Form defines so much. Haiku. When language is constrained, trained like bonsai, we have to find the essense. Oration. What sounds right? Find one more point to make a parallel three. Pick your points so they alliterate. What does and doesn’t rhyme will actually define what you argue; even what you think. Painting. The thing as a whole is so important, but also the details. Pacing is hard to control. You can hide things in detail, but then they may be missed entirely. So much power is in the viewer. That changes not just how you say things, but what you do say. When I write a script, it matters what can be done on a stage, by the actual actors I expect, in the time I can hold the audience’s attention, in the mood they’re likely to be in.
