i'm not here to burst any bubbles, and i know this is way off topic anyway, but iambic pentameter is the simplest, most common rhythmic form in english and the germanic languages. i'm not sure, but something like 75% of conversational speech is in partial iambic meter, and pentameter falls right into place. the sentences don't have to have 5 iambs but the breaks in diction follow the 10 syllable pattern. now, if you want to get INTERESTING, try some amphimaceric septameter. (that's 7 amphimacers, each amphimacer reading long-short-long. this is essentially impossible but it can be done with a few pyrrhics and trochees thrown in. i think dylan thomas went off on this once or twice. speaking of going off....)
