Oh yeah...I think this is closer to where Nick is coming from in terms of tutelage...but as far as referring to any given note is concerned, I'm with DTB on this, i.e always refer to the key sig..no such thing as a # in a b sig.

I still haven't mastered the art of inserting a youtube link and getting a graphic......pah!
I think my stage piano has the ability to re tune but I don't know whether it allows individual notes to retune or just the whole instrument....I will consult the manual if I can find it and report back....don't hold your breath though cos I haven't touched it(the piano) in over ten years....
interesting video. But no, I agree entirely that there is no such thing as a # in a b sig, I was just trying to allow Chris to have more than 11 notes in the drummer playing guitar clip. And just trying to out pedant Dave that in a non equally tempered world then the notes actually vary in frequency depending on the key the instrument is tuned to. And if they are in a different key then what was a b may become a #, and because of the non equal tempered problem may actually be a different frequency.
The 3:2 ratio for a perfect fifth thing is the simplest way I know of pointing out why a equally tempered system is in one sense out of tune by more or less amounts. The 3:2 ratio is what you would get if you were trying to find a 5th interval out of a string by looking for harmonics. But if you use that interval to generate your octave you end up with a inconsistent set of intervals where a cycle of those intervals don;t take you back to where you started.
And before you say that its just a made up thing based on numbers, so is the twelfth root of two ratios that the equal temper system is.
Takes me back to realising why analogue synths uses a log converter for frequency so it was 1v per octave, not 1v per 1000Hz or whatever.
Whenever an honest man discovers that he's mistaken, he will either cease to be mistaken or he will cease to be honest.
