Cb major - life is full of complications,
commitments and organisation. You love to make
sure everything is just perfect, but sometimes
this can cause you to fall over your own feet.
A slightly unsociable key: why Cb major when
you could be the identical Bmajor? It has less
accidentals.

what key signature are you?

OK, mister smartypants, how are they not identical?

Is fB his own musical key, i wonder...

The following is a I-IV-V progression: Gb Cb Db

The following is not: Gb B Db (though F# B C# is)

Right, it's just music nerdery. The notes are the same unless you're using a different scale.

Actually, I think the notes might have slightly different frequencies, depending on what sort of temperment you're using.

Assuming C4 = 261.63Hz and Just temperament:
15/8 = ratio of major 7th to fundamental
4/3 = ratio of perfect 4th to fundamental
2/1 = ratio of ocatave to fundamental

B3 = (261.63 x 15/8 / 2) = 245.28

To get to Cb, we need to traverse the circle of fourths:
C -> F -> Bb -> Eb -> Ab -> Db -> Gb -> Cb

F4 = (261.63 x 4/3) = 348.84
Bb3 = (348.84 x 4/3 / 2) = 232.56
Eb4 = (232.56 x 4/3) = 310.08
Ab3 = (310.08 x 4/3 / 2) = 206.72
Db4 = (206.72 x 4/3) = 275.63
Gb3 = (275.63 x 4/3 / 2) = 183.75
Cb4 = (183.75 x 4/3) = 245.00
