I strongly recommend piano for young children starting around the age of 5. I believe you can build a strong foundation for their musical development by starting with the piano. I began playing the piano at the age of 5 and it has helped me tremendously with learning other instruments. Because the keys are big and a child’s fingers are small, it does not require a great deal of fine motor movements of the hands, like some other instruments. As a child grows, their coordination will build along with their ability to learn the instruments that will require more. Furthermore, learning to read music and acquire theoretical knowledge on the piano can be an easier task. It’s also a wonderful instrument to sing along to and eventually write your own music with.
