We’ve all had it happen: One song finds its way into your brain, and try as you might, you can’t make it go away. Oliver Sacks calls the tunes “earworms,” and they have been known to stick in people’s minds continuously for weeks at a time before finally dying out.
They can be maddening. I can still remember several earworms dating back to my childhood:
- At the age of 11, Cheap Trick’s “The Dream Police” kept me up for several nights with the same ironic line repeating over and over: “The dream police, they live inside of my head…” I have avoided it ever since for fear that the worm would work its way back into my brain. Sacks says this is normal; after an episode, there is a heightened sensitivity to that song, so that even years later, a reference to the song or a snippet played on the radio can retrigger the earworm.
- Even more ironic, ELO’s “Can’t Get It Out of My Head” could not get out of my head one day, the first line of the chorus replaying itself until I thought I would scream. I think Jeff Lynne had the same idea when he wrote the song.
- About 10 years ago, The Push Stars’ “Wild Irish Rose” played over and over in my head after I listened to it on a plane trip to Portland, Ore. Twenty years later, I still can’t listen to it.
- Just this morning, I woke up with the chorus to Whodini’s “The Freaks Come Out At Night” (Yes! A rap song!) in my head. Why? I have no clue. I can honestly say I haven’t heard that song in 25 years.
Even Neil Diamond is susceptible, according to the San Francisco Chronicle. “If I wasn’t in the business of songwriting, I’d probably be seeing a doctor,” he said. “I’ve tried everything from cold showers to listening to other people’s music, but nothing helps.”
Many times, just a snippet of a song will get stuck in my head, and it closes itself into a loop, trying to find a way out. Frustrated, I sometimes have to play the whole song in my head to show the earworm how to get out of the loop. (It reminds me of a “M*A*S*H*” episode in which Father Mulcahy is playing a song on the piano. When someone asks him what it is, he says, “I’m not sure, but whatever it is I can’t seem to find the end. I’ve been playing the same thing for 20 minutes.”)
The same thing happened to Mozart. When he was a child, his kids would drive him crazy by playing songs on the piano and then stopping them. His brain would force him to go downstairs and complete the song because his ears couldn’t resolve what his brain was hearing.
Causes of Earworms
Sacks attributes this phenomenon, which counts even Mark Twain as a victim, to two causes:
- Western music’s emphasis on patterns — verse, verse, chorus, phrases repeated over and over – are meant to be consumed and to stick with you. This “stickiness” can separate a hit from the thousands of songs that are released each year. Unfortunately, it can stick too much.
- Music is ubiquitous nowadays, making the problem worse. With the iPod, we can take our music anywhere, and with hundreds of songs pounding our heads daily, the brain can only take so much. Maybe it saves some to work out later.
Dr. James Kellaris of the University of Cincinnati has an even more intriguing theory: Certain properties of music may be like histamines, which cause an itch on the skin. Exposure to such music may cause a sort of “cognitive itch” in one’s mind. “The only way to scratch a cognitive itch is to repeat the offending music mentally,” according to his website. “But this only exacerbates the itch, trapping the hapless victim in an involuntary cycle of repeated itching and scratching.”
Researchers at Dartmouth University used magnetic resonance imaging to study people’s brains after listening to music and discovered that when we listen to a catchy song with parts missing, our brain will continue to work and try to fill in the missing pieces.
The ‘Phonological Loop’
They’ve also found that a short-term memory system that lives in our auditory cortex and stores a small amount of auditory information. We may store this information, such as a snippet of a song, in our long-term memory, but it stays in our auditory cortex for a longer period than we originally thought.
For some unknown reason, certain songs excite that part of the brain, forcing it to play it over and over like pressing rewind and play again. Scientists call this a “phonological loop,” and it’s sometimes impossible to break. And playing it over only makes things worse, imprinting it in our auditory cortex for longer. It’s a vicious cycle.
Which Songs are Earworms?
What particular songs induce earworms? It’s not known,, but certain songs have something that excites each individual’s auditory cortex. Some people point to “Macarena” as an earworm, but it does nothing for me. I’m sure most people would not be affected by “Wild Irish Rose.” But it’s the same concept as to why some of us are attracted to songs with a minor key, and some of us love augmented and diminished chords in songs. Our tastes are different because our brains are reacting differently to songs.
I think there’s also a heightened tendency among music lovers to have earworms. We tend to listen to more music and probably process it more than most, noting patterns, phrases and chord progressions, and it sticks with us. I think I have tunes going through my head most of the day, but most of the time they are too unobtrusive for me to even notice. If I stop and try to figure out what it is, it will go away, only to be replaced a few minutes later.
The Cure for Earworms
What helps? One respondent to Kellaris’ survey argued against trying to fight it — “It only makes it angrier!” But Kellaris found that nearly two-thirds of sufferers try to use another tune to dislodge the one that’s stuck. Others try to distract themselves, and some try to share the earworm with others in the hopes that it will pass from their head to another’s.
Somehow, though, I don’t think it’s a good idea to go up to someone and start singing “The Freaks Come Out At Night.”
