One problem some of us have during NaNoWriMo is difficulty pacing our stories. The beginning goes on for 40000 words, or we reach the final battle around word 10000. If our goal is a complete 50000 word novel, that doesn’t work. (We may be OK with writing 50000 words of a longer novel, or completing a short story, however.)
Knowing about the Three Act structure will help you pace your story. The first act is where you set-up your story. In the second act you develop it, and in the third you conclude it. If you skimp on any of the acts, your story will feel unbalanced and weird.
Plotters will deal with the structure in the outlining phase. Pantsers may be keeping it in mind as they write, or using the structure to sort out the mess of randomly written scenes they have produced. In either case, at some point you need to think about structure.
The first act is the first 12500 words of a 50000 word novel, or the first 1/4 of a longer novel. James Scott Bell, in his book Super Structure: The Key to Unleashing The Power of Story, gives us the following ‘signposts’ that should happen in the first act:
The Disturbance (to the Lead character’s ordinary world)
The Care Package (to show that the Lead cares about someone)
The Argument Against Transformation (Because your Lead is likely to resist the changes coming to his life.)
Trouble Brewing (Hint of the major story conflict to come)
Doorway of No Return #1 (Major change, Lead is now committed to the confrontation/conflict of Act 2)
The Lead is now committed to leaving his Ordinary World for the world of the story’s conflict/challenge. In a detective novel, this change may be in taking the case. In The Hunger Games, it’s when Katniss volunteers to take her sister’s place as tribute. In Act Two, the Lead’s life has changed in a big way.
Act Two is longer than Act One— 25000 words in a 50000 word story. About 1/2 of the novel’s total acreage. Act Two can drag if you let it. Here are the signposts that James Scott Bell gives us for Act Two:
A Kick in the Shins (Lead must face an obstacle— trouble related to overall story)
The Mirror Moment (Midpoint— Lead is reflective, realizes he must change or die)
Pet the Dog (Lead character shows compassion to animal or human, in spite of danger)
Doorway of No Return #2 (Lead is now committed to Final Confrontation)
The Lead is now committed to the Final Confrontation that the story has been pointing to. No chance to back out. This final act is the climax of the story, the pay-off that the previous acts have been pointing to. This act is about 1/4 of the novel, or the last 12500 words of a 50000 word novel. The Final Battle should take care of the major conflict of the story, and other loose ends must be wrapped up as well, so the Reader feels the story is done. The signposts:
Mounting Forces (The Lead’s Opposition is closing in)
Lights Out (The darkest point: all seems lost, Lead can’t win)
The Q Factor (Lead receives what he needs to win: encouragement, a weapon, knowledge)
Final Battle (Climax of the story; this battle will solve the story problem, kill or defeat villain)
Transformation (After the battle, Lead has been changed— show this)
Plotters will use the Three Act structure and the signposts before the writing of the story begins. You can use them as the framework of your outline. And, as you write, you can revise elements of that outline to make it more reflective of what you have in fact actually written.
Pantsers aren’t going to work all these things out in advance. They MAY use the signposts and the Three-Act structure to help them set the pace, and to work out what they should write next. OR, they may ignore much of the structure until the second draft stage. Yes, pantsers sometimes outline AFTER they’ve written a first draft, as a way to organize a batch of randomly written scenes into parts of a structured novel.
