But I can give you a couple of tools to try. Or, as Inigo put it so well, "Let me 'splain. No, there ees too much. Let me sum up":
- Have your computer read your scene to you. I find that listening to my story reveals a great deal, especially where the pacing is too laborious or too frenetic.
- If you don't have a good voice program on your computer, read it out loud and record it. Or have a friend do so. Then listen to it.
- Keep an eye out for scenes that lose your interest as the writer. If you're in the middle of a scene and suddenly realize you haven't a clue why you're there, or what you're hoping that scene does, take a look at pacing. It could be you've been, to follow Vicki's comparison, yelling or whispering too long. Too much of either can lose readers.
- Finally, pull out one of your own favorite movies. Watch it once, all the way through, so you can remember why you love it. Then watch it again and evaluate the pacing. Notice what they use to speed up the pace and to slow it down. See what you can learn from it.
