Direction of movement

In ballroom dancing (and in some other types of partner dance), directions of progressive movement, in particular directions of steps, can be indicated either in relation to the room or in relation to the body position.

For example, "backing DC against LOD" means that a dancer is moving diagonally to the center against the line of dance, but as they are dancing backwards, the feet (and, roughly, the body) are pointing diagonally to the wall.

[7] This usage originated from the names of waltz moves and was transferred to other, similar dances.

[citation needed] A commonly stated theory of the origin of the term is that considering the right-shifted position in a couple (even more pronounced in older times) and the counter-clockwise direction of travel along the line of dance, the right turns are easier to perform, they are more "natural".

"Inside turn" is most intuitively clear if initially the couple is in an open single-handhold position facing each other, and the name corresponds to the direction of the lead.

prefer to use this term according to its usage in ballet, based on footwork rather than arm style.

Leader (man) backing diagonal wall and about to step diagonally back (i.e., towards the wall); follower (lady) facing diagonal wall. Explanation see below.
