A circle of dancers that are facing alternately in and out--all have hands joined (either hands up with palms together or forearm holds). This formation was part of an entire dance: Allemande Left in the Alamo Style, right to partner and balance awhile. Balance in and balance out, turn by the right hand half about, balance out and balance in, turn by the left you're gone again, balance forward and balance back, turn by the right on the inside track, balance out, back to the land, turn by the left do a right and left grand.
