Thanks Doug, I did misread the quote - and thanks for clearing it up for
me.

One more point to jump on, and then I'll leave it alone:

The end of Bill's quote mentions the tip of the reed now returning to the
mouthpiece.....while I would agree there is some kind of movement of the
reed that touches the rails of the mouthpiece in some way, I do not
believe it ever touches the tip of the mouthpiece while vibrating. The
curve is simply too much to allow for it to. I also think the sound would
close off......so, I am not sure if the quote is accurately presented, or
if it simply is false information. Either way, it looks suspect to me.

Thanks again for the clarification - it helped me better understand the
intial quote!
