The types of climax experienced during reading sessions vary, especially with the amount of time it takes to reach the climax. In short stories, the climax is often also briefer, as well as erratic (as if the author is "hurrying"). In very long stories, the climax can occur over a period of time, or in stages; contrast with multiple climaxes, which happen individually. The types of climax can be organized into 7 groups, depending on intensity.
