Student Thesis: Perceptions of Undergraduate Vocal Music and Theatre Majors on Vocal Health Education

Heather Smith 

The purpose of this study is to gain insight into the perception of the vocal health education that music and theatre majors are receiving in their undergraduate programs to prepare them for lifelong careers as professional voice users. A survey will be administered to determine perceptions in the following areas: instruction in vocal hygiene, preventative strategies for the performing voice to enhance care of the voice (including care for the speaking and singing voice), and the nature of the vocal instruction (including technique and protocol for vocal rehabilitation when experiencing a voice problem). The study aims to gain insight into potential areas of weakness in order to improve the training young singers are receiving in their education as it pertains to vocal health and technique.

Student Research: Student Attitudes Towards Individuals with Voice Disorders 

Kristin Campolongo, Brianne Garretson, Victoria Marley, Heather Smith, Allison Waters, & Chayadevie Nanjundeswaran

The purpose of the study is to identify student attitudes towards individuals with voice disorders. Specific questions include: (a) if a voice disorder will lend to a negative perception towards individuals with voice problems (b) will the perception be different between a teacher and non-teacher, (c) would the negative perception impact the trusting relationship between a student and a teacher and (d) will the age, gender, and grade of a student influence the perception.
