What's the most important thing to do when writing to ensure that the story has the tone you want it to have?
Brandon Sanderson
Boy, I'm not sure if there's a one catch-all most important thing. The answer, unfortunately, to most writing questions is: practice a lot, and then show your work to people and get feedback, and then learn how to target it better. With tone, one thing I've noticed that is really tough to pull off is switching very frequently between something that's supposed to be humorous and something that's supposed to be serious. And this is not a bad instinct, because some of the great filmmakers and writers we know are able to do this. This is like a Joss Whedon hallmark, right? We're gonna go from witty comeback to sudden gravitas in the matter of, like, whiplash. So we're like, "Wow, I like movies like that, I like books like that. Terry Prachett can make me laugh and then make me cry in the space of a page. I want to learn to do that." But it is really easy to have your tone go completely off the wall when you're trying to do something like that. And whenever I fail on that thing, on tone, it's almost always because I'm trying to inject something funny into the middle of something with a lot of gravitas.
This actually happened-- "Funny" is maybe the wrong term for it, but in the last Wheel of Time book, a scene we cut. The beginning of the Wheel of Time book, to not give spoilers, start with a really dramatic fight scene where some people are struggling to survive under terrible situations, and they are getting picked off and dying, and things are burning. And I alternated that with a different scene I had written separately of several characters getting engaged. Which were both scenes I wanted in the book; but when I finally came to fold the stories together, these different threads, this one went opposite this one, and wow, it did not work. It was so bad. You would be reading these scenes about people dying, you'd be like, "I'm not interested in the people getting engaged." Even though it's something that maybe you've waited for the entire series to read because of the tone mismatch of where you're jumping back and forth. So that was one where we actually cut out the scene of the engagement, and just let the scene that was the more powerful scene stand on its own.
