Ceilidh in England has evolved a little differently from its counterparts elsewhere in Britain and Ireland. English ceilidh, sometimes abbreviated to eCeilidh, can be considered part of English Country Dance (and related to Contra). English ceilidh has many things in common with the Scottish and Irish social dance traditions. The dance figures are similar using couples dances, square sets, long sets and circle dances. However, the English style requires a slower tempo of tune accentuating the on-beat, the central instrument often being the English melodeon, a diatonic accordion in the keys of D and G. Dancers often use a skip, a stephop or rant step depending on region. This contrasts with the smoother style and more fluid motion seen in Ireland, Scotland, or (the walking) in Contra. Many ceilidh dances involve a couple, but this does not limit the number of partners any one dancer has during the ceilidh. Often dancers will change partners every dance to meet new people.
