I was told early on I have perfect pitch by several different music educators. They tested me when I was young. I didn't know it was a "thing" to have, I just have it. I do have a sense of humor, so I can play in any setting. It can be very "painful/distressing" if I let it, especially in a church setting (OH MY GOD!!!). I would hum the chord in my high school choir so we all started out in tune. I wish more singers just had relative pitch!
