In any 1x2 formation (e.g., facing dancers, a tandem, dancers
back-to-back), those facing out of the 1x2 formation are called leaders, and those facing into the 1x2
formation are called trailers. A dancer who has one shoulder directly toward the center of the 1x2
formation is neither. In the pictures below, the dancers marked "L" are leaders, and the dancers marked
"T" are trailers. Those not marked are neither.
