How am I finding the rules? An example.

I'm finding many ways to create new rules.  Some come directly from listening to songs - others come from reading theory books, and others come from looking at jazz guide books.  Below is an example photo where reharmonisation "rules" have already been clearly lain out.  I simply simplified the rules and added them into the ruleset list.

By reading books like this, I'm able to find rules that are proven to 'work' in certain contexts.  Whether they work in the smooth-jazz context remains to be seen.  However, due to the wide variety of rules that exist, and the different types of chord sequences that I'm working with, some of these may work in specific contexts.  That's the fun of the project - trying things out at the piano and seeing what works and what doesn't work!
