DS1 is 4.8 and has said that he wants to play the piano. I think he might be a bit young for formal lessons, he's a September baby so not at school yet. He sings very well and we have a piano (I got to about grade 6/7) and I'd like to teach him without it becoming to much of a serious kind of thing. I want him to learn in a fun sort of way, learning things by ear to start with and not too much boring or methodical stuff (I know he will have to do this at some point, but I had issues with a teacher who was obsessed with grade exams and theory exams when I just wanted to play the thing!). I don't really know where to start. Any tips/ experiences please!
