True, but I'm not sure I agree with the first part. I think dance is the least understood. Music, for example, is something you just have to hear. It's a tone that comes into your body and it's something we hear all day long, in the car, in the elevator. A theatrical play, if you know the language, is something that you understand because it is a story.
Most people think linearly and want a story.
Dance doesn't always offer that. People want to feel that they're educated because they like things they know other people like. Modern dance doesn't have that benefit because it is contemporary. This incredible instrument, the body, is also an instrument of great beauty and art. You can't put it away, you use it.
