Abstract: Absolute pitch is reported to occur in 1
out of 10,000 persons, usually those trained in music
before age 6. We demonstrate that the five individuals we
tested, who have Williams syndrome, a condition caused by
a microdeletion of about 20 genes in the q11.23 region of
one of their two chromosomes number seven, possess near
ceiling levels of absolute pitch despite their limited
cognitive abilities. With these individuals, we also
describe our preliminary findings on relative pitch,
transposition, and retention. We discuss the
possibilities that (1) the incidence of absolute pitch
among individuals with Williams syndrome is higher than
that found in the general population and (2) the normal
early childhood critical period of absolute pitch
acquisition may be extended in individuals with Williams
syndrome. | |
