[Harp-L] Inverted notes on major scale at hole 7

["Rodrigo G. Reis" <rodrigogreis@xxxxxxxxx>]

Hey guys,

Just another day, a guitarrist friend of mine who just got him self a
harmonica, asked me why on the major scale the sequence of blow-draw is
inverted to draw-blow at hole 7 and it goes inverted until the end (hole
10). I didn't have any musical based answer to it.

Do you guys have something on it?

Thanks in advance,

Rodrigo G. Reis
