The author describes her process of utilizing collaborative musical theatre as a teaching tool in three settings. These include an elementary school in the Bronx, New York, which adheres to the theory of Multiple Intelligences; undergraduate and graduate music education courses at Lehman College, City University of New York; and in a College/Community Collaborative Musical Theatre Project at Lehman College. The chapter depicts how the collaborative process closely resembles the goals of the Multiple Intelligences theory by the way it stimulates, encourages and nurtures the many capacities and ways of expression of the participants: Intrapersonal, Interpersonal, Mathematical/Logical, Spatial, Kinesthetic, Linguistic, Musical and Naturalistic, and therefore, serves as an effective, all-encompassing teaching tool.
