Theater: the lively art

I loved the idea the Professor Fusi talked about in lecture the other day: that theater describes the human condition. Theater: the lively art touched on this as well on a theoretical way, but I'm really interested in the practical usage of this. If theater describes television, movies, musical performances, and dance, that means that each of these kinds of performances describes a part of the human condition. I think that the human condition should be noticed more in these forms that often focus on entertainment value, what will make the audience happy, rather than what will add the the description of the human condition. I have gone to many concerts where I have love the beat, the lyrics, and the spectacle, but rarely have I thought about what the song is representing: the emotions, what it meant to the songwriter when they wrote those lyrics.
For mme, dance is something that I watch, but don't necessarily connect with the human condition. But each movement, each formation can describe the stories and thought that go on in everyday life.
