"A little side point, human beings are not the only creatures that express themselves. Off the top of my head animals that sing songs: dogs, birds (of course), whales/dolphins. I'm sure their are many more. Music is in the air, as is poetry. I read a book that said something of how poetry exists outside the page because poetry has it's roots in oral tradition and really poetry is the art of imitating speech. Whereas prose cannot exist outside the page. It has no connection to our world."
This is interesting. The beat in Poetry not in prose mimics that of a heart or a pulse. It even flows like how we inhale and exhale. Maybe that's the reason why poetry stirs emotions more and is more effective.
