The dances in this era might look “basic”, comparing to today’s big, flashy and fast dances today. I wouldn’t call it an improvement though, but more of a different kind of dancing. Because an “improvement”, or “evolution” usually means keeping the best parts of the old, and create new better things. But today some of the very best elements are harder to find. For example, the natural movement, the comfortable feeling between man and woman, the sensitive hands and articulate feet and legs. They are gems from this era.
