Meet Mrs. L, a vibrant sixty-seven-year-old woman with a unique perspective on music. Despite her intelligence, Mrs. L couldn’t grasp the concept of “singing.” To her, music sounded like a chaotic clatter of pots and pans in the kitchen. When she attended an opera, it was nothing more than a cacophony of screams. This unusual perception is not exclusive to Mrs. L; approximately 4% of the population experiences a condition known as “amusia.”
Amusia is a neurological condition that affects the brain’s ability to process music. Often referred to as tone deafness, it impairs an individual’s capacity to distinguish between different pitches or musical notes. In some cases, amusia manifests as beat deafness, where individuals struggle to move in sync with a musical rhythm. In its most severe form, people with amusia may not recognize musical information at all.
Recent research has delved into why individuals with beat deafness find it challenging to keep a beat or tap along with music. The study involved two participants with beat deafness and a control group. Initially, participants tapped at their own pace to establish their internal rhythm. They then listened to a consistent auditory beat and tapped along with a metronome. Finally, they tapped to a disrupted auditory beat that included unexpected changes.
The findings revealed that while beat deaf participants tapped at their natural rates similarly to the control group, they struggled significantly with the auditory and perturbed beats. This suggests an impairment in their auditory cortex’s ability to perceive the musical beat and translate it into movement.
Although the precise mechanisms in the brains of those with amusia remain unclear, several brain regions are involved in music processing. Interestingly, the ability to move to a beat is not unique to humans. Other species with vocal learning abilities, such as dolphins, seals, parrots, and even cockatoos, can also keep a beat.
One fascinating example is Snowball, a cockatoo who gained fame for his dance moves. Researchers played The Backstreet Boys’ song “Everybody” at various tempos, and Snowball showcased an impressive ability to keep a beat at higher tempos, though he didn’t respond to slower beats. His movements didn’t mimic any natural behaviors typical of his species, indicating that he was genuinely dancing to the beat.
If cockatoos can follow a beat, it raises the intriguing possibility that a small percentage of birds might also experience amusia, similar to humans. There have even been reports of tone-deaf birds failing to recognize mating calls, which can disrupt their social structures. Like Mrs. L, these birds may struggle to perceive pitch and musical notes effectively.

Here’s a sanitized version of the transcript:
Mrs. L was a young-looking sixty-seven-year-old woman. She was intelligent, but she didn’t understand what “singing” meant. Her perception of music was quite different from most people’s. In Oliver Sacks’ book *Musicophilia*, Mrs. L described music as sounding like pots and pans being thrown around in the kitchen. She mentioned that when she attended an opera, it all sounded like screaming. This condition isn’t unique to Mrs. L; about 4% of the population is born with a condition known as “amusia.”
Amusia is a deficit in the brain’s ability to process music. Sometimes referred to as tone deafness, it affects individuals’ ability to differentiate between pitches or distinguish musical notes. In some cases, amusia can manifest as beat deafness, which is the inability to move in time to a musical rhythm. In the most severe cases, individuals may not recognize musical information at all.
A recent study examined why individuals with beat deafness struggle to keep a beat or tap along with music. Participants included two individuals with beat deafness and a control group. They were asked to tap at their own rate to gauge their internal pulse. Next, they listened to a regular auditory beat and tapped along with a metronome. Finally, they tapped to a perturbed auditory beat, which included unexpected changes.
Researchers found that the beat deaf participants did not vary significantly from the control group when tapping at their natural rates. However, they performed significantly worse with the auditory beat and the perturbed beat. This suggests that the process of perceiving the musical beat in their auditory cortex and translating it into motion was impaired.
While the exact mechanisms in the brains of those with amusia are not fully understood, several regions are involved in music processing. Interestingly, the ability to move to a beat is not exclusive to humans. Other species with vocal learning abilities, such as dolphins, seals, parrots, and even cockatoos, can also keep a beat.
One notable example is Snowball, a cockatoo who became famous for dancing to music. Researchers played him The Backstreet Boys’ song “Everybody” at different tempos, and he demonstrated impressive ability to keep a beat at higher tempos, while he did not respond to slower beats. His movements did not mimic any natural behaviors typical of his species, indicating that he was genuinely dancing to the beat.
If cockatoos can follow a beat, it raises the possibility that a small percentage of birds may also experience amusia, similar to humans. There have even been instances where tone-deaf birds fail to recognize mating calls, disrupting their social structures. Like Mrs. L, these birds may not perceive pitch and musical notes effectively.

Music – The art or science of combining vocal or instrumental sounds to produce beauty of form, harmony, and expression of emotion. – In the psychology of music, researchers study how music can influence mood and cognitive processes.
Psychology – The scientific study of the human mind and its functions, especially those affecting behavior in a given context. – Music psychology explores how different genres of music can affect emotional and mental states.
Amusia – A musical disorder that appears mainly as a defect in processing pitch but also encompasses musical memory and recognition. – Individuals with amusia may struggle to recognize familiar tunes or differentiate between musical notes.
Beat – The basic unit of time in music, a regular pulse that underlies the rhythm. – In music therapy, the steady beat of a drum can help synchronize brain activity and improve focus.
Rhythm – A strong, regular, repeated pattern of movement or sound. – The rhythm of a song can significantly impact a listener’s heart rate and emotional response.
Auditory – Relating to the sense of hearing. – Auditory perception is crucial in music therapy, as it involves how we interpret and respond to musical sounds.
Perception – The process of organizing, identifying, and interpreting sensory information to represent and understand the environment. – Musical perception involves how the brain processes different elements of music, such as melody and harmony.
Cortex – The outer layer of the cerebrum, involved in complex brain functions such as thought and action. – The auditory cortex plays a vital role in processing musical elements and is a focus in studies of music cognition.
Participants – Individuals who take part in a study or experiment. – In a study on music and emotion, participants were asked to listen to various genres and report their feelings.
Tones – Sounds with a specific pitch and quality, often used in music to create melodies and harmonies. – The ability to distinguish between different tones is essential for musicians and is often tested in psychological studies of music perception.
