Sorry if this has been asked before, but I'm very intrigued by Plane-Talk. Ever since I first came to this site as a beginner (a little more than a year ago lol) I was intrigued by it but I was a bit hesistant on buying because it wasn't for beginners and I knew no theory.
But now I have learned some basic theory and I intrigue has come back

. Especially now because I really want improv. to be a big part of my playing style, so my question is what theory do you need to know so you can get through plane-talk? And why isn't it for beginners?
Thanks!
