In this article, we will try to explain the inexplicable: because there are several strange phenomena that do have a scientific clarification. Which?
Known as an earworm, it’s a phenomenon most of people have experienced. What causes it? There is a lot we don’t know about, but one contributing factor is simply hearing a song repeatedly in a short amount of time. One study found out that songs with certain structure (smaller pitch intervals, repetitive patterns) tend to get stuck. Other researches affirm that the size and the shape of your brain might play a part.
PS. A study from the University of Durham affirm that songs that get stuck in your head are usually faster, with a fairly generic and easy-to-remember melody but with some unique intervals such as leaps or repetitions that set it apart from the “average pop song”. Prime examples of earworms named in the study include Bad Romance by Lady Gaga, Don’t Stop Believing by Journey and perhaps not surprisingly Can’t Get You Out Of My Head by Kylie Minogue.
The surprise stems from the mechanics of your ear. When you speak, you hear your voice in addition to vibration from your vocal cords passing through your throat and mouth into your inner ears. These vibrations are typically low frequency, which is what you are used to hearing. On a recording instead, you only hear the air conducted sound, which is why you might think you sound higher pitched.
Listen to music you like release dopamine, and the brain could give it a kick: it anticipate the release, thanks to particularly intense moment in a song or a melody. Researches affirm that two third of the world population can feels chills!
