This study examined shyness as a potential mediator in the relationship between academic satisfaction and flourishing among Turkish music teacher education students. Using a questionnaire-based survey design, data were collected from 162 (100 female and 62 male) pre-service music teachers. The Shyness Scale, the Academic Life Satisfaction Scale and the Flourishing Scale were used for data collection. The bootstrap re-sampling method was employed using Hayes’s SPSS PROCESS macro. Results of bivariate correlations showed that, higher academic satisfaction was associated with increased flourishing as expected, whereas higher shyness was associated with decreased flourishing. The mediation model was significant for the contribution of shyness. These findings offer useful implications for the instructors of pre-service music teachers and counseling professionals in higher education.
