“…Although it seems likely that early and intensive musical training is necessary to develop absolute pitch (AP), these do not seem to be sufficient conditions, and the factors, genetic or otherwise, that interact with this training to dispose the individual to the acquisition of AP are still very much in question (Takeuchi and Hulse, 1993;Baharloo et al, 1998;Zatorre, 2003). A considerable amount of research has delved into various behavioral aspects of AP (Takeuchi and Hulse, 1993;Ward, 1999), but relatively few studies have investigated its neural correlates (Klein et al, 1984;Hantz et al, 1992;Wayman et al, 1992;Zatorre et al, 1998;Keenan et al, 2001). Electrophysiological studies using eventrelated potential techniques Wayman et al, 1992), for instance, have mainly shown a reduced P300 component among AP musicians in auditory oddball paradigms.…”
