Description : Tune deafness, or congenital amusia, is a lifelong deficient in music perception that
cannot be explained by hearing loss, brain damage, intellectual deficiencies, or lack
of exposure. The disorder affects predominantly the melodic pitch dimension (summary
by Peretz et al., 2009). See 159300 for an opposite situation, that of musical perfect
pitch.;
