An earworm is a tune or a song that gets stuck in your head that you just can’t get rid of. It hangs around, sometimes for days. It can be a commercial jingle (they’re the worst) or something silly like The Muppets’ “Ma-na Ma-na” song.
Sing your song to yourself enough that it becomes an earworm and gets stuck in your head. Just make sure you sing it right though – if your earworm learns the wrong tune it’s very hard to change its mind!
When you find yourself walking down the street or washing dishes or getting ready for bed and humming and snapping your fingers to “Georgy Girl” or waltzing about to “Shall We Dance” – you’ve got an earworm!
