A considerable amount of study has been devoted to the development of the adolescent male singing voice. By comparison, little attention has been given to the study of the adolescent female singing voice. However, in recent years, there has been increased interest in information regarding the girl’s voice during adolescence. In addition to providing a comparison of male and female adolescent voice change, this chapter reviews the physiological changes as well as symptoms associated with vocal development in the singing voice of adolescent girls. Further, the chapter outlines phases of vocal development as well as criteria for classification according to developmental phase. Finally, the chapter provides a review of research/literature on the topic of the female adolescent singing voice, as well as research regarding self-identity, singing, and adolescent females.
