My 5 year old has been playing now for 1 year and is really enjoying it.
As an adult that was forced to play (another instrument) throughout his childhood… Who is grateful today for having learned music, though it was a struggle for both sides growing up.
I think it’s super important to encourage your child to learn not through regimented lessons. Find what motivates them, whether the challenge, music they like, or leading by example.
I’m not suggesting this, but we purchased a new 6’3″ Baldwin Grand piano. I love the thing to death.
That was important as playing on a fine instrument is my motivation. So I’m learning the piano along with my child. My wife played as a child as is getting back into the grove.
My child is really enjoying the experience as she is motivated by our mutual love for music and the piano.
