The Effects of Music on the Brain
Music listening, performance, and composition engage nearly every area of the brain that we have so far identified, and involve nearly every neural subsystem.

Brain Activity Copies Music Frequency
If I put electrodes in your visual cortex (the part of the brain at the back of the head, concerned with seeing), and I then showed you a red tomato, there is no group of neurons that will cause my electrodes to turn red. But if I put electrodes in your auditory cortex and play a pure tone in your ears at 440 Hz, there are neurons in your auditory cortex that will fire at precisely that frequency, causing the electrode to emit electrical activity at 440 Hz—for pitch, what goes into the ear comes out of the brain!
