To start building up their confidence with the piano, play the keyboard with your child and gently show them how to push the keys as they light up. Once you’re familiar with the tune you can help steer their fingers to the keys when they light up. Gradually let them do more of the playing on their own, until they’re able to follow the entire melody unaided. This will do wonders for their hand-eye coordination, as well as their sense of accomplishment.
