The first thing every training teacher should do is to understand and master the basic skills of guitar and solfeggio. He should know what the most important guitar skills are, what the most important foundation is for learning music, and how to let students master the basic skills step by step and learn music by playing guitar. The best form of learning is to practice in pairs. One person plays the main theme of music, and the other plays harmony accompaniment or polyphony. When students' skills have not reached a certain level, don't buckle those difficult songs, which will only destroy the musicians' works, never play perfectly and never learn any music. . . . There are very big problems in guitar learning. Nobody wants to learn solfeggio by playing the guitar. . . Your goal is too high, and you will die without any basic skills. . . Inferiority, no skill and sense of music, but conceited. . . 4 Do not pay attention to other musical instruments and solfeggio. In fact, strings, wind music and keyboards are more suitable for learning music. Many guitar teachers are misled by others. In their teaching, they didn't learn any useful music knowledge, just stuck to the 6-line score and played some tricks.
