So, I wrote what I feel is a very catchy, 2-chord section of a song. It could be either a verse or a chorus, not sure yet. But I wrote it MONTHS ago. It consists of 2 minor chords (Em and C#m). The roadblock I'm hitting now is that I'm SO used to this after several months, that any chord change I try to throw in to change up the song simply doesn't sound correct. Sure, I know some songs exist on only 2 chords, but I feel it might be too monotonous. Any suggestions on something to try?
