Structured free writes can force interesting imagery. Create strict parameters, choose a subject and let go. I like playing with the form of Etheree - a poem that is ten lines long. The first line has one syllable, the second line has two syllables, and so on. There are no rules as to rhyme or meter. I like to write it as fast as possible, still keeping track and adjusting for correct syllable count.
For this Etheree poem, I closed my eyes, opened the thesaurus and pointed to the word "jazz".
don't work here
jazz is fresh juice
electric voice writhes
clarinets wail, wriggle
keening saxophones give wings
to embedded joys and sorrows
Wrested from their cells, their voices soar
tripping the clouds, diving into our mouths
Springboard du Jour: Try an Etheree about stormy weather.
