That rhythm should not be unvaried. Some writers tend to fall into a rut—like the one mentioned in chapter 1, whose scenes were all about five minutes long. And in some cases, the steady rhythm of similarly sized scenes or chapters can reinforce a story’s steady forward momentum. But if the scene or chapter length remains steady while the tension of the story varies considerably, you are passing up the chance to reinforce the tension your story depends on. You are failing to use one of the simplest of storytelling tools.
