A little theory help

I’m a bass player learning harp and i created this chart as a memory aid for 2nd position on a diatonic. Can anyone with theory knowledge check it for me? It should work in every key.

Could you explain it for me? I’m one of those idiots that can’t figure out the simple stuff, so I need help! Then I could try to check it for you. lol


It’s based on a major scale. A I-IV-V progression is the usual blues chord progression. The other numbers under and over the holes are the other notes of the major scale. The b’s are the in-between notes. This should hold true on all diatonic harps, but I want someone with a little more knowledge to confirm. The chart will just help with my understand of the construction of riffs and transitions.
