Which of the following arrangements typically requires less mobility from the audience?

The arrangement described as "End-On/Proscenium Arch" typically requires less mobility from the audience because this setup places the performance area directly in front of the audience, who sit in fixed seats facing the stage. This arrangement is designed to provide a clear view of the action without requiring the audience to move around to see different perspectives.

In contrast, arrangements like "In the round," "Promenade," and "Thrust" involve configurations that usually necessitate more audience movement or adjustment. For instance, "In the round" surrounds the stage, which means audience members need to turn and shift their positions to view the performance. "Promenade" encourages movement as the audience walks or moves around the performance space, often following the action as it unfolds. "Thrust" extends into the audience space and may result in varying viewpoints, requiring audience members to shift their sightlines.

Therefore, the End-On/Proscenium Arch arrangement's fixed and frontal seating creates a more stable viewing experience, minimizing the need for mobility.
