“Whenever a noise exceeds our processing abilities—we can’t
decipher all the different sound waves hitting our hair cells—
the mind . . . stops trying to understand the individual notes
and seeks instead to understand the relationships between the
notes. The human auditory cortex pulls off this feat by using
it's short- term memory for sound (in the left posterior hemisphere) to uncover patterns at the large level of the phrase,
motif, and movement. This new approximation lets us extract order from all those notes haphazardly ͒flying through
space, and the brain is obsessed with order . . .
It is this psychological instinct—this desperate neuronal
search for a pattern, any pattern, that is the source of music . . . We continually abstract on our own inputs, inventing
patterns in order to keep pace with the onrush of noise. And
once the brain ͒finds a pattern, it immediately starts to make
predictions . . . It projects imaginary order into the future . . .
The structure of music reflects the human brain’s penchant for patterns . . . But before a pattern can be desired by
the brain, that pattern must play hard to get”
