Some Round the room sets for single partner groups are Progressive by Partner, others not. For the latter, while it may stretch the logic to regard Ballroom and Sequence dances as being performed in Sets, Ceilidh dances such as The Gay Gordons and The Schottische must not be excluded from the Scottish Country Dancing répertoire. In any event, their inclusion in a Scottish Country Dancing Ball programme adds to the musical and the dancing diversity.
In those Round the room sets for single partner groups which are Progressive by Partner, the single Partner group Starts either in a line Facing anticlockwise or side-by-side Facing Inwards or Facing each other in either of these Directions. At some time during the Repeat, the single Partner group breaks up into its constituent Dancers who then form new Partner groups with Dancers from adjacent Partner groups for the next Repeat. For example, in Ardailly Mill, the Active set consists of one Man between two Ladies, Starting Facing anticlockwise; at the end of the Repeat, each Man Progresses anticlockwise to perform the next Repeat with the two Ladies in the next Place who do not Progress.
Note that it is not convenient to try to adapt dances of this type to a Longwise, Full set format (as is possible in Round the room sets for pairs of Partner groups) because, as one part of the Partner group reaches the Top, the complementary part needed for the new Partner group will be at the Bottom. Sometimes, too, the single Partner group makes use of adjacent Partner groups for certain parts of the Repeat.
