answer:It’s hard to say what is cultural or learned, and what is innate hearing difference. I worked with a man who was born in China, and is a Chinese musician; much of what he plays and listens to is so discordant to me. Some people love symphonies, others like rap; neither is my preference. But there are differences in the way we are wired, too. My children hear harmonies that are nothing to me, I can’t hear them at all. My parents used to say I have the voice of an angel, a friend relieved them of that error by saying “yes, a Hell’s Angel.”
