From After Dark by Haruki Murakami. It’s a strange little novel that consists mostly of conversations at night. The first line is from a 19-year-old girl talking to a jazz musician:

“What do you mean, ‘playing really creatively’? Can you give me a concrete example?”

“Hmm, let’s see… You send the music deep enough into your heart so that it makes your body undergo a kind of physical shift, and simultaneously the listener’s body also undergoes the same kind of physical shift. It’s giving birth to that kind of shared state. Probably.”
