What purpose does a rider serve for a theatrical company?

A rider serves as a comprehensive document that outlines all the specific technical requirements necessary for a theatrical performance. This includes details such as lighting preferences, sound equipment needs, stage setup, costume specifications, and any other logistical considerations essential for the successful execution of the show. Providing a rider ensures that everyone involved—producers, technical staff, and venue operators—has a clear understanding of what is needed to create the desired production environment, ultimately enhancing the performance quality and audience experience.

The other options address different aspects related to a theatrical company but do not align with the specific function of a rider. For example, a record of past performances relates to documentation and history, a schedule of upcoming shows pertains to planning and promotion, and a promotional flyer serves a marketing purpose rather than technical needs.
