The structure of piano is different from accordion and electronic organ. The keys of the accordion and electronic organ belong to the touch mode, and the sound can be made by pressing the finger lightly, while the piano needs about 30 grams of strength for each sound (the bass area needs more strength). If the child is too elementary to play the piano, he can't meet this strength requirement, not only can he not learn the piano well, but it will also damage the normal development of his fingers after a long time. By the age of 5, children's cortical cells have been roughly differentiated, the central nervous system is more mature, and muscle development is more perfect, which provides good physiological conditions for learning piano.

During the age of 5-6, children usually spend their time in a relaxed and happy kindergarten. There is no heavy homework in kindergarten during this time, so I have enough time to practice the piano when I get home. Learning piano is very difficult and boring for beginners. You should not only read the music score, but also pay attention to the teacher's requirements. If this difficult and boring beginner stage is put in the primary school stage, it will cause psychological pressure to the children because of the heavy burden. Over time, it will be polarized, or tired of learning, or afraid of learning the piano. 1-2 years of study, so that children have a certain interest in the piano, with a certain foundation. At this time, even with the tense rhythm of school life, the focus of children's learning will not shift. On the contrary, playing a relaxed and happy ditty can also adjust the tense learning atmosphere in school.
