I play a lot of folk and i recently started using a slide when i jam with people, I was wondering what are some open tunings for me to play in while other people are in standard (usually with a capo on the second fret) that match up and sound decent
open g is a very common tuning for that stuff
even with the other guitar in standard?
It wont matter. Any open tuning or any other tuning for that matter will work if you know your theory.
