Okay, so you can make a sound-alike copy of an existing flute. What I
want to know is, can you make an arbitrary flute according to a
numerical specification? Something like a computer controlled lathe
perhaps?

The reason I ask is, if someone comes up with a mathematical model
for a shakuhachi, the way to test it is to design and build "extreme"
flutes. You could make two flutes, one with a strong Ri, and one with
a weak Ri but otherwise identical, for example. You'd want to make
dozens of unusual (unplayable?) flutes, pushing the various
parameters to their limits, so the process shouldn't be too expensive.

Nelson has been doing something similar with simple PVC pipe
experiments. Someday, someone will want complete control of the
entire shape. How would they go about it?
