I'm trying to learn double stops and where they are without needing to think. I came up with this chart, can you guys tell me if there are errors or what you think of it? B and G string double stops, with high e,D,A,E 1234567 notes for filler. The BG strings are color coordinated per stop. I hope there aren't any errors because I've been learning this way for a few days. My tele goes to fret 21, so that's where I cut off the notes.
