I’m a musician and I have bad ears. In my ear training course in college, my teacher would play intervals on the piano. Going in a circle, he would point at the students and ask us to identify them. Some days, I got every single interval wrong. I’d confuse a minor sixth with a major sixth, or mix up fourths and fifths. Once in a while, I would panic and simply say nothing. The teacher would look at me with confusion, then sympathy, and then he would move on to one of my classmates.
