This Figure takes 8 bars in all, 2 for each Crossing movement. There is ample Time and so no excuse not to follow, as closely as possible, the rectangular shape formed by the Places in which the Dancers started the Figure, with sharp rotations at each corner. Phrasing within the Figure is important; when, as most commonly, the Dancers start in adjacent Places in The set, they must Travel quickly Across The set and at only half that speed between the Side Places.
Unless a following Figure requires otherwise, this Figure should be completed with a Polite turn; in the diagram, 1st Lady and 2nd Man are on the Inside of The set on the final Cross By the left and so they should continue their natural rotation anticlockwise to Finish Facing Inwards. The Polite turn movement is shown for 1st Lady as also is the more normal Finishing rotation for 1st Man; the Finishing rotation is not shown for 2nd Man or for 2nd Lady.
In a 4-Couple Square set, the 2nd and 4th Place Dancers usually start Across The set in the same way as in a Longwise set though the distance to be Travelled Across The set is slightly greater and so they must move more quickly; the 1st and 3rd Place Dancers usually start Up and down though this is logically the same as for the 2nd and 4th Place Dancers but rotated through 90°. The Barmkin has examples in bars 41-48 and 57-64.
The path may still be a rectangle in a 4-Couple Square set but rotated by 45° so that the Dancers Cross diagonally both Across The set and on the Sides as, for example, in bars 41-48 and 49-56 of The Dream Catcher. 4 Dancers are involved and they Finish in the Places in which they started.
There are many derivative forms: Half rights and lefts is quite common; Diagonal rights and lefts has the rectangular path transformed into a parallelogram; in Rights and lefts in a triangular set, the rectangular shape of the basic Figure is much more distorted; Rights and lefts for 3 couples (or more) have more complicated, overlapping paths though the basic Chain principle of alternating Hands is maintained.
