One of the questions on my homework assignment asks me whether the meter on Annabel lee is iamb or anapest. It's described as both here: http://www.shmoop.com/annabel-lee/rhyme-form-meter.html
How though, can you tell what kind of meter is used? Who's to say that
It was ma/ny and ma/ny a year/ ago/
Isn't
It was/ man*y*/ and man/y a/ year a/go
I completely agree that the first sounds better, but is that the only way to determine the type(s) of meter used? Would I have to go through each possible meter of every line of a poem to figure out what was supposedly used?
