MT (multimedia technology) music teaching has changed the rigid, unitary, and boring teaching form of traditional music teaching, which has made a comprehensive breakthrough and impact on traditional university music education and has shown a brand-new teaching form to contemporary college students, greatly increasing their strong interest in learning music. In this paper, an objective evaluation method of vocal music quality based on the comparison of sound parameter characteristics is proposed by using the technology of sound signal parameter analysis and extraction. Through confidence measure, reliable data are selected for online adaptive updating of Gaussian mixture model, and the recognition results are smoothed to further remove the instantaneous mutation error. The main melody of singing is discriminated by fundamental frequency discrimination model. Experiments show that the overall accuracy rate of the main melody of vocal music extracted by this algorithm is 86.24%.

Public music education in universities can promote the improvement of students’ moral feelings, the cultivation of students’ cultural quality, and the development of students’ physical and mental health. Music education is an essential part of quality education in universities. The relationship between music education and Fujian ecological culture is investigated in this paper. The evaluation index system of regional music education and Fujian ecological culture construction is constructed from five aspects, green economy, social development, resource conservation, environmental pressure, and ecological culture, based on GA (genetic algorithm) and regional characteristics of music education and Fujian ecological culture construction. The principal component clustering coupling model is built on this foundation. According to the findings, Fujian’s ecocultural construction is still in the process of coordinating and integrating economic, ecological, and cultural systems, and it is necessary to follow the path of regional integration, coordinate the development steps of each subsystem as a whole, and promote the region’s coordinated development.
