I think someone should explain to the child that it's OK to make mistakes. That's how we learn. When we compete, we make mistakes.
My father died when I was 4 years old, so I can't really say anything about his hearing.
What I'm making music for now is more similar to what I was doing in the beginning. In those days it was all about doing music so when people heard it in a club it would take their minds of their worries. I got more artistic but now I've gone back to basics.
