From parallel waves or eight chain thru formation (if started in eight chain thru formation, the first arm turn is by the right): All arm turn half then new centers arm turn 3/4. Ends facing out circulate half to become ends of a six hand wave. Ends facing in circulate once and a half and keep moving. Meanwhile those in the six hand wave turn half and the new ends of this wave now circulate once and a half and keep moving. The original ends now finishing their circulate once and a half replace these latter two on the ends of the six hand wave. The four dancers in the center of the wave arm turn half, then all six in the wave arm turn half, then the center four again arm turn but this time go 3/4 as the other four dancers move up to the nearest end of waves. Finishes in parallel waves (A Zero Movement ending in waves).
