All you have to do is listen to Billy and his wife sing in the car and you will know that the answer is yes.

Tone deafness is the inability to recognize musical tones or reproduce them. It is also called amusia or dysmelodia. This can occur after a traumatic brain injury, but it can also be present from birth. Congenital amusia is the most common term used for tone deafness that is present from birth.

If you want to read about the first reported case of tone deafness, just go to the 1878 journal Mind and read Grant-Allen’s article “Note-Deafness.” The article describes the case of a thirty-year-old man who took music lessons as a child, but was completely unable to carry a tune or recognize familiar melodies.

Congenital amusia is similar to a learning disability. Patients do not have any brain injury, hearing loss, or other cognitive deficit.

The other end of the spectrum is perfect pitch or absolute pitch, the ability to recognize a pitch without any external reference. Perfect pitch is thought to involve both genetic and environmental factors.
