Hello!
I am returning to guitar after a long time off. I was mediocre at best, I could play some songs, knew chords and could use TAB, but I have no idea what I was actually doing. I had zero working knowledge of the fretboard and couldn't tell you what key I was playing in.
I want to give this another go, this time with Bluegrass instead of rock and blues. It seems the lessons on here are rather advanced and not geared for my limited ability. Is there some beginnerish content here?
I see your point.
If you can afford it and bluegrass is what you want, you could test artistworks.com
Bryan Sutton has Basic guitar lessons, intermediate and advanced.
Or maybe banjobenclark.com
Paul Davids on youtube has really good videoes on music theory and lots of other stuff. Explained in a very understandable way.
I can also recommend guitar books by Barrett Tagliarino.
