@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.
