Perfect pitch is overrated. In college as a music student with excellent relative pitch, I routinely outscored peer students with perfect pitch when taking classical ear training courses. Perfect pitch is more of a parlor trick. It's occasionally useful when trying to tune a stringed instrument by yourself, and distracting if your ensemble starts to drift off key while remaining in tune with each other. Also, trained…

First, someone with "untrained" AP (I assume you mean no musical training) wouldn't be in a position where they'd be needing to transcribe a Bach chorale, would they? Any AP possessor with musical training--I am one--finds transcription trivially easy since there's only rhythm to figure out. While it can be momentarily…

I mean, even tone-deaf people don't experience the kind of difficulties that people with colorblindness experience. You could just say that I could never entirely understand the benefits of having perfect pitch since I don't have it, and maybe that would be true, but I have literally never experienced a professional musical situation where I felt or thought, "Oh man, if only I had perfect pitch - I would have succeeded where I just failed." And this includes directing gigs, accompanying gigs, performance gigs, etc.
I'm occasionally wistful I don't have synesthesia just because that sounds actually expansive, but I don't pine for perfect pitch at all.
