Hi, I’ve played guitar for over 30 years. Love the blues. I’d like to try some harmonica. So I got a key of A to play some E blues music in cross harp. It just didn’t sound right… So I looked at the notes and see I’m playing a mixolydian scale. No b3rd note. Most all the blues I play is using a b3. In fact the “blues scale” is your b3rd.
So my question: Wouldn’t a natural minor key be the best for me to play blues? E natural minor for a E key - basically a dorian mode. I’d rather not have the 2nd and 6th and I’d rather have the #4 added though.
From what I understand I can play a Bb harmonica in 3rd position slant harmonica for a key of C for the dorian mode also. But It would sure be nice to have the root of the key on draw 1 etc. To me it just seems like it’d mare more sense.
Why is there none in the “blues key” though? 1 b3 4, #4, 5, b7?
