I feel that they put tension in their music. One of the ways they may be putting tension in their music: Whenever you play notes that do not agree with the chord being played, and then quickly resolve it back to a chord that blends you have created tension. A simple but effect thought. That works best with the brass instruments.

I am sure there is a good size list that they use like – change in volume and what’s in their hearts. If it’s good it’s always the guy who is playing
