Thanks all for your posts! Well, it's an interesting point that you have written. It's hard to explain what I define intense in Yoda's Theme. Yes, it's only a theme but with only few notes he transform it to pure magic. I compare it mostly with Schuberts String quintet D 956, the second movement: Only 94 bars and how much intense! Of course, that doesn't mean if Williams uses less notes then it is more intense. The Jaws-Theme has two notes and there is no intense IMO. But most action sequences aren't "made" to show intense: There are particular rhythms and structures and it's gone very fast so I can concentrate on orchestral subtleties. So I would say that I perceive intense if I can gather the whole thing.
