Classical music is a treasure of human civilization, carrying a profound historical and cultural heritage. Entering the new media era, the dissemination and development of classical music are facing new opportunities and challenges. Currently, the social communication mechanism of classical music in digital media is mainly through short videos, virtual experiences, music communities, etc. These social communication mechanisms and the artistic value of classical music have formed a relationship of mutual promotion and balanced development. This paper uses logistic regression and structural equations to empirically analyze the interaction between the two. It is verified that the above three social communication mechanisms can enhance the perceived artistic value of classical music audiences, and that the artistic value of classical music prompts the transformation of digital media. However, the current social communication mechanism also brings problems such as homogenization of content and weakening of artistic integrity. In response to these problems, strategies such as encouraging original creation, optimizing the form of dissemination, and creating exclusive zones can effectively improve the efficiency and quality of classical music dissemination and achieve its sustainable development.
