I go to the library every couple of weeks. Whenever I see a book about the brain or neurology in the new books section, I check it out.

One of them (no, I can't tell you which) said that there is no such thing as a tone deaf person. To be tone deaf, a person would be able to hear, let us say, a barking dog and cooing baby, yet not be able to tell which is which. That just doesn't make sense.

What most people mean by 'tone deaf' is a person who hears a musical tone and can't duplicate it by singing. That doesnt mean they don't hear the tune.
