So this is a thing I've been putting together for a while. I realized a few months back that you can Capo the banjo at various frets, and all the chord shapes correlate to different chords in different keys. So without a Capo, we are in the key of G, and the C shape plays the 4th of G scale (C), and the D shape plays the 5th (D). You can take this and move the capo to any different fret to play varios parts of of all the different Major scales, so if I'm told I'm in a key, I can switch to that scale and just sort of riff within the shapes. It's very basic, and I am no master of music theory, but this has been a great tool to quickly play on top of really any piece (once I get the key!).
