This is a practice I’ve been doing almost since the beginning. Bestowing every chapter in a written work with its own title helps to give it some context, methinks. The few words that comprise it can be used to comment on the general vibe of the chapter or give supplementary information, in a way that doesn’t interrupt the flow of the narrative.
My chapters frequently go through several working titles before they settle on a definitive appellation. The chapter I’m editing now sees our heroes visit the top-secret lair of a powerful warlock on the island of ₪KLAVERIOS, who after several rewrites has evolved into someone vaguely like a hybrid of Morpheus (of The Matrix) and the character Q of James Bond fame, with maybe just a smattering of Glinda the Good Witch thrown in. This exhibition-heavy whopper of a chapter’s original working title was:
…AND ALL I GOT WAS THIS LOUSY T-SHIRT
After fully digesting this chapter’s innards and melding my consciousness with its innate atman throughout the editing process, the old title found itself abandoned like an outgrown shell. Replaced with the (somewhat) more cozy WHO IS THE TRAINER? It’s possible the original title might be claimed by another chapter down the road; it would probably fit the next chapter after this one like a glove.
