I taught myself to play the guitar in the keys of C, A, G, E and D. For a long time, I never used a capo, but, since my voice is my main instrument, I slowly began to realize I needed to use a capo to get the correct pitch to make sure I'm singing and playing in the right key that's comfortable for my voice. I have been reading posts on capo use for this site as well. What are the most common keys a baritone sings in (when accompanying himself on guitar?)

I usually put the capo on the 1st, 2nd, 3rd and 4th frets when singing, and play in the key of C (C,F and G chord shapes.) When placing the capo at those frets, what keys am I playing in?

If I put the capo on the 1st, 2nd, 3rd and 4th frets and play G chord shapes (and so on in the 5 keys I play in), what keys will I be playing in?

Thanks for your help,
Scott
