There is a detailed introduction in the CD of the author of "Learning Piano Most Afraid of detours", and the author has also explained this problem through tutoring parents of piano children.

Children must not tap the potential of their ears, so they are not interested. If you don't understand this truth, learning the piano will be as difficult as sending the deaf to learn to speak and read, because music is another way to speak and read.

Do you understand the above reasons? In fact, if your child doesn't want to take the initiative to find a teacher, you can skip the piano class first. Now parents are training to listen to single notes at home and then give them more beautiful piano music. Subtle is the first thing to do. It will be very effective to learn the golden music language before the child is 4 years old, and the potential development will be ignored when learning knowledge and practicing fingers. Putting the cart before the horse is a detour.
