josepp says: Now, that was stupid, wasn't it? You know you're going to get proven wrong. I'm looking at sheet music for a song called "You Don't Know My Mind" and in the 4th measure--lo and behold!--a B-sharp.

Since you clearly didn't understand a thing of what I was talking about, it's hard for me to feel proved wrong. I'd normally enjoy making myself more clear to you, but you'd have to be a lot less of a jerk to make me want to.

I'll refresh it for you: It's about the fact that B-sharp exists not whether you've ever ecncountered in your music. Are we stright now?

No, it's about whether or not a teacher was a fraud and a danger to our culture because you heard second hand that he said that B# and C are the same note or something. And it has become about whether or not someone can be a good musician if they don't ever consider the concept of a B#.

Of course everyone here knows that B# exists, if you happen to be reading music in C#. Everyone also knows that, in equal temperment for most instruments, B# and C are the same note, the only difference being that it is more convenient to write one or the other depending on what key you're in.
