The most common formation is the parallel line. In this formation, the dancers dance in a synchronized manner, but independently of each other. There are usually no moves that require any interaction between the dancers, other than they execute the maneuvers at the same time. Each dance has a different sequence of movements that must be learned.

There are several variations to this parallel lines set-up. There may, for example, be two sets of lines where the dancers face in directly towards each other. In larger groups these will become several sets of in-facing parallel lines. In these "contra" line dances, the dancers will dance with the others in the facing lines.
