Most Scottish Country Dances of this format would be regarded as Ceilidh dances, i.e., fairly easy and usually encountered at weddings or Hogmany events and so with many local variants. Almost always there is Progression around The set, usually with the Ladies going clockwise, the Men anticlockwise, to meet new Partners for the next Repeat as, for example, in The Fairy Ring. Circassian Big Circle is, in one version, a rare example of the non-Progressive form though it is much more commonly performed Progressively.
When space is at a premium, a dance in this form can readily be performed with concentric circles so long as it does not involve any Figure which makes substantial use of the Inside of The set; although Advance and retire does use the Inside of The set, one inner circle can be accommodated provided the Dancers take small steps.
In a rarer form as, for example, Scottish Roulette, Partners Start Facing each other in two concentric circles rather than side-by-side in the single circle.
