Wow. Great info. Wish I'd got in earlier but it's ALL here. Good work Mark, Gary and Swan.

Perhaps I can add that some "predictable chord patterns" are named after specific songs. "Blue Moon" might indicate the 1 6- 2- 5 pattern so commonly used in early rock ballads. "Rhythm" changes are named for "I got rhythm" and might (there are variations) go 1 1#dim 2-7 57 (damn, this looks awkward when i type it..works great for scribbling lightning chord charts though, or just calling the changes to a band mate while playing.

1 6 2 5 is often called "circle of fifths" (or just "circle")
