Facing Dancers
Dancers move forward, passing right shoulders with each other and end back-to-back.
Back-To-Back Dancers
2
Man's right shoulder slightly forward as right shoulders pass. Arms in natural dance position. Woman works skirt with hands, right hand leading as right shoulders pass.
Pass Thru is proper from a Right-Hand Mini-Wave because of the Ocean Wave Rule. It is the same as Step Thru.
Pass Thru is improper from a Left-Hand Mini-Wave because of the left shoulder pass. Use Step Thru instead.
Pass Thru from a Left-Hand Ocean Wave, making use of an implicit "those who can", and expecting only the centers to be active is rarely used and goes against dancer expectation. Use "Centers Pass Thru" or "Centers Step Thru" instead.
From a Squared Set, Heads Pass Thru is proper. It ends with the Heads back on Squared Set spots. See Squared Set Convention.
Pass Thru is improper from dancers who are further apart than directly facing, or on a diagonal with respect to each other. Using a phrase like "Boys On A Diagonal, Pass Thru", the caller can accomplish the desired dance action.
Pass Thru is proper from a Couple facing an individual Dancer. In this case, the Dancer splits the couple, having the effect of passing one dancer right shoulders and the other dancer left shoulders.
