Tuning article, Echo comb

[Eppingr8@xxxxxxx]

Didn't mean to send the tuning article anonymously- sorry.

There was also a question about the little holes in the comb of tremolo
models.
The reason they are there is to allow for even distribution of air to both
the upper 
and lower reed, assuring an even tremolo sound even if the harmonica is not 
perfectly aligned to the mouth.  I'm not sure why it is that the lowest and
highest 
reeds do better without these vent holes; many designs were arrived at exper-
imentally, without fully understanding the principles involved.
