Dissonance and Evil
So, my three-year-old and I were listening to Pink Floyd's Atom Heart Mother in my car and at a particularly dissonant section she said, "Daddy, this sounds like my God book."
So, of course I had to ask about that. Turns out that it sounds like the snake in the garden to her. The very naughty snake.
No theological point here, rather a perceptual psychology observation. Apparently, by nearly four years old, dissonance sounds evil, without words or other cues as to what the song means.
