I am quite proficient in playing the piano as I have learnt it since I was about 4. xD That's not all, though! I can also play the violin, the guitar and drums, but I'm not very good at them.
I used to take violin lessons up to Grade 4, but I stopped. Don't remember the reason why. Now my skills have turned all rusty ;_; I still know how to play it, but not as well as I used to.
As for guitar, I kinda self-learnt. One day, a guy brought a guitar to class during high school. He played a few chords to a song, and I asked if I could try. It all started from there. xD
My previous school made instrument classes compulsory, and drum classes was one of the choices. I took drums. Loved it! xD
