I never understood the phrase "expressing oneself" through an artform, until just recently.
But I think I have an idea now.
Dancing is like any other form of communication, like a second language. When learning the basics, one does nothing more than communicate, 'I am capable of doing the basics.' But as understanding of the language increase, so does one's ability to express themselves more clearly in the language.
Maybe that's why I like International Waltz so much. If you've hung out with me, you know my voice and overall demeanor reflect "Jive".
Perhaps I have a hard time expressing "Waltz" in English?
