Amusia is a musical disorder that appears mainly as a defect in processing pitch but it also encompasses musical memory and recognition. Two main classifications of amusia exist: acquired amusia which occurs as a result of brain damage and congenital amusia which results from a music processing anomaly at birth.Studies have shown that congenital amusia is a deficit in fine-grained pitch discrimination and that 4% of the population suffers from this disorder.
