Subtitles, Drama and the Rule of Three
Titles are without a doubt one of the most vital elements for a successful book. But subtitles, while clearly "sub," still matter a lot.
One way (not the only way) to construct an effective subtitle is by using the Rule of Three. Offering a list with three items gives a rising sense of movement, climax and direction. Consider these subtitles:
The subtitle for Unbroken clearly shows a progression. The subtitle for The Blood Sugar Solution doesn't move chronologically but rather develops in terms of emotional benefit. For God Behaving Badly the subtitle makes a cumulative impact.
Titles or subtitles with two items can be helpful for purposes of comparison and contrast. But they tend to be (though aren't always) less effective because the items balance each other. On the positive side this gives a sense of stability, but negatively it can be less interesting because there is no sense of change. Consider two titles with paired items:
When using the Rule of Three in a subtitle, the longest item should almost always go last. Why? Rhythm overrides significance. Try reading (especially aloud) any of the following subtitles with the last item in the first or second place. Those options are always flatter. They lose their punch.
It's not impossible to have a title with three items in a list. Guns, Germs & Steel was very successful. But as important as the Rule of Three can be, it can be trumped (especially for a title) by the Rule of Memorability. If people can't remember the title of your book, that's trouble. And a sequence of three can be elusive.
On the other hand, while the Rule of Three isn't the only way to achieve an effective subtitle, it can be the road to impact, grabbing attention and a successful publishing venture.
