The purpose of this research study was to quantitatively examine South Carolina high school instrumental music students' self-efficacy as measured by the Generalized Self-Efficacy (GSE) instrument (Schwarzer & Jerusalem, 1993). The independent variables of age, experience, gender, ethnicity, and type of instrument played) were correlated with the dependent variable of self-efficacy for South Carolina music students in the 2008-2009 school year. A total of 109 surveys were completed from 800 participants solicited (i.e., 13.6% survey response rate). There were no statistically significant relationships between the music experience and self-efficacy; and no statistically significant differences in self-efficacy as delineated by gender or ethnicity.
