Try this for starters. Read a scene in rhymed couplets to someone you know, and ask them if it sounded natural. Not easy, is it? Great rhyme masters, from Alexander Pope to Richard Wilbur, require their readers to use these couplets on stage or page, and this is no small task. It asks from the performer something like singing. The regularity of the rhyme scheme, its dominance, can be treacherous. Peter Hall maintained that a script of Shakespeare’s can be read like music, but iambic pentameter is too strong and unbalanced to accept this kind of strictness all the time. Rhymed (sometimes called heroic) couplets need, indeed require, a balancing act. The listener knows instinctively when the rhymes are over-sung. I am saying there has to be a large and flexible middle to the actor’s method. This middle might be defined as the place that is returned to.
