Tone Deafness: What Causes It And Is There A Cure?

You're not alone if you think you can't sing; if you watch closely, you'll find you're not the only one simply mouthing along with the school chorus or the church service. Chances are the only time the average person feels comfortable singing is in the shower or alone in the car - of course, with the windows closed. If you feel you may be tone deaf, you are by no means alone. Approximately one out of every seven people believes he/she is tone deaf.

A lot of people think the term tone deafness refers to be not being able to hold a note. However, tons of folks cannot themselves sing, but they can listen to music and actually find music very enjoyable. A much smaller amount of people would be considered tone deaf if the term was used in it's truest sense by describing someone's difficulty perceiving music. Researchers employing music listening studies have determined that really only five percent of the population is actually tone deaf. People who have this sort of deficit are unable to distinguish between high and low musical notes, which makes it difficult if not impossible for them to follow along with a simple tune.

The true clinical term for being tone deaf is called amusia. When an individual has been tone deaf from birth, we refer to that condition as congenital amusia. There are various tests that have been developed such as the Montreal Battery for the Evaluation of Amusia, that allow researchers to better define varying degrees of musical deficiencies. Permitting researchers to measure musicians' brains against those of individuals who possess typical musical talent, new sophisticated imaging tests are available now.

Our fascination with music and how it's perceived and interpreted by different people has spurred on this form of research. At the present time, a tone deafness treatment is not being pursued. However, the investigation of amusia does help us understand other disabilities that are caused by developmental issues, such as certain learning disabilities, and by understanding amusia, we may be able to solve these other more serious problems.

Western music happens to be made up of semitones, or half steps, for instance the difference between a F and F-sharp, or a B and B-flat. Typically, even musically untalented folks can still discern the difference between half steps. The bulk of us can tell the difference between notes that only a fraction of semitones apart. People with amusia can't recognize differences in musical pitches unless they're given a wide range of sounds to listen to.

The contour and direction of pitches (also known as pitch isolation) is another difficulty shared by those who are tone deaf. It is the variations in pitch contour which creates the melody of all types of songs. Research has demonstrated that people with amusia truly cannot pick out a shift in the pitch of note within a musical phrase.

With very pronounced amusia, people cannot pick out rhythm or melody, as well as pitch. When in fact, plenty or tests prove that when music is played monotone, amusics possess fairly good rhythm. What this shows is that when a person with amusia listens to music, it is actually the variations in pitch that confuse their ability to get the rhythm of the song as well.
