"It has been realized that in many languages there are principles of rhythmic organization which serve to keep a roughly even rhythm. This is not to say that we pronounce prose like poetry; rather, what is found is that there is a strong tendency to avoid sequences of accents which deviate too far from this simple rhythmic pattern. […] This general tendency is sometimes called eurhythmy."

Edit: QUO-ted and NO-ted SOLE-ly be-CAUSE eu-RHYTH-my is SUCH a WEIRD LOOK-ing WORD
