what makes this a good poem is not that it conforms to an arbitrary pattern
it's good because it says something
Right. I agree. To a degree.
See? And you thought you'd get an argument from me?
But the forms are also very useful to the craft. It's good for you. And you know a poem is more than what it says. The phrasing, the rhythms, the meter, the techniques used in the language, all are important parts of the craft. The forms are exercises of those skills.
One of the most important things about poetry to me is how it sounds, how the verbiage works. Sometimes it doesn't matter what the message is, what it "means." The music of it is more important.
And the forms are musical structures.

EDIT-
You edited your post as I was posting. You added something about music as I was writing about music.
What I was replying to was only what I quoted. that's all you had up there when I replied.
Jinx.
