The Dances and the Music
A short history: Danish folkdance is very old. In fact most dances are from around 1780-1880. That might not sound that old, but the fact is, that most other countries has folkdances that is much younger... (from 1840-1930, actually).
The Danish dances were danced by the farmers and the poor people (that's why it's called folkdance - dances for the mass). These people wasn't allowed to dance the dances danced in higher circles - for example the were not allowed to dance menuette (french dance - very popular in noble circles in the 16-19th century) and dances like that. Instead they had their own dances which could be quite advanced. There were ring-dances, 2, 3 and 4 pair dances, 3-person dances (if there was a shortage of men each man had two female dancers ...), 8-pair dances, and row-dances. And, of course, single pair dances. The dominating types are 4-pair dances and the ring-dances.
