The acceptable pitch range(s) for single note repetitions in music aptitude examinations

A computer-based survey was devised to find out the acceptable frequency deviation ranges for the answers given to the single note repetition questions. The range which participants deemed acceptable as successful was approximately 75 cents, distributed unevenly around the absolute correct pitch. Additionally, it was found out that besides the fundamental frequency, variables such as pitch envelope, timbre, and octave differences also affect the perceived pitch. This means that at the conservatory entrance exams, the jury members' evaluation of the prospect students might not be fair, since the effects of such variables on the evaluation processes are unknown.
