The short answer is no. Children may develop differently and, therefore, there is no perfect age for starting to play the piano. There are cases of 3-year-old children who are already quite skilled at exploring the sonic realms of a musical instrument yet such cases are rare.
To make sure that your kid is ready to embark on such a journey, there are some things you might want to consider before signing up for piano lessons. Your child’s hand should be developed enough to handle a keyboard comfortably and properly. This means that your child should have no problem placing the fingers of a hand on five adjacent white keys.
The child should be able to move individual fingers with ease and enjoy good finger independence before starting piano lessons. You can help your little ones with that by engaging them in various exercises that involve practicing finger independence.
Keep an eye on your child’s interests. If your little one shows an interest in music and playing a musical instrument, then you might want to try a few piano lessons to see how your child responds. Most children are ready to play the piano between 5 and 8 years of age yet there are exceptions to the rule.
