Vector signs; Free space lines. The most extensively used graphic sign system in Choreographie is not given any name in the text, but the signs have been translated as indicating directional-motions and so might be considered ‘vectors’ (Longstaff, 2001). Similarly, they are likened to “free space lines” described later in Choreutics:
... a notation is needed that makes it possible to record any desired inclination which may occur at any place, either inside or outside the kinesphere, without being bound to the points of the scaffolding... [For] notating free space lines... the vertical remains the only reference and inclinations are related to themselves. (Laban, 1966, p. 125)
The signs are defined in Choreographie to be equivalent with inclination numbers, as demonstrated in the Axis-scales (Fig. 25). In the same way, the vector signs are used as transverse inclinations in the sequences titled “augmented three-rings or double-volutes with one action-swing-direction” (Fig. 26) and “volutes with volute-links” (Fig. 27). These scripts begin to reveal how vector signs use the same concept of flat, steep, or suspended inclinations (deflecting diagonals).

The sign system looks more complete when the diagonal signs (see Fig. 18) are placed next to the vector signs exhibiting their similar shapes. Each inclination sign can be seen in the same graphic structure as a diagonal sign, modified to indicate its deflection as either flat (lateral), steep (vertical) or suspended (sagittal) (Fig. 28).
The similarity of diagonal signs to vector-like signs raises again a question of whether the diagonal signs always indicate positional-directions as considered earlier (Fig. 18). While the diagonal signs are not used in any of the notated sequences in Choreographie, they obviously share their graphic and conceptual structure with the vector signs.
