Research on Perfect Pitch
Perfect pitch reconsidered
This review suggests that perfect pitch (AP) likely has a genetic
predisposition, requires early musical training, and may interfere
with relative pitch perception. It also questions the overall value
of AP for musicians.

Absolute pitch and planum temporale
This study explores the neural basis of absolute pitch (AP) and
relative pitch (RP) processing. It suggests that AP might be a
deviation from the typical development of RP ability.

Critical periods for absolute pitch acquisition: A
twin-study
This study challenges the critical period theory of AP acquisition
by demonstrating that some adults with high auditory working memory
can learn AP through intensive training.

Neural representations of pitch in absolute and relative pitch
possessors
This study uses EEG to investigate the neural representations of AP
and RP in musicians. It finds that AP musicians have a higher
representational similarity between listening and labeling pitches
compared to RP musicians.
