Comment by haraan kazim on For the Musical Genius - Chapter 33

@haraan kazim I think it's because it's art that the question is asked. He's expressing himself artistically when he plays, so self-understanding probably contributes to his expression. On the other hand, maybe it's all mechanics and skill in reality they could be thinking of something totally mundane while playing.

It's a matter of whether you consider music a matter of craftmanship/skill or an emotionally driven art thing I guess.

@haraan kazim That's the right way of thinking. To not be constrained by reasons and play to your hearts content!! 
The reason why they ask is to know if you want to play music to gain fame, money and just show off. Or their is a goal to be the best in it. 
Those who give these kind of reason will probably not achieve the pinnacle for, once again, art shouldn't be constrained by reasons but Passion!!
