Amusia
Amusia is also known as tone deafness. Amusics primarily have deficits in processing pitch. They also have problems with musical memory, singing and timing. Amusics also cannot tell melodies apart from their rhythm or beat. However, amusics can recognize other sounds at a normal level (i.e. lyrics, voices, and sounds from the environment), therefore demonstrating that amusia is not due to deficits in exposure, hearing or cognition.
