Is dance a language?

Dance is a language. When we described language earlier on in the semester we had difficulty in saying whether or not music was a language. However, I view dance as an expression of emotions through movement. Music can not say things outright in terms of communications, yet dance can show things that some words can not describe. Many dancers dance in order to express themselves, and their emotions as I had said earlier. Language is simply a way for species to communicate amongst each other, and dancers have used dance as a method of communication. Dancing is used among many cultures as a form of language, even though some is through tradition.
