Because the importance of experienced teachers is growing, retaining experienced music teachers has become a major issue among educators. Therefore, it is necessary to listen attentively to what kinds of difficulties experienced music teachers perceive and to think about how to help these teachers so that they can successfully perform in their own music classes. The purpose of this study was to explore the difficulties in music classes that experienced Korean primary teachers perceived. The results of this study indicated that the teachers showed concerns regarding their own musical abilities, traditional Korean music, and students' motivations for music learning. Implications of the findings for music teacher support are provided.
