5. A statement to introduce voice.
“Lolita, light of my life, fire of my loins.” Vladimir Nabokov’s celebrated opening is not designed to convey characterization or plot, though both are present, so much as to introduce his distinctive style. Anthony Burgess opens A Clockwork Orange (“What’s it going to be then, eh?”) without any plot, characterization or setting at all—merely the ominous voice that will accompany the reader through the text. Stories that begin with a highly unusual voice often withhold other craft elements for a few sentences—a reasonable choice, as the reader may need to adjust to a new form of language before being able to absorb much in the way of content.
