On 2nd chord 3c+4c change sides to 1,2,3x,4x. Centro-symmetrical dance.
Note: In »corners pass and turn«, 1c normally pass Rsh on ; for this dance the instructions explicitly specify Lsh
After their second turn, 1c casts to 4pl on  as 4c steps up
A quote: »the key that has always made this dance so wonderful is the flirting that dancing couple can do on bars 9-10 and 13-14 ; <...> if you actually set to your partner, advancing and at the last moment just slipping in BtoB to face and turn the appropriate corner, it's tremendous fun. The moment is all too rare, as apparently few teachers teach it this way, but it's a moment I savour.
[25-32] represent tacking the ship, therefore no polite turns
Espagnole: both W lead RHJ to M side, cross and cast back to exchanged places while Men cross to W side, lead RHJ back to M side crossing to exchanged places ; all turn P EH (2,1)
Note: older instructions tell 1c to turn once LH on 23-24; the current (revised) instructions leave that unspecified.
