With the development of computer technology nowadays, how to incorporate the modern technology into music teaching has become an important topic to discuss. In this paper, I will explore the teaching methods using the modern technology for music teaching, and propose a music performance evaluation system using simulated annealing algorithm to evaluate the music performance of vocal music player. The music performance evaluation method designed in this paper is able to precisely determine the performance level of music players and help students to receive feedback. After using the modern technology and the performance assessment model for music teaching, the experimental students’ concentration level showed significant differences from the control students at the 1% level in all sections, and the overall concentration level of the experimental students increased by 15.19%. The experimental students whose concentration and relaxation scores were above 60 were 37.78% and 22.22% higher than the control students, indicating that the application of modern technology and the model in this paper can effectively improve students’ concentration in traditional music learning and promote students’ efficient music learning.
