Hi Dan.

Can you calculate the width of the piano it would take to play Bb 57 octaves
below middle C or the length of the string to resonate at that frequency?
Of course you'd have to add  53 octaves on treble side to keep middle C in
the middle.

Wish my math skills were as good as yours.

you would have to divide 256 by 2 successively 57 times.  My calculations
(which admittedly could be wrong) show that this would be a 'frequency' of
0.00000000000000710542735760, or one 'sound' impulse every 140737488355328
seconds, which works out to be a vibration-beat every 8,925,512.96 years.
