One of the great tragedies of childhood was my inability to harness the forces of witchcraft. It wasn’t for lack of trying. You have no idea how many times I stared at my homework and wiggled my nose, hoping to cause math problems to magically solve themselves, how many times I urged the kitchen dishes to become spontaneously clean with a snap of my finger. For years I was convinced the problem had to do with sound effects, or more specifically a lack of them. On “Bewitched,” whenever someone cast a spell, it was invariably accompanied by the sound of a harp or a bell or both. My spells were devastatingly silent.
