The Orchestra Operations Managers oversee the installation of all the materials needed by the orchestra (scores, music stands, lights, electronic equipment, podiums, bulky instruments, etc.). They also devise pit plans for positioning the instruments, calculate the size of the orchestra, and communicate constantly with the conductor and the musicians in order to create the best possible sound.
The Stage Managers are responsible for ensuring that the rehearsals and performances go smoothly. Positioned backstage, they give the cues to the technicians, and make the calls to the artists and manage their entrances, handle security, etc. In short, they communicate constantly with everyone who is involved in the performance and make sure that the show goes to plan.
Once the onstage rehearsals begin, the Lighting and Video Technicians and Sound and Audiovisual Technicians work from the Main Auditorium. Time is specially allocated during rehearsals for lighting and video tests. The lighting designer and the team controls all the lighting effects and input them into a control console. The sound team controls the sound effects, amplification, and feedback, as well as any recordings.
