A sonnet is 14 lines of verse, usually grouped into four stanzas of 4-4-3-3 lines. Sonnets used to be written in metered verse, but many modern poets forget about the meter, or at least don’t use it consistently. Sonnets also tended to be written using any number of established rhyming schemes but that, too, is no longer a formal requirement.
A chiasmus is a reversal: Laid back, with my mind on my money and my money on my mind (from Snoop Dog).
My Body and I Face Our Future
My body, my blight, cataracts darken my sight
My body, my shame, with bunions I’m lame
My body, my bane, another sprung vein
My body, my pest, gravity lowers my chest
My body, my plight, and now cellulite
My body, my trap, a tree with no sap
My body, my curse, it’s going to get worse
My body, my shell, we’re going to hell
but my body, my all, we’ve answered the call
My body, my light, the end’s within sight
My body, my guide, I’m terrified
But my body, my source, I’ll stay the course
My friend, my body, we’ll dance to the end
Oh, body, dear, I beg of thee…..forgive me
