These poems are called ballads. Some songs are actually based on ballads or ARE ballads because of the perfect rhythm that ballads provide. The core structure for a ballad is a quatrain, written in either abcb or abab rhyme schemes. The first and third lines are iambic tetrameter, with four beats per line; the second and fourth lines are in trimeter, with three beats per line. The second ingredient is the story you want to tell.
I hope this helps! Give me a rating to let me know how I'm doing.
