I play piano and have since I was 7 I believe... I stopped taking lessons years ago though, and have just been teaching myself songs. I never really liked lessons... it was too strict a regime for me and I liked to play on my own time, with my own selection of music.
My favourite pieces to play are mostly Elton John. His songs are beautifully written, and so fun to play!
Just this past xmas I got a guitar, so I'm slowly teaching myself how to play that too.
