Exploring the Effects of Vocal Training Programs on the Skills and Development of Chorus Performers

Vocal training is a crucial component in developing a singer's vocal capabilities. It enhances the vocal quality and improves the overall vocal health. Through consistent practice and well-structured exercises, singers can achieve high control, clarity, and expressiveness. In this research, we aim to investigate the impact of a structured vocal training program on older choristers. This research includes 18 older choral singers (with ages above 50 years), randomly assigned to either the study group or control group. Data were gathered through pretest and post test assessments of vocal function using perceptual voice analysis, self-assessments, and acoustic evaluation. The vocal training program was exclusively performed for the study group. Additionally, participant feedback and program effectiveness were collected through structured interviews. Respondents in the study group indicated substantial improvements in perceptual roughness, vocal clarity, jitter, shimmer, and pitch accuracy following the training session. However, assessments of subjective breathiness and effort, as well as phonational frequency range, revealed no significant differences. The participants also reported that the training program had a favorable impact on their voices. Overall, the findings suggest that structured vocal training can significantly enhance certain aspects of vocal performance in choristers. This research highlights the potential benefits of vocal training programs for improving vocal health and performance quality for older choristers.
