Music teacher identity is constructed at the intersection between musician and teacher. This study investigated the meaning of music-making among Korean novice music teachers and its role in constructing music teacher identity. Five music teachers participated in this study, and I used two data collection methods, reflective journaling and individual interviews. The results showed that while playing their instruments outside the classroom, several music teachers understood the importance of music in their lives, which was essential in constructing music teacher identities. In addition, playing outside the classroom allowed these participants to demonstrate their musical abilities to students, parents and other teachers and gain credibility as music teachers. However, other participants did not appear to recognise the importance of the intersection between music-making outside the classroom and teaching, which was an obstacle to music-making. Music-making inside the classroom was an important pedagogical tool to teach low-level students effectively. Importantly, regardless of their level of music-making inside the classroom, novice music teachers commonly viewed professional playing skills with primary and secondary instruments as important for teaching.
