Pop music hit maker Clive Davis knows a catchy song when he hears one. Now an app aims to define that elusive quality more concretely.
Designed by computer and cognitive scientists at the University of Amsterdam and Utrecht University in the Netherlands, Hooked! asks citizen scientists to help uncover the mystery ingredients of a hook — the most memorable part of a song. The results might illuminate how music taps into memories and emotions in the brain. First the app drops the needle somewhere in the middle of one of the 2,000 most popular songs of all time. Listeners quickly report whether they know the tune or not. To test whether the listener really does know the song, the app then turns off the music.
