Hey that's a cool one. I tried dropping the C down to a B and sounded cool too.

An Em(add9), at least when you drop the C. With the C... hmm... well then you have a sharp fifth, but I'm not sure what to call that. EmAug5(add9)?

Here's another cool one, just a different voicing of Dm(add9) (gotta love those add9s).
