It is not enough to improve the quality of first-line music teachers only through short-term training. As a music teacher, the importance of professional quality. We should regard improving quality as a daily job. First, we should have comprehensive music professional skills, such as singing, playing, acting and showing in teaching activities, which can give students an immersive experience, thus stimulating students' interest in learning and meeting their aesthetic requirements. This requires me to keep practicing in my own music major. Second, mastering multimedia teaching With the rapid development of science and technology, electronic technology has been rapidly applied to music art, especially after the appearance of computer music, the use of some computer software can enable us to make music with any tone, volume and duration on the computer, and the music made by the computer has high accuracy and is convenient to modify. As far as communication channels are concerned, music can break through geographical and national boundaries through computers and electronic information. Therefore, music teachers should change the traditional teaching methods, widely use multimedia and electronic information tools, and organically combine multimedia, electronic information technology with traditional music to achieve results! Third, teachers and students interact, communicate more, listen to students' opinions and absorb them widely. In the process of communicating with students, we all have a feeling that some of our habits and languages can't keep up with students. Students often say: Teacher, you are too kind. So I think in this respect, we should listen to students' voices more. We should also know something about what they are interested in, but we should not be ignorant. Otherwise, it will widen the generation gap, make it difficult to communicate with students and have a good class. Therefore, I think that understanding students' lives is also a long-term homework that teachers should do. Fourth, always specialize in research, keep learning, keep pace with the times and enrich knowledge. In the information age where knowledge is updated so rapidly, we must establish the concept of lifelong learning, otherwise we will fall behind the times. Cultural literacy and professional skills can not be ignored. Cultural knowledge is closely related to music teaching. With profound cultural literacy, we can have a deeper understanding of music, express the connotation of music more accurately, and let students get twice the result with half the effort. And the improvement of professional skills can not be ignored. In other aspects of artistic accomplishment, we should also be familiar with sister arts such as art, film and television, and poetry.
