Welcome aboard, Richard. You’re going to learn a lot from JP and his lessons. He has a lesson on deep relaxed mouth position that will help you with your determining if you are doing it right or not.
I’m currently almost halfway through. I struggle with the single notes though I AM slowly getting them. But I REALLY love the Harmonica Boot Camps - anyone who skips those because they already know how to do it are missing a TON of fun.
Even if you don’t need the practice or you already know all about what he’s doing (mostly holes 1-2 draw/blow with one of the Boot Camps having you jump up higher and back down to 1-2 then up again however you feel like doing it which was GREAT fun and another where you’re working with your hand positioning while drawing/blowing on 1-2 holes and using whatever hand position you want however you want whenever you want. That was great fun too.)
I highly suggest when you get to the Boot Camp videos, if you’re doing his Happy Harpin’ videos which I also highly recommend (no I am not a paid actor or endorser, I simply love the laid back style and step by step that JP does that makes it FUN to learn even when getting frustrated like I do.) that you work through them even if you don’t “need” to simply because they are great fun!
Hope you find lots to learn here and again, welcome aboard (by the way, I tend to talk too much if you haven’t noticed ;D )
