The purpose of the research was to examine the awareness and insight of training of music therapists with inferiority feelings. Being the subject of this research, I was able to collect data during the training process of music therapy from 2011 to 2016. The collected data is based on the emotions and values in accordance with inferiority feelings. Therefore, collected data were analyzed and described through the method of autoethnography. As a result, I found that being a ‘middle child’ and having a ‘negative portrayal of myself’ were causes of my inferiority feeling, and hidden under the façade of this inferiority feeling were an ‘wounded inner child’ and ‘indignation of other people’. Moreover, by providing an insight for my inferiority feeling, I was able to accept myself and to find therapeutic resources as a music therapist. This research is significant in that inferiority feeling of a trainee during music therapy training was provided with a delicate and detailed insight. Finally, the results of this research provided an example of trainees’ various emotions, including inferiority feeling, by illustrating the course of being aware of and having an insight on inferiority feeling felt during training of music therapy.
