…key changes in TV theme songs.
You wouldn’t think a TV theme song would be long enough to support a key change, but I’m thinking of a popular theme song that had a legitimate key change. If it matters, when I say “popular”, this might be another one of those cases where it matters that I’m a little older than everyone else and you may have never heard of the show at all. So, that’s a useful hint: think of a show you might never have heard of.
It’s a pretty good key change. The melody changes a little at the key change in an interesting way.
