Line Dancing

Line dancing is a form of choreographed dance that takes place with a group of people. Participants line up in rows and execute the same movements in a synchronized manner.
Everyone dances alone, side by side, facing the same direction in lines or rows. …. Each dance consists of a sequence of steps that are repeated throughout the music. Although a variety of music may be used, the major emphasis is on country-and-western music.

Each dance is said to consist of a number of walls. A wall is the direction in which the dancers face at any given time: the front (the direction faced at the beginning of the dance), the back or one of the sides. Dancers may change direction many times during a sequence, and may even, at any given point, be facing in a direction half-way between two walls; but at the end of the sequence they will be facing the original wall or any of the other three. Whichever wall that is, the next iteration of the sequence uses that wall as the new frame of reference.
