Physics of music is an area that is covered by interdisciplinary approach. In this study it is aimed to determine prospective music teachers' level of association with physics concepts which are related to music. The research is a case study which combines qualitative and quantitative methods. Eighty-four students who were studying at the Department of Music Education participated to the study. A data collection instrument which included qualitative and quantitative items with an interdisciplinary approach was used in this research. The collected data were grouped and analyzed by finding percentage value for each item. The findings from the data analysis were interpreted and a case assessment was made. In addition it was asked if it was necessary to take such an education. The findings revealed that most participants were unaware of musical concepts relating to physics and had difficulty in associating these concepts or expressing what they know. However, a great majority thought that such an education was necessary in their department.
