Well, yes, turning faster would of course increase the tempo... but I was
thinking it would also increase the pitch and wondering whether that would
discombobulate folks with a good sense of (if not perfect) pitch. I think
pitch is what you mean when you say the key goes up a full musical step,
but speeding up from 45 to 48 rpm probably wouldn't up it that far,
pitch-wise the music would be in no-man's land.

Digressing somewhat, actually C-sharp and D-flat are not supposed to be the
same pitch although since the advent of the modern piano everybody except
strings treats them the same.  I believe in the age of harpsichords the
instrument would be tuned for the key of the work that was to be played so
as to generate the true pitches.
