Nope, my parents bought me a piano down the auctions when I was about 7 and I could play anything I heard on telly by ear, so I went to lessons when I was about 8 but its quite daunting when you are young and getting graded. I remember being so nervous before my grade 5 that I honestly though about smashing my hand up.
With the guitar thats just by ear too. I think I would have been quite good if I had been young when I picked it up.
I have a friend who is a session musician and he can play anythng . I have limited improvisation skills to be honest, if i could be anything it would be a rock star but Im just not cut from that cloth.
