As an important part of Chinese culture, ethnic vocal music culture contains rich cultural and historical connotations and fully embodies the national spirit of a nation. As an important place of education, schools integrate traditional music culture into the school music curriculum. The dissemination of traditional music culture plays an important role in the inheritance. In this paper, we use 3D animation and 3D roaming to construct the virtual environment of the national vocal performance environment as well as the content of the music curriculum, adopting the concepts related to the classical scene to the contradictory space to realize the scene interaction. The DBSCAN algorithm is used to preprocess the vector data collected from geographic, remote sensing and topological vectors. Texture, lighting, and shadow effects are added to the scene rendering to enhance the realism of virtual reality interactions. Monte Carlo simulation is employed to denoise the generated virtual scene and optimize the environmental scene of ethnic vocal performance. Evaluating the effect of teaching use of the model, students’ motivation to learn ethnic vocal music was improved compared to the pre-test. The average difference between the pre and post-tests was 1.6102. The P-value of the sample test for each question item was 0, which is less than 0.05, indicating that students’ motivation to learn ethnic vocal music has undergone a significant change. In the teaching feedback, the number of students whose cognitive level of ethnic vocal music reaches level 2 or 3 is 148 in total, accounting for more than 90% of the total number of students, and the teaching of the simulated performance environment improves the student’s ability to feel and other abilities of ethnic vocal music to a certain extent.
