In Scottish Country Dancing, the 4-couple square set is by far the most common of the Circular set formats.
As in all Circular sets for Couples, the 4-couple square set is formed by the Dancers being evenly spaced in a circle with the Ladies Standing on the right of their Partners. The Top couple is that nearest The music; Couples are numbered clockwise starting from the Top as shown in Diagram 20.
There is usually no Progression, the dance being performed once through with all Couples having an equal part. There may be a Chorus at the beginning and the end and sometimes also at one or more intermediate points; these Choruses may demarcate repeated sequences, led by successive single Dancers as in The Buchan Eightsome Reel or by two Opposite Couples as in Nottingham Lace and in Ian Powrie's Farewell to Auchterarder.
In those few dances where there is Progression, the dance is normally performed with the dancers Progressing round the Square set in four Repeats, as in Rothesay Rant; when there are two Dancing couples, there may be only two Repeats, as in The Haunt of the Gnomes.

At the start of the fourth repeat following the progression, 2341, or of the second repeat following the less usual progression, 4123.
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 4, 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 4, i.e., in Helvetica font in the lower right part.
