Why Do We Get Musical Earworms?

Imagine your brain is a music box that keeps spinning even after you stop winding it. Sometimes, a tiny piece of a song gets caught in the gears and plays over and over until you notice. This happens to almost everyone! It usually starts with something simple, like a catchy rhythm or a word you just heard.

Your brain loves patterns. When it hears a tune, it tries to complete the pattern. If the song stops right when your brain is expecting more, it keeps playing that part internally to 'fix' the gap. Think of it like a cognitive itch you can't scratch without humming along.

• Hearing a song on the radio and remembering a happy memory
• Learning a new rhyme at school
• Feeling stressed or bored, which makes your brain search for familiar sounds
