A sonnet's what this is, that much is plain
There really isn't any need to stare
Its introduction's made in this quatrain
Two more will follow, then a rhyming pair

It is iambic, so it goes “dot dash”
Two syllables a foot, five feet a line
The rhythm takes you onward in a flash
The sense of structure's reinforced by rhyme

After the first octet, a change of mood
The sonnet's true intentions are revealed
Its themes are love and essence, nothing crude
Hard hearts begin to melt and ******* to yield

Then closure as it slowly slips away
A soft exit – a pyrrhic fall – spondee.
