Music teachers enjoy carrying out teaching tasks; indeed, such pleasure may be perceived even when authoritarian pedagogical methods are applied. In this study, we will explore music teacher motivation in classroom settings, collecting data from three educators through psychological scales, lesson observations and personal interviews. Results indicate that teacher motivation in classroom settings is affected by five internal and five external factors. Therefore, the study allows concluding that teacher motivation is also satisfied or thwarted by ideas that school members have about music education. Some practical implications are suggested.
