With all the over-bends mentioned above, you’ll have all the notes there are over 3 octaves, but if that isn’t enough it just so happens that you also have some spare over-bent notes… Yes you can actually get an over-bend on each hole and you’ll notice that I’ve missed out holes 2, 3 and 8, that’s because the over-bent notes on those holes are repeated notes that you can get from normal playing:
2 overblow = 3 full draw bend
3 overblow = 4 blow
8 overdraw = 9 draw
Why not try them out, maybe they’ll fit in with that lick you’re working on better than the ‘normal’ way.
