About 1 in 10, people in the United States have perfect pitch, while the majority of us have relative pitch , or the ability to determine the pitch of a note relative to another note that is played before it or after it.
So, what's the reason for the wounded warbles that are emitted from a tone-deaf singer's mouth? Why can't they distinguish pitch? The brain is still quite mysterious to us, but we know it has a very adaptable nature.
People seem to have a range of ability within a given skill set, and their ability can float within that range depending on frequency of exposure or practice.
A person with poor pitch perception may be able to improve his or her ability to differentiate pitches or mimic them, but a person who is truly tone deaf may not have the capacity to improve whatsoever no matter how much he or she practices.
The level of exposure to music as a child may play a part, in that the brain may have reduced capacity for pitch mimicry. But this -- nor any other environmental factor -- doesn't account for tone deafness.
Tone deafness seems to be entirely hereditary, and identical twins score similarly when taking pitch tests [source: Barrie ]. As we mentioned earlier, it's not the reception of the tone that is compromised, but the brain's processing of it. And though there is still a great deal to learn about the brain, advancing technologies are providing us better glimpses of how communication occurs between regions of the brain.
Researchers have used MRI -like scanning techniques to examine a portion of the brain -- the arcuate fasciculus -- that is a bundle of nerves that delivers information from one part of the brain to another. While there may be other functions occurring, one of the known roles of the arcuate fasciculus is to relay signals concerning the perception of sound to parts of the brain related to reproducing that sound. In tone-deaf people, however, these nerve fibers were much smaller than normal [source: Society for Neuroscience ].
One particular branch of the arcuate fasciculus couldn't be found at all in the tone-deaf subjects. This band of nerves also seems related to the ability to repeat verbatim a sentence that has been spoken by another person. This condition, conduction aphasia , is entirely separate from tone deafness, but seems to be caused by a similar disruption or diminishment of the arcuate fasciculus [source: Bernal ].
So if you tell a tone-deaf person "nice singing" after they've left the karaoke stage, don't do it too snarkily: Tone-deaf people can detect sarcasm and other tonal variations in the human voice.

But at the end of the month, not only did they fail to improve on the tests, how poorly they scored correlated with how much music they reported listening to. A new study published in the journal Brain takes it back a step by trying to figure out exactly where the brains of people with amusia go wrong. While subjecting participants to a basic melody-recognition test, researchers in Lyon, France studied their brain activity using magnetoencephalography MEG scanners.
They found that amusic people's difficulties on the test stemmed from delayed or otherwise impaired functioning of two areas of the brain, the frontal and auditory cortexes, during the early encoding of melodic information. What's more, the researchers detected physical abnormalities in those brain areas.
For example, they had more grey matter and less white matter than is usual in the frontal cortex. This "convergence of functional and structural brain differences" appears to explain people with congential amusia's inability to both process pitch and retain short-term memory of melodies.
But a next step could be to explore training programs that might improve people's pitch perception and memory -- those two basic skills essential to the ability to recognize music. They would probably have to be more focused than just making patients listen to more music. And while, sure, there are more life-and-death things we could be focusing on curing, understanding the neurological basis of amusia could help researchers understand other learning disorders, including the flip side of the coin: language impairments.
Even as the picture of what's going on in the brain becomes more clear, it's hard to really understand what it must be like to be completely tone deaf, just as, for people with amusia, it's probably hard to understand what the big deal is.
A lot of people with amusia don't seem very distressed by their condition, but that could just be because they don't know what they're missing. The original participants in Peretz's study only identified themselves as unable to sing in tune because they had been informed of this inability by others.
Still, the majority claimed not to appreciate music, with two going so far as to report finding music unpleasant and going out of their way to avoid it. Your singing skills will improve and a talented vocal teacher can select pieces that help to develop your singing and your voice. By taking singing lessons, instrumentalists learn techniques that help them to learn songs more quickly. Singing also teaches them important skills about recognizing the music on the page and understanding what should be coming out of their instrument.
With improved sight singing skills, instrumentalists can better understand the music and can quickly identify places where they may be hitting a wrong note or playing a rhythm incorrectly.
Taking music lessons is the best way to learn to match pitch. Using a digital tuner and singing scales with a tuner can help you to gain better control over your vocal pitch. However, people with amusia can identify the emotional intensity contained in music. All of our music teachers are professionals trained to help you learn and meet your goals.
