How is the WL positioned in the Fourth Intermediate Position?

In Fourth Intermediate Position, the working leg (WL) is indeed positioned diagonally forward at a 45-degree angle from the Line of Direction (LOD). This specific positioning allows for a balance of aesthetic appeal and technical correctness in Highland dance. The diagonal forward angle contributes to the dancer's line and extension, which is vital for demonstrating grace and precision in the dance.

This positioning also facilitates greater mobility and effective transitions between movements, as it prepares the dancer for various steps and actions that may follow. By maintaining the WL at this angle, the dancer is able to maintain an open frame and a strong alignment, which is crucial for executing high-quality movements throughout the performance.

In contrast, the other choices would not align with the established technique of Highland dance. For example, having the WL at a 90-degree angle from the rear would disrupt the flow and balance required in this position, while positioning it directly to the side would limit the dancer's range of movement and aesthetic expression. Additionally, simply having the WL in contact with the ground does not clarify the required placement for the Fourth Intermediate Position and does not enhance the visual or technical components of the performance.
