Some writing flows with a euphonous cadence. Because most people can recognize cadence, and whether a piece is of good cadence, likely, through skillful editing, they can create it. And methods of varying diction to help them do this -- they exist. So my question is this: Can you give these methods with examples?
I want to clarify, that I am asking for different methods of saying the same thing in different words. This question, as far as I know, has never been adequately answered here.
Read what you have written aloud and feel if it can be spoken easily and fluently without effort. Then it has good cadence.
The best solution to your problem is simple. What you do is write in possessive voice. Writing in possessive voice is your guide to cadence, as you call it, but I've never heard of it, this cadence as you call it, but there you have it. The guardrail is possessive voice and control, even with longer and sloppy sentences. This will keep things under control, and at all times during the ride along the information highway as I call it. I don't believe in cadence. I believe in possessive voice. Possessive voice is my cadence.
An author will adapt ways of speaking that normally aren't reachable, normally not by most, and the author will think unnatually, unlike most. This is a skill that is learned through practice. It doesn't have anything to do with editing, but everything to do with how one is thinking and managing, which is all learned attributes learnt through trial and error and patience and practice.
What it does is grows on you, as the creator of your art and all aspects of your creations. It's hard to explain, because it's something artists do naturally from being exposed to language and trance and art for very long periods of time and intensities. I assure you it has nothing or little to do with the likes of editing, or what editing does for a piece of fiction.
