Re: Absolute pitch discussion
The PNAS paper suggests a genetic basis for AP, but actually does not
present any evidence for this. Awaiting this evidence, others —not
cited in this paper— have argued and shown that it is more likely 1)
a result of training (e.g., Vitouch, 2003), or 2) simply a result of
biases due to the task and stimuli used. For example, Schellenberg
and Trehub (2003) find support for a normal, not bimodal,
distribution once pitch-naming or reproduction requirements are
eliminated and familiar materials (such as soundtracks of tv
programs) are used.
