3C Chain Progression was earlier known as Chaperoned Chain Progression
(note by Drewry: This is really two successive 3c dances of 32 bars, the figures of bars 9-24 being similar.
Can be danced in a 3C, 4C or 5C set
Note: The dry white sands on the north-west side of the Isle of Eigg are said to produce a musical sound when walked upon.
On 2nd chord 3c+4c change sides to 1,2,3x,4x. Centro-symmetrical dance.
When setting in the centre, the turn is on the second PdB
Repeat once with new centres and cnrs
In some areas the inner dancers who pass to corners stay facing out, and swivel to face inwards during the setting.
Note: Cosh explicitly tells 1c to pass Lsh in [9-24]; however the Rsh pass is quite common, and nicknamed »Mairi's Divorce«.
