I have rebuilt my Black Forest flute clock to play and made all the
missing pipes.  It has three ranks with a total of 69 pipes.  The top
register is as short as is practical to make, the bottom rank just
fits in the cabinet.

Three octaves would mean the top register would have pipes less than
a centimeter long, or that the bottom would have pipes that fold twice.
So where do I tune the middle rank?  The flutes are in the key of G.
Help!
