No, the name has settled on A.
Correct - my bad. Middle C is listed as 261.1
Hz (but really no need to specify the UOM when it's understood from the context.)
The frequency (not pitch) has always been 440 Hz.
By pitch I mean the tone that we hear - that remains the same regardless of its name. Perhaps
pitch isn't the most correct terminology - maybe
tone would be better.
We call Bb B, and B H! Suck on that for a while
I did. It makes sense really: In such a system, from
B to
C is a whole step, just like from
A to
B.
H to C is something special - a half step that's represented by a whole letter in the spelling of the scale, but a letter that's after everything else and isn't part of the regular order of notes, which go in whole steps. I like that idea better than having a whole step between
A and
B but only half a step between
B and
C, which always strikes me as wildly inconsistent.
The problem is, what do you do with
E/F? To be consistent, In that system
Eb should be called
E, go a whole step and you get to
F. And
E we'll call
I just like
B is called
H.
And yes, I agree, a violin player would play an F sharp differently than a G flat...
As stated, I don't think that's relevant to anything - the name of the note is just a guideline in that case. Although it could be that since fretted instruments were not, AFAIK, part of the medieval orchestra, it was accepted that
F# is actually a different pitch/tone/frequency than
Gb . Although there is no formal representation of that idea in our notation, violinists, etc have that tradition and abide by it.
Which one has the preferential right of interpretation?
I think it would depend on the musical context, which would generally be reflected in the notation itself : Is it written
Gb or
F#?
