I just had half a discussion about why we read poetry and I am thinking at the same time about why I write poetry. I think during the Teenage Angst Years, I wrote for the same reasons a lot of kids write: to Express My Inner Turmoil. This is not a bad reason for writing, and if you can also make money off it (which some novelists and pop singers do manage to do), that’s even better.
Sometimes I write to experiment with sound, as I did when I wrote a dozen poems about Jack of the Beanstalk with tons of internal rhyme to get a bit more of a constant rhythm going, or when I wrote twice that many about flamenco, using staccato short lines to try to convey the percussion’s feeling.
Sometimes I write to tell stories, as I do when I unpack what I think is going on in a Japanese woodblock. Sometimes I write to take a story that already is out there—Jack of the B, Xena Warrior Princess, the Wright brothers—and go deeper into it, looking at it from a few sides.
But sometimes it seems just a matter of elevating experience, giving dignity to our joys and sorrows as Marge Piercy might say, through finding all the exactly right words to make Truth happen.
