I took a few guitar lessons form a music shop when I first got my acoustic in the early nineties.
Keys are my main instrument.
I don't know much on guitar outside of how some subtle minor key shadings can swing a songs mood.
Especially with goth rock. But then there is overkill.
I used to tune my electric so loosely that it was like spaghetti, pretending I was Bauhaus or some death metal band.
I was told to bring my acoustic for lessons. And my teacher, who was a big folk and prog freak, taught me "Dust In The Wind". I believe the chords were C, G, A Minor and D.
Although there may be different variations of it, I never got a Kansas song book.
I learn guitar songs mostly ny ear.
Everyone recognizes the song without me having to say it too.
I did that with "Roundabout", plus some Pink Floyd songs.
My only other exception to not learning by ear was "Hotel California".
The chords are actually pretty basic to that song, but it's that finger picking rythmn that throws me.
Tab can be hard for me to understand too because some songs are tuned differently or at a different pitch.
I am for the most part tone deaf.
But I can often nail songs by ear.
And of course, I learned those metal songs like "Shout At The Devil", to those ones that every kid of that era learned, "Iron Man" and "Smoke On The Water".

I plan on taking a music course online.
I would like to kick out a cd, but would like some practical, more hands on experiemce.
But reminincing through my kiddie bag has been fun.
