As society and technology develop, the importance of interdisciplinary research becomes more apparent. The purpose of this study is to present the convergence of music and digital therapeutics(hereafter 'DTx') in the research and development of the medical system and ICT. This study was conducted by separating DTx and music intervention and analyzing their separate trends and results of convergence. The current Dtx exists mostly in the form of mobile applications that provide cognitive behavioral intervention for mental health such as insomnia, anxiety, and depression. The current applications are developed with the importance of medication, symptom management as well as improvement in mind. Through the cases of DTx provided in this study, the fact that the effects of and technology for musical intervention can be enhanced by interdisciplinary convergence can be seen. Music holds value as part of a healthy lifestyle and as part of the digital health setting. For further development of the interdisciplinary convergence of music and DTx, we should seek out the knowledge of professional musicians and encourage their participation in the convergence research and development.
