3-Couple Triangular Set.
At the start of the third repeat following the more usual progression, 231, or of the second repeat following the less usual progression, 312.
Note that the numbered Places of the Dancers in the Full set (the Places in which they started the dance) are shown as 1 2 3, i.e., in Times New Roman font in the upper left part of the Dancer's symbol; their numbered Places in the Active set (the Places in which they started the Repeat) are shown as 1 2 3, i.e., in Helvetica font in the lower right part.
In The Swelkie, the Progression involves changing Partners though all are back with the original Partner at the last chord of the dance. The mathematically minded will recognize that this arises because the Progression for the Men, 312, is different from that for the Ladies, 231.
Given that most Scottish Country Dancers have so much difficulty in positioning themselves correctly in this Set format, while Making up they should all Take hands in a neat circle; they should then move round as necessary so that the Top couple are aligned Across the set, as they would be in a 4-Couple Square set. When not required to Face Partner, every Dancer in a Triangular set should take care to Face the Opposite Dancer. It is most important that the 2nd and 3rd couples should never align themselves as though they were 2nd and 4th couples of a Square set.
Each Dancer should maintain the correct shape of the Triangular set by checking his/her Position whenever back to one of the Starting Places. Some dances, such as The Wind on Loch Fyne, use Figures particularly suitable for Circular sets and so the Triangular set format can readily be maintained, throughout; others, such as Indian River Strathspey, use Figures which have to be distorted from their use in Longwise and Square sets, making the Triangular set format more difficult to maintain.
