Have you ever found yourself humming a tune long after you last heard it? This common experience, where a song seems to loop endlessly in your mind, is known as an “earworm.” But why does this happen? Let’s delve into the science behind these catchy tunes with insights from Dr. Carol Sherling, a neuroscientist at Belmont University.
Dr. Sherling specializes in behavioral neuroscience, focusing on how we perceive and process information, including music. Her research explores how music influences our emotions, memory, and mood. Music, with its ability to evoke strong emotions, serves as a fascinating subject for studying cognitive processes.
The phenomenon of songs getting stuck in our heads is clinically referred to as “involuntary musical imagery.” This occurs when we subconsciously replay a song in our minds, engaging both the lyrics and the melody. Functional MRI (fMRI) studies reveal that even when a song isn’t playing, the brain regions involved in listening to music remain active, similar to how muscles continue to work after exercise.
Mirror neurons also play a role. These neurons, which activate when we observe others performing an action, can be triggered by simply thinking about music, creating a comprehensive sensory experience.
Several musical features contribute to a song becoming an earworm. Fast tempos and catchy lyrics are significant factors. Research indicates that 74% of earworms are lyric-based, providing additional data for our brains to process.
Melodies with a rise and fall pattern, like “Twinkle, Twinkle, Little Star,” are particularly memorable. This pattern is common in nursery rhymes and famous tunes, making them more likely to stick in our minds. Repetition also plays a crucial role; familiar songs are more likely to become earworms due to memory processes like “chunking,” where repeated choruses help us remember the song.
Emotional content is another key factor. If a song resonates with your current emotional state, it is more likely to linger in your mind.
While there’s no guaranteed way to eliminate an earworm, several strategies may help. Replacing the persistent song with another tune or discussing it with someone can be effective. Interestingly, chewing gum has been shown to distract the brain, potentially reducing the earworm’s grip.
Everyone can experience earworms, but musicians are particularly prone due to their constant exposure to music. Additionally, individuals with obsessive tendencies may encounter earworms more frequently.
Understanding the science behind earworms can help us manage these persistent tunes. Music is an integral part of our lives, and by exploring its impact on our brains, we can appreciate its power even more. For more insights into the fascinating world of music and neuroscience, be sure to explore additional resources and stay curious!
Reflect on a recent earworm you experienced. Write a short essay analyzing its musical features such as tempo, melody, and lyrics. Consider why this particular song might have stuck in your head. Share your insights with classmates to compare experiences.
Work in groups to compose a short song designed to become an earworm. Focus on incorporating elements like a memorable melody, repetitive chorus, and emotional lyrics. Perform your composition for the class and discuss which features made it catchy.
Choose a popular song and play it for a group of friends. Ask them to report back after a few days on whether the song became an earworm. Analyze the results and discuss factors that might have influenced the outcome, such as familiarity or emotional connection.
Research and present a summary of an fMRI study related to music and brain activity. Focus on how these studies help us understand the persistence of earworms. Discuss the implications of these findings in a class discussion.
Participate in a class debate on whether earworms are beneficial for cognitive processes or simply an annoyance. Use evidence from the article and additional research to support your arguments. Engage with opposing views to deepen your understanding of the topic.

Hey everyone, Marty Schwartz here with Marty Music. Thanks for checking out this video! I want to talk about when you get a song stuck in your head. I’m sure you know what I’m talking about—you listen to a song a few times, and then even minutes or hours later, while you’re doing something else, that song just pops into your mind. Ever wonder why that happens?
Curiosity got the better of me, and I set out for answers. I connected with Dr. Carol Sherling, a neuroscientist from Belmont University here in Nashville, Tennessee. We sat down and discussed earworms and the neuroscience behind what happens when a catchy tune gets stuck in our heads. Carol’s deep knowledge of the brain made for a really interesting conversation. I think you’re going to enjoy it!
Let’s start the show!
Tell me a little about your background in your field.
My background is in behavioral neuroscience, particularly studying cognition—what we notice, what we don’t notice, and what makes it into our brain without us realizing it. I also study emotions, including how they affect our memory and mood, and how music plays into that. Music is a wonderful tool to incite emotion and to study differences between clinical groups and healthy groups.
In this video, we’re calling it “sticky lyrics.” The idea is about simple songs getting stuck in your head, like jingles. One of my favorite jingles is from El Pollo Loco—it’s just one note, but I can’t forget it!
So, what’s going on with sticky lyrics and music getting stuck in our heads? The clinical term we use is “involuntary musical imagery.” Essentially, you’re reciting the same song in a sub-vocal way, which applies to both lyrics and notes. Studies using fMRI scans show that when people talk about having an earworm, there’s increased blood flow to the areas of the brain used when listening to a song, even when the song isn’t playing.
It’s almost like a muscle that keeps working even after you stop. The brain continues to process this sub-vocal sound. If you’re focusing on the fact that you can hear it in your head, that area keeps activating.
There’s also something called mirror neurons. These were discovered when researchers noticed that monkeys’ neurons fired while watching others eat. The same idea applies to music—thinking about a song can activate those neurons, making it a holistic experience.
Now, let’s talk about the process that leads to songs and lyrics being stuck in your head. There are certain features of music that contribute to this. For example, fast tempo and catchy lyrics are key. Studies show that 74% of earworms are lyric-based, which provides extra data for our brains.
Songs with a rise and fall in melody, like “Twinkle, Twinkle, Little Star,” tend to stick in our heads. The most famous melodies often resemble nursery rhymes, which also have that rise and fall pattern.
Repetition is another factor. The more familiar you are with a song, the more likely it is to stick in your head. This is related to memory theories, where we learn through “chunking.” Repeating a chorus helps chunk the information, making it easier to remember.
Emotional content also plays a role. If a song aligns with your current emotional state, you’re more likely to have it stuck in your head.
So, how can you get a song out of your head? There are several strategies, but none are guaranteed. One method is to replace it with another song. Talking about it with someone can also help. Interestingly, chewing gum has been shown to distract that part of your brain, potentially helping to reduce the earworm.
Familiarity and emotional connection are key factors in how songs get stuck in our heads.
Are there certain people who are more susceptible to earworms?
Yes, everyone is susceptible, but musicians tend to be more prone to it because they are constantly exposed to music. Research also shows that people with obsessive tendencies may experience earworms more frequently.
Thank you, Carol Sherling, for this great conversation! Music is such a huge part of our lives today, and I hope this understanding helps you manage those songs that get stuck in your head.
