My 6 year old was praised last lesson for picking up the piano so quickly. The teacher thinks he has a little talent. He practices of his own free will for 10-15 minutes every day. Good for one so young I should think.
The community center cancelled the group lessons, but he asked if he could take lessons at the music school instead. He had his first lesson with his Squier Strat and did OK.
Last night I came to check on them before turning in, they had snuck one of my CDs upstairs. I found them asleep on the floor listening to the Help! album on repeat. It gave me a flash back to when I was a kid sneaking my transistor radio into bed.
