Music performance anxiety (MPA) is a widely acknowledged condition in the field of music performance. However, MPA is rarely discussed in the field of music education. Classroom, studio and conservatoire teachers observe their students experiencing MPA related to performances, examinations or auditions, but few have the prerequisite skills to manage the condition. It is therefore essential for music educators to gain an understanding of MPA in order to assist their students. This paper discusses the nature of MPA and its prevalence in the various populations which have been reported in the literature, including children and adolescents, undergraduates, amateur and professional musicians, and music educators. The paper argues that music educators have a critical role in the developmental trajectory of the condition and provides music educators with advice on how teaching practice can ameliorate developing or extant MPA in their students.
