This feminist study examines women's use of improvisation in discovering, creating, and articulating various self-identities. To create a theory of identity formation, two feminist theoretical position, essentialism and poststructuralism, are analyzed and merged. This hybrid theory addresses the interplay between the self and society that women must recognize in order to form satisfying identities. Improvisational practices, involving bodily awareness and movement, are demonstrated to have the potential for helping women to actualize themselves in these various identities. For this study, the writer uses her experience as an improviser and interviews three women who use improvisation in their choreographic processes. She also discusses performers whom she has seen and performers about whom feminist performance critics have written. This study examines improvisation in dance and performance art from a feminist perspective. I clarify what improvisation entails and, by doing so, illustrate how improvisational movement in dance and performance art can enhance the lives of women as viewers and performers. Through exploring improvisation from this feminist perspective, I demonstrate the psychological insights I have gained from practicing improvisation and document performances that have been improvisationally inspired by women who feel dissatisfied with the manner in which this society shapes and limits their identities.
