Tone Deaf

Image result for tone deaf

Many people claim to be
tone-deaf (technically called amusia) although it has been estimated that only
about 4% of the population actually have the condition. This disparity between
actual and claimed amusia is probably because it’s an excellent way of avoiding
singing in public – I’ve used it on many occasions. However, researchers have
found the condition to be incredibly specific.
It seems that ‘congenital
amusics’ have no problems in hearing music or other environmental sounds. They
generally have no perceptual problems and can, paradoxically, detect pitch
changes in speech that they cannot detect in music. Music seems to require a
much more fine-grained differentiation of tones than any other form of auditory
perception.
Amusia may be similar
developmentally to dyslexia. In populations that speak tonal languages like
Vietnamese and Cantonese, amusia is almost unknown – perhaps practice at a
young age makes perfect. Recent research suggests that children can be trained
to discriminate tones but adults are normally stuck with their disability.
However much practice you get
at a young age, the skill can be affected by brain damage. Neurologists at the
University of Tokyo report the case of a 62 year old professional tango singer
who lost her singing ability after a stroke that affected a tiny part of her
brain. After a period of recuperation from the stroke she experienced no other
deficits in cognitive functions, other than amusia – a cruel fate for a professional
singer.
