[Harp-L] Correctly Naming a More Ordinary Blowing Technique

[Bradford Trainham <btrainham@xxxxxxxxxxxxx>]

So...  If over-blowing raises the pitch... what is the name of the
ordinary technique, available to us on even the most tetanus-infested
shoddily-produced diatonic that will lower say the 5 hole anywhere
from a half to a whole step downward. 
I discovered that one a long time ago by accident, got better at it
once I realized Jimmy Reed was using it... not by accident, but I've
never known what that occultism-of-harp is called.
