I get asked this question all the time .
I have to say it’s completely individual . I have taught lessons to 5 year olds who can have a one hour lesson and then 9 year olds who can barely finish a 30 minute lesson . I always ask the parent to just really think about their child’s concentration level & how long can they actually spend learning something new – try something at home first, like trying to learn about a new toy and see how long it is before they get bored, frustrated or tired.
At Key Lessons we have had 2.5 year old learning the piano so it really is an individual thing!
Any questions do not hesitate to ask !
