The song has stopped. The chorus has not.
An earworm is a tune that comes to mind and repeats without you deliberately recalling it. Researchers call it involuntary musical imagery.
You have finished the washing-up. The kitchen is quiet. Your mind, apparently, has booked the chorus for an encore.
Why that tune?
Recent listening and familiar associations can bring music back to mind. A phrase, place or situation may remind you of a song without any speaker being switched on.
That helps explain the uninvited replay, but not why one particular tune keeps winning. Researchers have also looked at the music itself.
Familiar shape, surprising little twist
In research published online in 2016, Kelly Jakubowski and colleagues used songs named by 3,000 survey respondents. They compared 100 frequently reported earworm tunes with 100 songs matched for popularity and style.
The earworm group tended to have faster tempos, familiar overall melodic shapes and less usual patterns between changes in melodic direction. Recent chart success also mattered. The APA’s explanation describes that mix of familiarity and surprise.
Catchy is not a magic formula
These are patterns across songs and listeners, not a recipe that guarantees a hit. Personal associations and what you have heard lately still matter.
