That’s interesting. I think a problem I have been having is deciding how to end a chapter, how many scenes in a chapter, whether or not to mix POVs in a chapter, etc.
But lately, I’ve abandoned thinking about chapters for the moment. I’m just focusing on scenes in my first draft. That way I just get the story out, not worrying about everything I just mentioned.
Since I don’t have to worry about how long a chapter should be, I can write as many scenes as I want, figuring I’ll cut out many of them in future drafts. Before, I was trying to be economical with my scenes so chapters wouldn’t be so big. And I found that I wasn’t able to explore character as much. But now that I’m writing as many scenes as I want, I’m getting to know my characters more. And even if certain scenes don’t make the cut, I would have made the characters more richer. Also, since there are multiple arcs and POVs going on, I can figure out how to order these later. It has really saved me a lot of headaches. And the writing is flowing a lot more.
I did read once that chapters that are made of multiple scenes are sometimes arbitrary division points that helps organized the final form of a submitted manuscript. Now I see it as secondary to plot. They can be a way to tighten up future drafts, add suspense, etc. Not something someone to worry about in the first draft.
But now that you’ve mentioned JK Rowling actually does short chapters that are essentially single scenes, that also gives the possibility of not even having to groups the scenes in to chapters. I know short chapters are pretty common in pot-boilers, so there’s that as well.
