term loosely; I suppose I mean that it sounds harmonically conceived. I hear the harmony align with rhetoric of a phrase. I hear the harmony working as harmony. This effect is particularly strong at the ends of phrases, when the final chord can really linger in my ear -- it often sounds like a perfect chord for closure, and I cannot believe it was chosen out of serial necessity. I think, surely Webern cheated here.

[This is what I think is happening. First, I've been working on my listening. I'm too focused on details, and teasing out intervals, and I miss the long phrase. So I've been practicing long-listening -- don't get hung up on details, be more patient. Listen for the rhetoric. And as I let the rhetoric have more influence over what I'm hearing, it is casting harmonic detail in its own shape. If the rhetoric of a phrase creates convincing closure, the harmony I hear is one of convincing closure.]

And it certainly trumps motivic unity. How many pieces have you heard that were supposedly motivically watertight but were impossible to follow? And then compare that type of piece with these:

Brad got me hooked on Boulez, Notations for Orchestra. I don't know enough about how they're made; maybe they're working motivically too, but I can't hear them that way yet. For now they are rhetoric alone, and it is absolutely enough.

And our resident quartet, the Jasper, played Ligeti's Metamorphosis Nocturnes last week. There's a piece where the motivic consistency has a fantastic effect -- but it is reinforced by an absolutely direct and clear rhetoric.

Who is talking about this?
