The genetics of congenital amusia (tone deafness): a family-aggregation study.
Congenital amusia (commonly known as "tone deafness") is a lifelong impairment of music perception that affects 4% of the population. To estimate whether congenital amusia can be genetically transmitted, its prevalence was quantified by direct auditory testing of 71 members of 9 large families of amusic probands, as well as of 75 members of 10 control families. The results confirm that congenit...
متن کاملCongenital amusia: a group study of adults afflicted with a music-specific disorder.
The condition of congenital amusia, commonly known as tone-deafness, has been described for more than a century, but has received little empirical attention. In the present study, a research effort has been made to document in detail the behavioural manifestations of congenital amusia. A group of 11 adults, fitting stringent criteria of musical disabilities, were examined in a series of tests o...
متن کاملMusical Disorders: From Behavior to Genes
Research over the last decade has provided compelling evidence that the ability to engage with music is a fundamental human trait, yet the biological basis of music remains largely unknown. Recent findings indicate that a small number of individuals have severe musical problems that have neurogenetic underpinnings. Such deficiencies are termed congenital amusia, an umbrella term for lifelong mu...
متن کاملCongenital Amusia (or Tone-Deafness) Interferes with Pitch Processing in Tone Languages
Congenital amusia is a neurogenetic disorder that affects music processing and that is ascribed to a deficit in pitch processing. We investigated whether this deficit extended to pitch processing in speech, notably the pitch changes used to contrast lexical tones in tonal languages. Congenital amusics and matched controls, all non-tonal language speakers, were tested for lexical tone discrimina...
