As I've been rereading my Steampunk from NaNo, I find myself thinking a lot about voice. Not my characters' voices, but mine.
I believe one of the ways voice is showcased is in length - length of sentences, phrases, paragraphs and chapters.
My sentences vary in length, but I do use a lot of short, tight sentences, and more than my share of sentence fragments. I like the effect. I know some people believe fragments should never be used. It's one of those grey areas. I think I know the rules well enough to break them for effect & emphasis. Will readers agree? Don't know yet. :)
My paragraphs tend to be short as well. Obviously they vary in length as needed, but I do include a lot of one or two sentence paragraphs.
This tendency of mine extends to chapters as well. Again, there is a fair amount of variety, but I have more short chapters than long.
I believe this is part of my voice as an author. When I look at some of my favourite reads, I find I enjoy variety. Some of my faves lean towards long sentences, paragraphs and chapters, while others run towards short with more fragments. As I read widely, I'm not terribly surprised at the variety of styles I've found!
When you look at your writing, do you find you have a preference for long or short? Do you think this affects your voice?
