Three Women in a Small Town

[Exit]

As Exit points out, Coleridge's 'Rime' was in couplets. Actually, so was 'Christabel'. The meter, however, is quite different:
'it IS an ANcient MAriNER and he STOPpeth ONE of THREE
by thy HAND and EYE thou GREYbeard LOON now WHEREfore STOPPETH thou ME'
as I recall.
I'm not the world's best at scansion - the late Leanne was the nonpareil in that department - but you get the idea.
Not familiar with WW's longer rhyming works (The Prelude or Tintern Abbey don't rhyme, as I recall) or Blake's. A lot of Blake is quite terrible by present-day standards and is only read as a historical curiosity, much like Shakespeare's mundane sonnets, let's admit it.

Exactly! I don't think this has a consistent meter. But needs one. I think it should be 5, 3, 3, 4 (or 8 7). But that was just based on the "will" line that seemed to force an inexplicable rhyme. And as I said my suggestion might not be consistent with the rest of the poem. However, I do think a consistent syllable count and stress-awareness would benefit the poem. 

And how dare you say Blake is anything but a genius! If it weren't for Blake life would be unbearable. :*
