SECOND EDIT: Sermon on the Destruction of Icons

[tectak]

I think I see what you mean. To my hearing, or the way I was sounding out the line, "aisles" was two syllables (eye - awls), the first long and the second short. Is that what you're referring to, the amount of syllables in "aisles"?

Yes and no. You can, and I do, fool yourself into meter. Ay-uls is a stretch by any measure in the same way as regional accent may say dow-un for down...but it is just plain wrong contextually. Please don't get me wrong. Regional accents are just fine but you must be either a) consistent or b) insistent. To be insistent you write the word in colloquial fashion. That is:

Dow-un ay-uls built fo-ah yurnin' sheep.

...but no, that is not what you are aiming for.
Best,
