Why do songs get stuck in our heads? Explaining Earworms | Science of Sound
The lesson explores the phenomenon of “earworms,” or songs that get stuck in our heads, through insights from neuroscientist Dr. Carol Sherling. It explains that earworms result from involuntary musical imagery, where the brain continues to process music even when it’s not playing, influenced by factors such as catchy lyrics, emotional resonance, and repetition. Strategies to manage earworms include replacing the song with another tune, discussing it, or even chewing gum to distract the brain.
