[Harp-L] the flat third

["hazcon" <hazcon@xxxxxxxxxx>]

Just wondering here; why wouldn't you ,if you were setting up a Harp to play 
straight Blues only,  retune the 8 blow a 1/2 step down to give a permanent 
flat note.
        (I know that you wouldn't really tune it a whole 1/2 step to get 
the correct blue note)
I can't see any real disadvantages and a few advantages.
Its not a note that is crucial on any of the chords in the 1 1V V ie it is 
the 6th on the 1, the 3rd on the 1V and the 2nd on the V.So it is actually a 
note to 'avoid' on the 1 and V during a blues as such.(pentatonic scale)
         And on the 1V it sounds better slightly flat.
I don't want to put words into his mouth but I'm pretty sure that Brendan 
Power  used to do this to his harps .
          Any thoughts?
