[Harp-L] head shake music theory

[rainbowjimmy@xxxxxxxxxxxxxxxx]

Yesterday I took my harp out to try and figure out how to play a harp head shake
on the piano. I'm playing the draw 5 and 6 on a D harp so that's a G note and a
B note right? Plus I alternate between straight and bent so that's Gb and Bb.
Those aren't notes I usually associate with an A blues scale yet I've used that
headshake over the A chord in 2nd position for more than 30 years.

So am I playing the right notes? Am I doing the head shake correctly? Why would
a blues musician use a Bb note in the key of A? Or a B for that matter.
