All this to say simply that our dances have a history to them, They are an ever evolving dance form, but it did come from somewhere. Great example is the ever popular "Petronella" balance and spin one place to the right. There actually is a dance called Petronella and I would guess that 95% of those dancing today have never danced the original Petronella, even though the caller directs, "Balance and Spin one place to the right, as in Petronella". There are hundreds of dances out there that do not get danced today because they do not fit the desires of today's faster, more gotta swing culture. Sometime I think we are loosing a little of our own heritage.
