what do you mean?
Sounds like it has a progression to me. Sounds like you start with on chord structure go up to another, than up to another than you bring it down to the one you started on and you sort of repeat those chords.
I might be wrong, I don't have a formal music theory background, but this is far from what I'd call a simple melody. But whatever, you're the one who made it, you can call it whatever you want. I'll just say that it's pretty good. Maybe a little more peaceful than I'm used to, but none the less decent.
