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. |
