The best age should be around four years old. His innocence and sensitivity to music is a particularly good time for children of this age. His hearing and sensitivity to music are good, and this time period is more suitable. Children learning double-row keys will naturally have some advantages that adults don't have.

1, musical sense

Learning double-row keys from an early age is mainly conducive to the cultivation of musical sense. Everyone who studies music knows how important the sense of music is to those who study musical instruments. 3-7 years old is the golden age of music enlightenment, and this time is the best time to practice your ears and hearing. If you don't learn from an early age, it will be difficult to cultivate a sense of music when you are old.

2. Music literacy

The most useful thing I learned from the double-row keys when I was a child is definitely not the playing skills, but the language of the whole music. For example, if you play the piano in primary school, what you learned is the piano playing method. But by learning double-row keys, I learned the timbre of all instruments and various styles of music.

3. Fingers

Generally speaking, young students learning the piano is more conducive to training the flexibility of fingers, the flexibility and softness of wrists, and the coordination between the whole body and playing movements. Moreover, double-row keys are not as hard as piano keys and will not hurt children's finger joints.

4. Plasticity

When I was a child, I had a strong learning ability. The development of my hands, brain and hearing was like a blank sheet of paper, and my plasticity would be strong. In addition, practicing piano takes up a lot of time, so children will have more time without life pressure. If you learn when you grow up, it will be difficult for ordinary people to stick to the practice time every day because they can't guarantee it, so generally speaking, learning piano begins at an early age.

If you have a keyboard foundation, you will naturally learn more. If you have learned the piano before, and then learned the double-row keys, the biggest difficulty is to add hands and feet.

Sometimes you have to use both feet, that is, you have to "dance" with both hands and feet. It is difficult for beginners to adapt, but after learning for a while, the problems can be overcome after proficiency.
