I'm playing guitar in the orchestra for a musical at my high school and I was having trouble voicing a G2 chord. I feel like an open voicing would be overkill so I wanted to use a shape that is movable across the neck and doesn't require any open strings. To me this is an unusual chord but the score requires me to play these types of chords quite often. Any tips for finding an appropriate voicing?
Also, I guess what's also giving me trouble is the fact that I'm actually unsure of what the notes for this chord are. Is this the same as a Gsus2 where I omit the third and substitute it with a 2nd? or is it more like a G7 (dominant chord) where I keep the third and add a minor seventh ( in this case I would add a major 2nd in the same octave as the root)? My guess is that it's former but ultimately I'm unsure.
