When I am playing an Am blues with a i-iv-V progression, at the time of the Dm7 chord, which note/scale should I use?
On the Dm7 chord, can I change from the Am blues scale to a Dm scale? Or can I stay on an Am blues scale? I ask because the Dm7 chord contains an F note which is not in the Am blues scale.
On the Em7 chord, can I stay on the Am blues scale and play the C note? Or maybe on the Em7 chord I should bend the C note to a D note to match the notes in the Em7 chord? If I do either of these, would it be wrong?
When playing over a i-vi-ii-V progression, the ii is a Bm7 chord, but a B is not in the Am blues scale, so how can I use that note? And if I use a B note, will it be wrong since it's outside of the Am blues scale? Similarly, on the ii chord, how can I use an F# note which is out of the scale even on Am pentatonic or Am blues scale?
