At what age should i start my little girl in piano lesson? She already show some interest, she is 19 months old and can sit for a hour or more at our family piano and play with the keys. she will also sit and strum on a guitar for a bit too, but she show much more interest in the piano. She has been siting on the bench or with me playing with the keys since she was a year or less.
Some tutors do teach children from 18 months, however, it generally isn't recommended.
Most tutors prefer to teach once the child is 4 years old, by that point, the child has a basic idea of rhythm.
Sounds like she'll be a little musical genius though! I recommend you start her on piano lessons a few weeks before she goes to primary school and then see how she copes with piano playing and doing homework from school at the same time.
