Mr.Wagner never believed in hell, I don't much either, oh well... to his amazed surprise, after he died, his eternity's being spent hungry and fried, cast down upon a burning plain, ravenously hungry, skin boiling pain, beside him a pile of mouldering dead, he could endure the hunger, remain unfed, but as he screamed his hatred to Gawd, he left no fucking bone ungnawed.
they certainly are fun but there are key components to poetry usually lacking. mostly meter.
This is a watered down explanation and there are always exceptions to rules and exceptions to exceptions but each individual line must maintain a consitant beat. do-dah-do-dah-do-dah-do-dah rather than dah dah do do do do dah do. Every word in its annunciation has a stressed syllable. Poetry demands that this stressed syllable land on the same part of the beat. If the first syllable is stressed and the second is not then you must maintain that pattern of stressed unstressed throughout the verse. Using the first line of this poem as an example. MIS-ter WAG-ner NEV-er be-LIEVE in HELL. The stressed syllable switches halfway through. A simple fix would be Mr. Wagner Ner' believed in Hell. You could also substitute believe for a synonym that has a stressed first syllable. Also the number of beats if odd must remain odd and if even must remain even. The first line has 10 syllables while the second has 7. this means that one line you end on an upbeat and the other you end on a downbeat.
These two rules are usually viewed as the most important, even more important that rhyming.
