Scottish ceilidh dancing is done at parties, weddings and of course at Hogmany.
Ceilidh dances tend to be simpler than dances in Country Dancing, indeed some ceilidh dances are simplified versions of their country dance counterparts.
They are also usually quite energetic dances and some have a twist to make them more fun. E.G. in the dance "The Drongo" one extra dancer stands in the middle of the set, at the end of the dance this person is included in the last formation (5 hands across). The music is stopped at random and the 5 dancers must rush to a new partner (of the 4 dancers standing in the set). The dancer who does not get a new partner becomes "The Drongo" and must stand in the middle of the set for the next turn.
