Eeehhhh, This wasn't quite Trance, more like Ambient Techno.
In fact, there was no Trance to speak of at all. Pretty sure we have some genre mislabeling.
Now, I'd hate to have to explain an entire genre in a NG Review, so instead, here is a useful site:
http://techno .org/electronic-music-guide/ (remove space)
Its a website with a Electronic Music Genre Map, listen to some stuff in the Trance area, espcially Classic Trance, to really understand how Trance is constructed.
I'd also recommend listening to a Trance station on Di.Fm , Its free, with minimal ads.
Still, this is pretty neat, albeit incredibly minamalistic
