a strange music box

Hi, This is something i have made long ago with midi sequencer. There is a strange, short music box melody that repeats 3 times and then i have just added some strange instruments to the background that start to play over the melody. The music box line is fine to me, i could use it in new composition. The notation is very bad, it is in midi form. 

I would ask you if you're trying to do something that builds in organized layers, or if you want to really break down and go wild? It might be easier to just loop the first 10 seconds of the music box melody and work with that, it is an engaging sound. Otherwise it might be hard to add layers on top of it.
