There is a vast array of music teaching resources on the Internet, and how to effectively access them through search engines requires some effective search methods. This article focuses on the impact of Boolean logic optimization on the effectiveness of music teaching. The article first discusses the Boolean model under the information retrieval model and discusses the specific operations of Boolean logic in detail. It then further optimizes and improves the traditional Boolean logic binary tree algorithm. The article finally tests the search rate and accuracy of the Boolean logic optimisation model proposed in this paper and validates the effect of the Boolean logic optimisation model proposed in this paper in music teaching by taking the students of a school as the empirical research object. After optimising the Boolean logic of music teaching content, in the analysis of the aesthetic perception dimension, about 95% of the students thought that they had been able to feel the emotions expressed by the author through feeling the music and also agreed that the use of the Boolean logic model in music class had the effect of improving music literacy. Thus, the Boolean logic optimisation method proposed in this paper has a positive effect on music teaching.
