Excepting where he specifically tells us [WTC], we simply do not know why Bach
chose the keys he chose. No better than we know why he composed his op.1 in B
[= Bb] and gave the 1st movement ||:21:||: 38:|| measures. The choice of key
may have had a similar symbolic value to that which my interpretation gives to
the above measure numbers. I think the chance is very small that the choice of
key was related solely to sound.

Is it really true that the P&Fs w/ many ## move toward keys w/ fewer ## [rather
than the other direction] before returning to the tonic? That would give them
a Very Different Harmonic Balance from what we observe in other works. And if
this is really true, then we should also expect the P&Fs in many flats to move
much more emphatically, or much further, in the # direction; this would also
make the normal subdominant confirmation of the authentic cadence problematic -
tho perhaps not to JSB. Somebody has probably tabulated all those chords &
internal cadences: does anybody here know a reference?
