With the rapid development of computer technology, multimedia technology has penetrated all levels of society and is widely used in music education. In order to make better use of multimedia for teaching, teachers are actively learning about multimedia computer knowledge and exploring the use of multimedia for teaching, but some institutions have not yet established multimedia music classrooms due to the limitations of funds and classrooms. With the improvement of educational conditions, multimedia music teaching systems should be set up in schools as soon as possible, using multimedia technology for music teaching-learning, which can be used for teaching music theory classes and some music skills training. In primary and secondary schools, multimedia can clearly demonstrate the content of the music curriculum and can be used to teach students in an intuitive way, increasing their interest in the lessons in a short time. In university music teaching, multimedia music teaching can improve the efficiency of students' learning and get rid of teachers' indoctrination learning method.
