Everyone changes their facing direction by 180°. EN: 40

Centers should take a slight step forward before doing the Cross Run. This makes the movement smoother for the Ends, as it gives them room to move into the center. EN: 50

If both Centers start facing the same direction, they pass Left-shoulders with each other since they are doing a Centers Cross Run (Half Sashay and Run). EN: 60

The original Ends should move into the center without changing their facing direction and then do the Trade. Do not change your facing direction as you move in, as it may confuse others, and make it difficult to properly do the Trade. The confusion occurs because the other End might not be aware of your original facing direction, and hence would not know whether to do an Arm Turn 1/2 (from a Mini-Wave) or a Partner Trade (from a Couple). EN: 70

Swing & Mix was the original call, and was later generalized to be anything & Mix. EN: 110

Swing & Mix is no longer explicitly listed on the CALLERLAB A2 list. However, the calls Swing [A2] and Mix [A1] are on CALLERLAB lists. In our opinion, Swing & Mix should be listed on the A2 list as a separate call because it can be done from Facing Couples. According to the current CALLERLAB definitions, a Swing & Mix is a Swing followed by a Mix. Swing, as defined by CALLERLAB, must start from a Wave or Inverted Line, not Facing Couples. Swing is defined as Ends and Adjacent Centers Arm Turn 1/2. However, Swing & Mix is still widely called from Facing Couples, and it should be legal. EN: 120

Swing & Mix is a 3-part call due to historical reasons. EN: 130
