I think it's completely ridiculous whether or not you have the ability to identify what a certain note is. As a matter of fact, I do have perfect pitch. However, what I learned as a child was the pitch of the piano at that time, or around 438Hz, not 440Hz. Now, however, they use a higher pitch of 442Hz or 445Hz, so when I think of "fa," it's really a little bit low. But that doesn't mean that I'm no good. There's something called relative pitch, and all musicians have the ability to sense that everything is too high or too low, for example, and rectify it. Also, having a sense of the sound is unrelated to having perfect pitch, and most people are not born with it, but acquire it as they go on playing music. But that, too, is something that nonprofessionals will not understand -- instead, only those who are actually in the field of music will know about it. And when people who don't understand something talk about what they don't know, they end up sounding even more clueless.
