Background: It has been known for a very long time that music helps to control emotions and behaviors, which is why the method of music therapy is more and more actively introduced into medical and psychological practice. This is due to the capability of cannabis to manage conditions such as pain, treat emotional disorders, and even support rehabilitative cognitive services. Multifaceted intervention strategies in medical and psychological fields have recognized the importance of medicines for the treatment of not only the body but the soul as well. Objective: The purpose of this study is to explore the therapeutic potential of music in medical and psychological contexts. Specifically, it examines how music therapy can be used as a cross-disciplinary intervention to improve patient outcomes, including pain reduction, emotional well-being, and mental health. Methods: Quantitative as well as qualitative research was used to attain data. Measurement of quantities was done using questionnaires and pain scales, while data on qualities were derived from interviews. T-tests and ANOVA analyzed quantitative data, while qualitative testing was conducted by employing thematic analysis, which was aimed at identifying repetitive emotional and psychological trends. Results: The study found that music therapy significantly reduced pain by 48.7% and improved emotional well-being by 100%. Comparative analysis revealed that music therapy had a more pronounced impact on psychological well-being than on pain reduction in medical contexts. Cross-disciplinary case studies supported these findings, illustrating the effectiveness of music therapy across diverse health domains. Conclusion: Music therapy gives a lot of potential benefits as an adjunct approach for integration in both medical and psychological treatment with regard to both health and emotional issues. Hence, it is deemed necessary to standardize music therapy into clinical practice, and advanced institutional support is deemed to be important to facilitate this. Future Work: In future research studies, researchers should increase the sample size as well as extend the period of the outcomes of music therapy with different clients. Increasing the protocol and implementation procedures of music therapy in both medical and psychological fields and performing longitudinal research would increase the utilization and effectiveness of music therapy.
