Punctuation.!?

So there is a show i watch quite a bit that has some of the most pronounced punctuation that I can think of. The show is called Corner Gas it is a sitcom from Canada that airs on WGN. For pretty much all their transitions to commercials they have the same sound of three notes on a guitar. I'm not sure if this would qualify as punctuation or not but this seemed to be the best example that I could think of. It kind of lets you know when the scene is over and brings a wrap to what was going on in the story. This also brings a kind of signature to the show because they use is so prevalently throughout their episodes, along with some of the other sounds they use in their transitions to scenes. They will use this kind of whipping sound to jump to a short shot of another character (usually being talked about in the scene), and back to the original scene. This sound is also used alot in Scrubs. The sound also acts like a ellipsis in the show when they cut to a another situation with other characters.
