Code Brand

First i want to say that i found out recently another website for logo design called freelancer. I know it's not a new thing, but hey, i am just a newbie :)

Well, one of the contest which i was inspired is to make a logo for IT Software house called code melody. My initial concept is making a single music note enclosed within curly brackets but i thought this is too "simple"

So i changed into the one in the right, but i think the music graphs is beyond the word melody (hence i change into harmony)

After a (long) thought, i returned to the initial concept, modyfied into multiple note dan up down version.

As usual comment and critiques are welcome!
