My experiences with Opera Company of Philadelphia, Michigan Opera Theater and Kalamazoo College have helped me in writing this manual on stage management. These experiences have been valuable in learning about the endless and countless responsibilities of the stage manager as well as the running of a professional company. The emphasis of this manual is on the responsibilities of the stage manager working with a professional company (in this case, Opera Company of Philadelphia) producing five shows a season. Stage management at the college level (Kalamazoo College) and touring level (Michigan Opera Theater) is encompassed within this manual. However, some aspects of stage management at the professional, educational and touring levels differ slightly, depending on the type of environment one is working in. The distinction between production stage manager, stage manager and assistant stage manager will be made in the following chapter, after which, the assistant stage manager and stage manager will be referred to as the stage manager. Differentiation between production stage manager and stage manager will be made. Even though my experience centers around stage management with an opera company, the responsibilities of the stage manager are similar to those found in the theater. I hope that this "manual' proves to be interesting to those interested in stage management.
