I think we pretty much agree, skeptic_ev.
And that’s a fine observation you make about a poem’s two authors.
The difference between Poe and Frost is that Frost is willing to sacrifice the form to the poem, while Poe sacrifices the poem to the form.
For instance, in “Stopping By Woods on a Snowy Evening” (a poem on which my opinion has changed completely in the last 6 months as my appreciation of Frost’s work in general has risen), Frost’s narrator is conversational, his language simple and direct; yet it manages to convey those things you mention with a power which is not only able to make us to see the scene unfolding in our minds, but to allow us to become the narrator if we choose to give ourselves over to the poem.
I said the language was simple, and it is. But the poem is not simple; neither in technique nor effect.
The rhyme scheme itself seems deceptively simple: aaba. Yet when looking more closely it turns out to actually be: aaba // bbcb // ccdc // dddd. And that last stanza’s construction is what finally lifts the poem into greatness – the repetition in the last two lines turns a lovely bit of pastoral poetry into a metaphorical and metaphysical window on the infinite and unknowable blank beyond.*
I say “finally lifts” because the process begins in the first stanza with the mellow ‘oh’ sound of its rhymes in tune with the narrator’s conversational tone. And it’s in the first stanza that the higher pitched “here” appears.
In the second stanza, the “eer” sound’s resemblance to a squeal builds tension as its rhyme works against the narrator’s laconic tone. And, again, another sound appears, the harsher, almost discordant “ache” sound which becomes the third stanza’s end-rhyme, where, against the speaker’s same level tone, it inserts the emotional sense of the verb “ache” through the use of its sound.
*So, in a sense, Frost is right when he says it’s not about death – it can be read as being about what’s beyond death, or about questioning if there’s anything beyond death … in which case, the second " And miles to go before I sleep" is about only having this life; therefore its responsibilities and joys etc are hugely pressing because they are all there is.
