He's smart, yes. Extremely, even.
But, I think the author wants to portrays how his talent in music came from who he is, and how smart and witty his personality came from his hard work and experience.
Because he's not trained in music.
frightening how smart and clever he is, its like his frontal lobe developed since he was out of the womb in this life if you were to look at it from an outsiders perspective
That's what I was saying. like how does this to other people, he's just a monstrous genius to them ?
ohh that makes sense
He's not just a musical genius bruh. he's just a genius
