I want to know the answer to the following question:
What did Chopin add to the modern dance of his era?
All the background I'm provided with is that "Chopin's mazurkas, while originating in the traditional Polish dance (the mazurek), differed from the traditional variety in that they were written for the concert hall rather than the dance hall; "it was Chopin who put the mazurka on the European musical map.". Is that enough to answer the question?
