Remember scrolling through the radio dial, hoping a tune you liked would pop out of the static? You never had to listen too long to know you'd landed on a hit.
"Music has a really strong, remarkably strong, hold on us. So it's way enough to be exposed to a very brief snippet of a familiar song for us to be able to recognize it."
Maria Chait, an auditory cognitive neuroscientist at University College London.
Chait and her team recently studied how quick that reflex is. They started by asking 10 volunteers to name a feel-good, familiar song—like this:
(CLIP: Song 1)
Then the researchers handpicked a second tune that sounded similar but was unfamiliar to the volunteer.
(CLIP: Song 2)
They chopped both songs into tiny bits—each less than a second long—and then randomly interspersed them into a six-and-a-half-minute-long track of song snippets.
