We were asked a good question recently from a new mandolin player. "Do our basic key charts also apply for mandolin." The answer is yes, the basic keys apply to all instruments. The chord shapes will be different for each instrument, guitar, mandolin, piano, etc. but the keys and their components are the same.
So lets say you are playing in the key of E, and E is the 1 chord, then the 4 and 5 chords will be A and B across all instruments, including all their variations.
Thanks for the question, keep them coming, I love to hear everyone's responses.
