I like some of the Stones tunes, and have for YEARS!! “Start Me up” and a couple of others. I didn’t know how they played it, but figured it was mostly Bar Chords, so I went online and saw “Open G” tuning seemed to be the “way” it’s done.

So I tuned up, and started messing with “Open G” tuning. Here are the first few moments after a couple of instruction videos on how to get there.
