I am trying to find a chord to follow a B6 chord. The melody I am writing sounds really nice, and I have noticed the first part follows the E6 chord, then the B6 chord, so my thought is that if I can find another chord to fit this progression, it will help me finish my melody. I guess that would mean my "chord progression" so far is E6 then B6
...
I know enough music theory to get around (at least for electronic music), but I am not perfect at it. I would really appreciate any input as to the direction I can take to resolve this melody nicely! (I am aiming for a bittersweet melody. Happy, but with a sad undertone if that means anything)
Thank you so much for your time! I normally don't post on stackoverflow for music (I am a computer programmer so I use the programming section quite a bit though), so please let me know if I am missing anything!
EDIT: Ultimately I am writing a melody. Just thought I would clarify.
EDIT 2: The key is B major! (or G# minor I guess. The tonal center of this particular melody is hard for me to judge.)
