schiller's bell

"We speak of learning poems by heart, not by mind, for once we have fully absorbed them they are much like our heartbeat, a rhythm we feel within. And when we unscroll “Die Glocke” from within, rather than reading it from the page, we experience it in palpable physical terms. We become the bell founder and bark his brisk orders, then turn away to muse on their ramifications, only to be wrenched back as the bronze begins to bubble. Schiller reinforces this movement, which darts and flits like living thought, by sharp changes in meter. The reflective passages are iambic, the stress landing on the even syllables in a steady reassuring rhythm. But as soon as the bell founder speaks to his apprentices, he shifts to trochaic meter so as to stress his orders--cook the copper, check the mixture, etc."
