This is related to a previous question (which has some useful answers):
I understand what the blues scale is, and that it involves using 2nd position. To set the scene, supposing the band is playing in G, so I must use a C harmonica if I am playing in 2nd position, ie using (-2(G) -3’ 4 -4 -4’ -5 6).
It looks as if I would have to restrict myself to playing only notes from the blues scale (-2 -3’ 4 -4 -4’ -5 6). Here is my question: How am I supposed to NOT play any other notes by accident? Or is this just a question of brute force memorisation, so I always know when I am playing notes from the blues scale?
BTW I realise that playing notes not the blues scale is allowed occasionally.
with thanks,
Jim
