Chapter titles are rarer than they once were. Today, chapter titles rarely go beyond listing the point of view in the coming chapter. Instead, chapters are simply numbered. When I started to write, I had the vague impression that numbered chapters were a sign of seriousness — of being more literary. Yet many of my favorite childhood novels used titles, and, halfway through my first novel, I added them on an impulse. It was only as I went on that I realized that there were several solid reasons for chapter titles.
The first reason is the simplest: on the whole, English-speaking culture is not numerically literate. Or, to put it another way, most of us do not remember numbers as well as words. You might be a person who remembers where they left off reading, or a reviewer citing a chapter, but, either way, you are like to recall a title more easily than a number. Titles, I believe, are a more efficient way of identifying a chapter than numbers.
More importantly, a well-chosen title can serve as an additional hook. Just as the opening sentences of a novel lure readers into the book, so a chapter title can lure readers into continuing onwards in the book. The only difference is that a title has fewer words to develop the hook — usually no more than half a dozen words. Usually, a title usually needs to be less subtle than a conventional hook. At the same time, it should not give too much away. Yet, within these restrictions, you can still hope to catch readers’ interest. Offer them “The Unexpected Guest,” and with any luck readers will stay around to learn who — or what — puts in an appearance. Similarly, “Blame and Betrayals” promises conflict, while “The Salmon Road” might lure readers onware for n explanation of the unusual phrase. More elaborately, if you can trust most of your readers to know their Chaucer, “The Craft So Long to Learn” suggests that somebody in the chapter learns something important to them. Used as a hook, a title can encourage readers to continue for just one more chapter — and maybe just one more after that.
Titles can also indicate themes. For example, when I retrofitted titles to my own work, I noticed that many titles referred to the relationships between families. It was only after seeing a table of contents that I made this observation — and after I did, it helped me to unify my writing by more specific references to families. Without seeing the titles in a table of contents, I might never have realized what I was doing, or had any control over it.
Other, more astute writers, can choose titles for themes deliberately. For instance, a story set in the early 1960s might borrow quotes from Bob Dylan to emphasize the setting. The Canadian fantasist Dave Duncan (who deserves to be much better known) once used lines from the old folk song “Sir John Peel” and named his characters after dogs in the song to emphasis, obviously but powerfully that the story was about a hunt, although of people rather than game.
However, perhaps the greatest advantage of titles is for the writer rather than the readers. In a one hundred thousand word novel, writers get all sorts of opportunities to practice different aspects of their craft. Yet if you number your chapters, a notable exception is the title — that you only do once. Perhaps that is one reason why so many writers agonize over titles. I myself generated at least three dozen titles over a year, and the final candidate did not even originate with me.
By contrast, after generating some thirty chapter titles, the next time I came to choose a title was much easier. I produced three titles in an hour, and in another half hour had my title. The next time, I was just as quick. I can only conclude that finding a title, like most aspects of writing, becomes easier with practice. Chapter titles, I conclude, on warmups for the main event.
Numbering titles do give you one less thing to worry about as you write. Yet when I stop to consider, titles are more useful for readers, and can help with thematic structures in general. I once thought that choosing numbered or titled chapters was mostly a matter of whim, but, having experimented, I am never going to willingly do without titles ever again.
