Hello John Kleinbauer,  thanks for your article about the little
organ pipe.  It reminds me of my childhood.

When I was a boy we used to make flutes from willow twigs.  With our
pocket knives we carved the holes and, after knocking the bark for a
while, we could separate it from the core.  The mouth piece was made
as you described.  It is pleasant memory.  (See also Salizional.)

Best regards,

Horst Mohr
