>A candidate needs perfect pitch. Why? Traditionally, organs are tuned by listening to the beats[0] between pairs of notes. If you want to tune to specific frequency (such as the modern A=440Hz standard) you only need a single frequency reference, such as a tuning fork. But historically there have been an enormous variety of tunings used in pipe organs, many of which were built before A=440Hz became standard, and in any case, the tuning is affected by temperature, so it will drift as the seasons change. I think that company is needlessly limiting their options by requiring perfect pitch. Good relative pitch perception is sufficient.
