After having glanced at Jeremy's recent communication, here is another
variable to throw into the PVC flute works. If you've been working with
this pipe, try bending the bottom end sort of like a bamboo shakuhachi.
What happens to the tone and responsiveness? Point is that makers of bamboo
shakuhachi have known for a long time that altering the bore on the inside
radius of the curve is not the same as altering the bore by the same amount
at the same place on the outside radius of the curve. Something about the
velocity of sound not being the same for both radii as it goes around a
curve. Something going on here that can make a lot of difference in tone
and responsiveness.
