Why Ear-worms Get Stuck in Your Head

We all get a sensation when a song, for no apparent reason, refuses to leave your head — in fact we’re no strangers to the dreaded “ear-worm.” But a new study published in Psychology of Aesthetics, Creativity and the Arts reveals a fascinating insight into ear-worms, and why some songs are better than others in sticking in our heads by investigating the actual elements of the song that make it catchy in the first place.

To do this, most frequent ear-worms of the participants were entered into a database and compared to songs that had never been reported as an ear-worm at all. The melodic features of the tunes were then analyzed, revealing that ear-worm tunes were typically those songs that have overall melodic shapes common in Western pop music. A classic example of a common contour (音调的升降曲线) pattern is heard in Twinkle, Twinkle Little Star, where the first phrase rises in pitch and the second falls. This makes the tune easy to remember and has been exploited in many other nursery rhymes, but also in pop music.

In addition to the melodic shape, the other ingredient to the ear-worm formula is the unusual interval structure. The aim of this is to surpass the listener’s expectations of an average pop song, showing unexpected leaps or more repeated notes than usual. “Our findings show that you can, to some extent, predict which songs are going to get stuck in people’s heads based on the song’s melodic content,” says one of the researchers, “This could help song-writers or advertisers write a jingle (短歌) everyone will remember for days or months afterwards.”

The authors conclude that studies of ear-worms can help explain how the brain works, and improve our understanding in how perception, emotions, memory and spontaneous thoughts behave in different people.
