In musical education, children and young people are often confronted with stage fright or music performance anxiety (MPA) in performance situations at an early age. It is, therefore, an important task for music educators to teach young musicians coping strategies for dealing positively with MPA. Evidence-based concepts are available for this purpose, which are based on the student as a person, the musical task, and the performance context. Tools such as the Stage: Cool app enable young people to receive feedback on how they deal with MPA during a performance by answering test-theoretically based questions after a performance. Self-efficacy has a significant influence on the success and satisfaction with the performance. If positive experiences with performances are provided early on in singing and instrumental lessons, this can provide significant resources for further personal development in the areas of self-efficacy and performance skills, which can also have a positive impact outside of the field of music. To date, there has been little discussion of the fact that dealing positively with MPA can also be seen as a resource for the development of children and young people.
