Trance is not only defined of having a higher bpm in compared to House. But also on it's highly emotive narrative structure.

They typically have “huge” emotive chord progression which takes the listener on a ride. Also, almost every trance song will have a distinctive breakdown where most of the elements are stripped down, and then put back piece by piece usually ending with snare-rolls and crashes.

If there is one word to describe a trance track, it would be epic.
