Or you simply stop listening.
As someone who has perfect pitch... Please kill me now.
Doesn't perfect pitch embrace microtonality? Curious.
Not really... I embrace the love for all of the twelve-notes being immaculately in tune, and hate it when they're not. I'm okay if the notes are in tune with each other in a twelve-note system, so if I hear a piece played by a Baroque orchestra, I can accept that it's immaculately flat, but can handle it if the people are in tune with each other. Different temperaments are a bit weird...
Actually I was born with it... no idea how you learn it.
