Singing is the basis of learning music and the best way to get a good music quality education. In primary school music education, singing teaching is one of the main contents of music teaching, and it is also the most acceptable and willing form of music expression for students. The requirement of students' singing teaching in Music Curriculum Standard is "to inspire students to sing with emotion, with emotion and sound, and attach importance to strengthening chorus teaching, so that students can feel the rich expressive force of multi-part music and their self-confidence in singing, so that they can enjoy the pleasure of beauty in singing performance and be influenced by beauty ..." First, to cultivate self-confidence and emotional singing, voice skills are of course very important, but for primary school students, the key lies in cultivating them. 1. It is the teacher who vividly sings in teaching, conveys the information of songs, makes students truly experience and feel the beauty of songs, and makes students know songs as a whole. Teachers' exemplary singing can directly affect whether students like the songs they have learned. Therefore, teachers ask students to sing good songs, and they must sing well first. If the teacher is first moved by the song, and sings the song with devotion and emotion, the song will certainly make the teachers and students have a spiritual sound, produce spiritual communication, have a positive effect on the students, make the students have a strong interest in song learning and stimulate their strong desire to learn songs. 2. Learn to understand, analyze and handle any song work. Its characteristics and musical style are achieved through the use of musical elements (rhythm, speed, dynamics, timbre, etc.). In the teaching of singing, the deeper and more comprehensive the students understand the song, the better and more touching it will be. In teaching, we should teach students to have a preliminary perception of the musical image of songs, guide them to analyze the feelings, structure and climax of songs, and learn to express their feelings by controlling the strength, speed and timbre of sounds. Second, carry out the necessary basic singing skills training. The basic singing skills training for primary school students is different from professional vocal music training, but regardless of the depth of training and the level of requirements, it must be based on scientific training methods. In our regular classroom teaching, we should not only psychologically guide students to sing with confidence and passion, but also pay attention to giving them the necessary singing skills. 1, to cultivate students to establish a correct concept of singing, to develop good singing habits. Guide students to sing with good singing posture. When singing, the body should be natural and upright, the waist should be straight, the eyes should be straight, the head and neck should not lean forward or backward, and the neck should not be oppressed, so as to ensure the free movement of the diaphragm. Make students master the correct breathing method-chest-abdomen combined breathing. In teaching, vivid metaphors such as smelling flowers, jumping rubber bands, sobbing, coughing, yawning and shouting across the river are used to help students understand. Gradually correct the problems in students' breathing methods. Combined with the age characteristics of students, the lower grades of primary school focus on expanding the range of students, and in the middle and high grades, the method of training the head voice is mainly used to make its voice round, clear and sweet, which is conducive to the performance of music and increase students' interest in singing. Teach students to pronounce words clearly. Singing is the art of combining music with language. It is necessary to express the meaning of words accurately and clearly, rely on correct articulation, and integrate natural and mellow pronunciation with the correct pronunciation of lyrics. Through reading aloud, teacher's demonstration, students' imitation and comparison, etc. Enable students to "clear the initial consonant, lead a long belly and stop the ending", and gradually achieve clear pronunciation and mellow voice and sincere feelings. 2. Find and correct the wrong singing methods in time. Shout the question. The main reason is that students want to express themselves to attract others' attention and the pronunciation method is incorrect. Make them understand that beautiful singing is a voice from the heart, and it is a manifestation of inner feelings with appropriate volume and sincere feelings according to the emotions and needs of songs. In teaching, we should guide students to adjust their breathing, naturally open their mouths and relax their mandibles, and teach them the methods to control and adjust the volume, find it at any time and correct it in time. In the process of voice training and standardization, we should combine the reality, adopt scientific methods, overcome it purposefully and in a planned way, and at the same time, we should teach students the method of self-adjustment.
