So I am attempting to write a song, and I have gotten stuck on the solo. The main chords used in said song are C, D, G, and E. This is the key of C correct? That means that I could play the solo in an Am pentatonic style right? Any help would be great.

Sincerely,
A struggling teen trying to learn theory better

The key of G fits better, but then the E chord would be a minor chord.
G major (pentatonic if you like) or E minor (pentatonic) will work fine over that.

Thanks JB95, I've been trying out Em instead of E, and I couldn't decide. So G major/E minor would be with the Em?
