Rhythm and rhyme are very woven into our concept of mystery and power, I think.
Just how I feel about it. I do notice that it's easier to build energy when the spell actually rhymes.
Or just power in general. Just think about how they used to(don't know if they still do) rally up morale/spirit among the armies. They would give them chants or songs of sorts to inspire them to fight their hardest in battle. Back in the day, it wasn't uncommon for armies to have drummers or drummer boys to accompany the marching army as they chanted and sang and such.
I know that the Vikings used to have rhythmic drumming for their oars when they were sailing. Then again, if I'm not mistaken, the Vikings also used drums when going into war/battle.
Pirates used to sing sea shanties. Whether it was for amusement, or attempting to rally the aforementionned spirit..I honestly do not know.
xp Also, back in the times of the Ancient Greeks and Romans, folklore/myths were actually sung and not told as stories.
So, songs and rhythmic chants and such have been around with us for quite awhile.
When you look a Buddhism, there are chants that one can repeat while meditating. These chants are the way they are to help you to focus on one thing; one rhythm, one sentence, one meaning while meditating. Now, when you look at spellwork, I'd say that the rhyming and rhythm in that case might have a similar function. It might just make it easier to focus upon.
Besides, ever remember the teachers trying to make you memorize things in school? They'd almost always put it together as a rhyme? Why? Because it's usually easier to remember/to focus on.
Well, at least that's what I think.
