As an advanced presentation form of digital teaching, blended teaching integrates the dual advantages of traditional teaching and network teaching, greatly extending the spatial dimension of teaching, revitalizing teaching resources, and enriching teaching means in education and teaching reform. This paper carries out in-depth research on the modules of teaching resources sharing, teaching interaction and skills training under the hybrid music education teaching mode. And by optimizing the Flanders interactive coding system, it compares the interaction of students under the conventional teaching mode and the blended teaching mode. Matrix analysis and classroom structure analysis were used to analyze the classroom teaching performance of the sample classroom in terms of teacher-student language structure, student participation characteristics, and so on. Through comparison, it is found that the blended teaching mode is able to realize deep interaction in the classroom, with greater improvement in student participation and more in-depth and efficient interactions between teachers and students, and between students and students.
