An orchestra is like a machine that is kept running by the orchestra office. The manager plans concert programmes together with the chief conductor. The finance department manages the money and monitors the orchestra’s finances. The communications department publishes information on concerts and other activities and news about current events in the orchestra. The visual production department provides insights for audiences into the thinking of conductors and soloists and can bring the orchestra to people’s homes. The orchestra manager is the supervisor of the musicians, and the orchestra secretary manages practical things such as hall bookings. Audience outreach work is a form of interaction between the orchestra and audiences. Stage managers prepare the hall for rehearsals and concerts and also find substitutes for musicians in case of illness. The orchestra librarian acquires the printed music required for concerts and delivers it to the musicians.
