Earworm.
What Is an Earworm?
An earworm is a piece of music that repeats involuntarily in a listener’s mind long after the music has stopped, a phenomenon psychologists call involuntary musical imagery. Typically a short, simple, repetitive fragment of melody, the earworm is the effect every advertising jingle is engineered to achieve.
Earworm in Practice
The term translates the German Ohrwurm and entered mainstream research through marketing professor James Kellaris of the University of Cincinnati, whose studies in the early 2000s found that nearly everyone experiences stuck songs, with simple, repetitive tunes the most likely triggers. Kellaris’s surveys repeatedly ranked Kit Kat’s ‘Gimme a Break’ jingle among the stickiest earworms ever tested, proof that a well built advertising melody can lodge a brand in memory for decades. For sonic branding, the lesson is double edged: repetition and simplicity buy recall, but an earworm that irritates can attach the wrong emotion to a brand, so craft and restraint matter as much as catchiness.
