Robbie,  Thanks for the info about www.navaching.com.  Just what
I needed.  I understand pipe dimensions -- what I don't know how to do
is make a "flue" like in an organ pipe.  Making a PVC pipe sound with
buzzing lips is one thing, making it sound without a human is another
thing.  How can I make a PVC pipe sound with a blower?
