Healthy earworms

A catchy tune that runs continually through your mind, known as an earworm, can be very annoying, but Neville Roberts has found they can also have beneficial effects

I don't know about you, but it doesn't take much for a tune that I like to become imbedded in my brain, especially if it's new. These so-called 'earworms' keep playing in your head over and over again, particularly when you find yourself in a quiet environment. They can often feature at the start of a piece of music and are simple in structure. 

An earworm is a psychological phenomenon where a musical figure keeps playing in the mind long after the listening experience is over. In popular music it comes most often from the vocal melody, but can actually appear in any musical shape or form. Many earworms come from song hooks, but not all hooks become earworms.
