Like me, most people have faked our way through school chorus and church choir by mouthing our way all because we can’t sing very well. Aware of our poor singing, we only dare risk it in the car, with the windows rolled up, or the shower, with the water muffling our voice. If you ask, most people will tell you that they consider themselves tone deaf. A quite high percentage of people — one in seven — place themselves among the tone deaf. This site teaches you about noise induced hearing loss.
Even though tone deaf pretty much means you can’t sing well either, there are a lot of people who hear music perfectly, but sound horrible when they sing. 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. In some studies, it has been discovered that approximately only 1 out of every 20 people actually suffers from tone deafness. Folks who are actually tone deaf cannot discern disparity in pitch. They can’t hear whether a pitch is low or high. Thus, they cannot follow even an easy melody or tune no matter how hard they work.
Serious cases of tone deafness are known as amusia in research circles. Those with congenital amusia are classified as having been born with the condition. The Montreal Battery for the Evaluation of Amusia allows physicians and researchers to determine which pitches a truly tone deaf person is unable to distinguish. Permitting researchers to measure musicians’ brains against those of individuals who possess typical musical talent, new sophisticated imaging tests are available now.
Researchers are curious about the workings of a brain and it’s relation to music, which is why this research is performed. The condition of tone deafness is not something that is anticipated to be curable in the near future. Through discovering the mysteries of amusia, scientists hope that they will solve other challenges, including learning disabilities, and they believe that amusia itself could help one day with treating a number of alternative developmental disabilities.

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. The majority of humans are able to detect the differences between musical notes easily; in fact, many of us are able to recognize fractional changes between semitones. Yet individuals suffering from amusia generally require a much greater variance, before they are able to distinguish between various pitches.
They have a difficult time distinguishing pitch isolation and are unable to hear differences in pitch direction and contour. These alternating higher and lower steps in the contour of pitch are what create melody. Experiments with amusics have revealed that they can’t easily distinguish changes in pitch within a particular phrase of music.
There are those individuals suffering from amusia who struggle equally with pitch and melody as much as with rhythm. However, when playing music in monotone (devoid of melody), experiments have indicated that many amusics actually have a good grasp on recognizing rhythm. What it all comes down to, it seems, is that it is the pitch changes, even in a simple piece of music, that throw these people off, causing them to stumble on the music’s rhythm.
