Positive psychology plays a very important role in children’s music education. The growth of children is first the growth of mental body rather than the growth of discipline ability. Positive psychology holds that children’s music education should actively provide the environment for children to experience the joy of success, turn failure into a positive factor, recognize the value of performance, and avoid boring and long term music learning. Children’s music teaching should focus on encouragement, pay attention to children’s happy experience, strengthen cooperation, advocate “learning in playing and doing, pay attention to comprehensive ability, and give play to children’s independence.
