Finally, there is something to say about music that is more than just the psychoacoustics of pitch or timbre. It's been a while since neuroscience has probed music. This article not the grand unified theory of the neurophysiology of music, but it's a start! The scientist in me welcomes the decomposition of the human condition into definitive details that explain how we appreciate music, or for that matter, any art.
