korvakoruun

Korvakoruun is a term of Finnish origin that translates roughly to "earworm" or "stuck song." It refers to a catchy or repetitive piece of music that becomes lodged in a person's mind, playing on repeat involuntarily. This phenomenon is a common auditory illusion experienced by many people across different cultures.

The precise psychological mechanisms behind korvakoruun are not fully understood, but several theories exist. One prominent explanation suggests that incomplete musical memories or patterns trigger a self-sustaining neural loop. The brain attempts to "complete" the melody or a recurring motif, leading to its persistent playback. Factors such as the song's structure, its repetition, and its emotional resonance can contribute to its likelihood of becoming a korvakoruun.

Korvakoruun can be triggered by various stimuli, including hearing a song on the radio, in a commercial, or even just thinking about it. While often considered a minor annoyance, some individuals may find prolonged or intense experiences of korvakoruun to be distracting or even bothersome. There is no known cure, but strategies like listening to a different song, engaging in a mentally demanding task, or humming the tune until it fades are sometimes suggested to alleviate the effect. The phenomenon is generally considered harmless and a normal aspect of human cognition.
