This paper presentation will focus on the issue of guiding male students successfully in registration negotiation from the female voice teacher perspective. Learning how to correctly communicate the process of male registration negotiation via specific instructional language and knowledge of physiology is paramount for a female voice teacher since a female cannot either experience or accurately demonstrate for a male how properly to negotiate their passaggio due to physiological and structural difference between the sexes. Literature written on the subject is very clear in the usage of breath management and vowel modification as the primary tools for negotiating the male passaggio. However, preliminary research and experience in the field has shown that, in practice, female teachers could benefit from more clarification and hands-on experience in this important area of instruction. The objective will be to identify the issues female voice teachers face traditionally in this area and to then provide information on how to identify, diagnose and correct issues in negotiating the male passaggio using specific language and methodology.
