Teaching the violin, practicing the violin effectively, and enabling people to relax/relieve stress through music are things every musician should do. To explore the role and usage of violin practice, stage style, symphony, and music therapy, this paper takes people of all ages as research objects. It uses a literature research method to analyze the content of violin teaching and music therapy. Through the findings, this article is divided into the following parts: first, violin practice, the relationship between teachers and students, individual playing styles, and a brief overview of band rehearsal/performance are found. Second, the efficacy of music therapy and how to get certified as a music therapist. Music is a kind of language, but it is higher than language, it is a kind of “feeling” like language. Music is an expression of one’s thoughts and a language used to influence the thoughts of others. Music is not so much a language as a sound that exists in everything in the world, and anyone can express their thoughts and emotions with one sound. Music is produced from the human heart and is closely related to human morality.
