Body Temperature change may influence on the performance of absolute pitch (AP) possessor because the auditory organ has a mechanical structure. An AP possessor was asked to measure body temperature and tune a sound generator to A4 (440Hz). The body temperatures and corresponding frequencies were recorded. Although correlation coefficients between body temperature and determined frequency was insignificant, there was some limited period where R^2>0.7 with temperature coefficient about -3Hz/K. It was shown that cochlear temperature must be regulated to within 0.1K to achieve 0.1% of frequency discrimination.
