As a musician and a developer, I can agree with most of this. I do however, see it as two opposite sides of a defined spectrum. When I am playing an instrument, I typically lose any connection with thought or the rest of my body not directly involved in playing. My mouth sorta drops down and I begin to almost drool. Something my girlfriend loves to remind me of. I am literally lost in the music. When coding, I am almost hyper aware of the thought process. I am surely focused on only what is happening relating to the code, but the disconnect from myself never happens. I think the connection is the desire to create something and an inborn understanding of modularity and the flow of ideas/actions. People with these qualities are often drawn to both.
