When my opera Plump Jack was performed in 1989, my first piano teacher sent me something that I'd composed when I was four. I remember I played it, and it still sounded like me. I'm the same composer I was then.
If you lock me in the room with a piano teacher for a year I might be able to knock out a rendition of 'Roll Out The Barrel,' but will I ever be a concert pianist? No.
I'm blessed with a good pair of ears. That's how I fooled my piano teacher. I'd watch his fingers and I'd listen to it, and I just kind of basically learned it by myself.
