Changing POV is not head-hopping. The term ‘head-hopping’ means that a POV is changed so much in a scene that the reader is being forced to hop around so much they’re dizzy with it. And because of that they’re confused as to who is doing what, which is something you never want to have in your story.
So, how do you avoid that if you want to change POV in a scene?
First, make your character’s voice distinctive enough so that when you change POV it’s a seamless transition. This means that when you’re in a particular character’s POV you’re using a very distinctive voice for them, and I’m not just talking about the way they speak in dialogue. Each character should have a distinctive way of thinking and acting in addition to speaking. And you don’t need to make the differences super-obvious or extremely-different unless your story calls for that.
Two, understand what you want to do in a particular scene in terms of action and what information you want to reveal about the plot and characters. Sometimes it may be best to stay in one character’s POV because if you go into another character’s POV you’ll reveal a plot detail before you need to. I did this in the very first scene of my novel-in-progress because if I had gone into my other character’s POV I would have spoiled the key surprise plot element, so to speak.
Three, think of the development of the scene in a cinematic way. When you watch a movie for example, most of the time there are cuts within a scene to show the reactions of other characters to what’s happening. So if you feel that need to cut to another character in your scene, then you’re looking to change POV.
Now, I know there are what I call POV-purists who believe in one POV per scene and will only change POV with a line or scene break clearly showing that on the page. And that’s perfectly fine as I’ve read plenty of books written like that I enjoyed. But please don’t feel like you have to do that. Maybe the thought of changing POV in a scene is daunting or you’re not sure of how or when to do it. Don’t be afraid to give a try and in the meantime, study other writers and see how they do things.
Most of all, don’t feel like there is a set of rules governing POV that you can’t break unless you want to go to jail. Trust me, you will not be jailed for changing POV in a scene. If you do it and someone says you’re head-hopping, then you’ll need to look at your work more closely to make sure your changes in POV are seamless. But trust me, it can be done if you want to do it.
