Vocal pitch shift in congenital amusia (pitch deafness)

► We pitch shifted vocalizations of congenital amusics and controls in real time. ► Half of amusics showed a normal pitch shift response, half showed none. ► Pitch shift response occurred to small and large shifts. ► Vocal pitch matching accuracy predicted size and presence of pitch shift response. ► Results suggest a dissociation between pitch perception and production abilities.
