title: Do individuals with Williams syndrome possess absolute pitch?
abstract: Although absolute pitch (AP) is a rare skill in typical development, individuals with Williams syndrome (WS) are often referred to as possessing this musical ability. However, there is paucity of research on the topic. In this article, 2 studies were conducted to evaluate AP in WS. In Study 1, seven musically trained individuals with WS, 14 musically trained typically developing controls matched for chronological age, and 2 experienced musicians with AP completed a pitch-identification task. Although the task was a classical assessment of AP, it required participants to have musical knowledge, and the availability and accessibility of musically trained individuals with WS is very low. In Study 2, a paradigm suitable for evaluating AP in individuals without musical training was used, which made it possible to evaluate a larger group of participants with WS. A pitch memory test for isolated tones was presented to 27 individuals with WS, 54 typically developing peers matched for chronological age, and the 2 musicians with AP. Both individuals with WS and their controls obtained low results in the two studies. They showed an arbitrary pattern of response, and their performance was far from that of musicians with AP. Therefore, participants with WS did not appear to possess AP. Unlike what is usually claimed, results suggest that AP is not a remarkable ability in WS and that, as in the typically developing population, this musical ability is also rare in individuals with WS.
