INTRODUCTION I.
With the development of society informatization, the computer has been widely applied in the daily teaching and has become the indispensable modern teaching infrastructure and technical support environment. The teaching management system can significantly improve the students and the teachers in the information sharing and the quality of teaching. For a music teacher, the music teaching management system includes the teachers' personal information, the teaching information query, the teaching file management and the teachers' evaluation of the students and the course [1][2].
In the 21st century, the whole of human society is developing human understanding for the way of perception at an alarming rate changes with the development of technology and culture. People are trying to rely on computer networks and the existence of virtual reality technology to expand into more of the space environment and enjoy the colorful visual feast of the virtual world. Virtual reality technology is an immersive interactive technology which is based on computer technology and data processing technology. It creates a real-time interactive threedimensional space. From virtual reality users can operate and apperceive all of the various objects in the virtual world and make access to the space and logical information implied among the virtual environment.
The virtual reality is the computer simulation three dimensional environments, is one kind may found and experience the hypothesized world the computer system. It through human's vision, sense of hearing, touching, tasting and smelling function in the user, causes the human produces experiences personally ground view simulation. Because of the hypothesized technology produces hypothesized artistic atmosphere, space and environment by using the computer, not only may the reality but also the unreality be object, direct-viewing. This can differ the reality and the unreality, and has broken down the strict boundary between both. It will be the real-time communication, have the sound-surround ambiance. The applica-tion of Virtual reality, which causes the music teaching, the demonstration, the creating and the sharing and so on to be more scientific, effective, appropriative. It also conforms to the characteristic and the request of the current information age. Its goal is to use formidable computing power and graph exaggeration ability of computer, and make hypothesized world which seems real sufficiently.
Due to the poor interaction of traditional music teaching method, the efficiency of the usage of music teaching resources is low. In order to solve the problem, visual reality thinking should be used to reform the traditional music teaching method.
Having been developed for more than 20 years, the technique of virtual reality (VR) has become one of the most important and inventive 21th century technologies, paralleling with internet and multi-media. VR is a type of synthetic integration technique, which integrates computer graphics, computer human interaction, sensor technique, artificial intelligence, robotique, etc. and features with multi-sensing, immersion, interactivity and imaginary, etc. Therefore, we can use the virtual reality technology to solve the problem of low cross mutual inductance and low efficiency in tradition music teaching.

Ministry of education on the education facing the 21sl century revitalization action plan [3][4][5], the article has made clear that are widely used in the modern information technology in education leads to profound changes in the education system. In terms of vocal music education field, the category of longitudinal fine development and integration with other subjects is an important trend of the development of the contemporary vocal music, increasing its total knowledge information geometric type [6][7]. Reflected in the vocal music discipline, mainly to enrich the song theory, a new mechanism and singing techniques and style of the deepening of the study, with the integration of related subjects and infiltration is increasingly strengthened. This shows that it is very necessary to apply virtual reality technology to music teaching system. This is also the need of the development of the times [8].
With the development of social productive forces and science and technology, VR technology is growing demand in all kinds of fields.The research of virtual reality and VR software is of vital importance day by day. Virtual Reality is a new research paradigm in psychology research area; it has some characteristics such as multi-perception, immersive and interaction. In recent years, with the devel-PAPER APPLICATION OF VIRTUAL REALITY IN MUSIC TEACHING SYSTEM opment of network and multimedia technology, the comprehensive technology, virtual reality (VR), is being increasingly applied to all walks of life, providing more multi-dimensional information display. With its rapid development, more applications in many fields have made a breakthrough progress, such as city planning, industrial simulation, virtual studio, medicine, education, aerospace, entertainment, art etc. [9][10]. Research on virtual reality technology in the field of education has become more and more mature, especially in language learning, learning environment construction and simulation campus' application and implementation. Virtual reality solves the problem that perception and action separating, leads the perception and action study more natural, improves the study ecological validity, and holds great promise for the study of perception-action. In decades, researches about the relationship between perception and action in baseball, handball and tennis found that, athletes can make exact interceptive actions in virtual environment [11]. Figure 1 shows an instrument playing system based on the visual reality technology. And Figure 2 shows the a student learning by the system. METHOD AND ALGORITHM III.
