Found this terrific piece on cadence and beats at the sentence level on Writers in the Storm. I especially like the rhetorical devices guest blogger Margie Lawson provides. As a rhetorician, I’ve encountered many of these in my research, and I’ve used many, even if only intuitively, in my writing.
I’ve written about some of these in my Novel First Lines series, and in my post on the effects of commas on cadence. Meter and rhythm are powerful lures in the first lines of a book or story. For a wonderful discussion of rhythm and cadence as persuasive devices, check out Martha Kolln’s textbook (find used copies), Rhetorical Grammar.
See if you use any already—and what you can learn to use.
