I really liked ‘Sailin’ ‘ when it came out. Joni Mitchell is an interesting guitar mentor. I had a girlfriend in the 70s who studied Mitchell’s guitar style... she used atypical tunings to come up with all sort of unique effects... really opened my eyes to how ‘different’ Mitchell was.
Yes she did, I guess alot did, even Neil Young used to tune the top two strings the same on some songs. These folks are in another league when it comes to that stuff.
