This paper focuses on musical theater in the high school in British Columbia. It gives a rationale for incorporating musical theater in secondary schools, exploring the impact that a theater program may have on the music program, teachers, students, and community. Further, the paper presents a detailed guide to the process of producing a musical. Following the results of a survey of high school teachers in Vancouver, British Columbia, that elicited their views on producing musicals in school and their motivation for becoming involved, the paper concludes that the benefits to the secondary school and students are many, and that musical theater should be part of a well-rounded program. The paper is in 11 sections: (1) Introduction; (2) Musical Theater--Choosing to Get Involved; (3) Choosing the Musical; (4) Scheduling the Musical; (5) Organizing a Production Team; (6) Budgeting the Production; (7) Auditions and Casting; (8) Rehearsal Schedules; (9) The Rehearsal Process; (10) Sound Reinforcement; and (11) The Performances. A summary concludes the paper. Thirteen references are attached. Appendixes contain a sample questionnaire, recommendations for high school musical productions, an audition form, and a parent acknowledgement form. (SR)
