The tuning on a mandolin is GDAE I believe. Despite this though, I see sparse mention on any mandolin chord charts of playing the Em chordas 0220 (from G-E). Yet these are all Em notes.
I know that G isn't the root note, so technically it'd be Em/G, but I do see Em chords played as 4223 which is Em/B
So if Em/B can be subtituted for Em, can I not do the same with Em/G? Is this not cheating?
