This article discusses an innovative teaching model that integrates the theory of multiple intelligences into music education, including the design of teaching strategies and evaluation frameworks. Using fuzzy theory and credibility mechanism, the article proposes a fuzzy comprehensive evaluation model for assessing the quality of music teaching. The model realizes thorough evaluation by determining the evaluation set and the single-factor judging method. The study takes two classes of music majors as an example to conduct the factor analysis of the Students’ Music Performance Rating Scale and finds four main factors with a cumulative contribution rate of 33.36%. The results showed that the experimental group applying the Multiple Intelligences teaching strategy was significantly higher than the control group in music performance. The post-test after one year teaching experiment showed that the students in the experimental class showed highly significant improvement in bodily-kinesthetic intelligence, musical intelligence, and self-cognitive intelligence (P<0.01), as well as linguistic, spatial, and interpersonal intelligences (0.01<P0.05). The study confirms the practical application of multiple intelligences theory in music education, shows the considerable effect of numerous intelligences teaching strategies in enhancing students’ intelligence, and provides new methods and perspectives for music teaching.
