Dynamics add tension
Today's post is going to focus on moving between dynamics to build tension. In the video above (featuring Bill Heid on keys and Kris Funn on bass), check out how the transitions from loud to soft at 1:07 and again at 2:13 build tension by upsetting the expectation of a loud climax. This upset expectation, and the tension that comes from it are one of the fundamental elements of almost any kind of music. The longer you can delay resolving this tension, the more intense the emotional response from your audience will be. In the video, the dynamic tension in the song doesn't really resolve until the very end.

It's just like a sitcom
Tension and release works in almost any art form. One example of this that may help explain the importance of tension and release is the sitcom. In order for a sitcom to work there has to be some kind of central tension that never gets fully resolved. The reason people continue to watch and enjoy these shows is that they want to find out if and how this tension will finally be resolved. As soon as the central tension is resolved, the story is over. In music the same principle applies, so waiting to resolve dynamic tension until the climax of a piece is crucial.
